What are the treatments for Respiratory Distress Syndrome ?
Treatment for respiratory distress syndrome (RDS) usually begins as soon as an infant is born, sometimes in the delivery room. Most infants who show signs of RDS are quickly moved to a neonatal intensive care unit (NICU). There they receive around-the-clock treatment from health care professionals who specialize in treating premature infants. The most important treatments for RDS are: Surfactant replacement therapy. Breathing support from a ventilator or nasal continuous positive airway pressure (NCPAP) machine. These machines help premature infants breathe better. Oxygen therapy. Surfactant Replacement Therapy Surfactant is a liquid that coats the inside of the lungs. It helps keep them open so that an infant can breathe in air once he or she is born. Babies who have RDS are given surfactant until their lungs are able to start making the substance on their own. Surfactant usually is given through a breathing tube. The tube allows the surfactant to go directly into the baby's lungs. Once the surfactant is given, the breathing tube is connected to a ventilator, or the baby may get breathing support from NCPAP. Surfactant often is given right after birth in the delivery room to try to prevent or treat RDS. It also may be given several times in the days that follow, until the baby is able to breathe better. Some women are given medicines called corticosteroids during pregnancy. These medicines can speed up surfactant production and lung development in a fetus. Even if you had these medicines, your infant may still need surfactant replacement therapy after birth. Breathing Support Infants who have RDS often need breathing support until their lungs start making enough surfactant. Until recently, a mechanical ventilator usually was used. The ventilator was connected to a breathing tube that ran through the infant's mouth or nose into the windpipe. Today, more and more infants are receiving breathing support from NCPAP. NCPAP gently pushes air into the baby's lungs through prongs placed in the infant's nostrils. Oxygen Therapy Infants who have breathing problems may get oxygen therapy. Oxygen is given through a ventilator or NCPAP machine, or through a tube in the nose. This treatment ensures that the infants' organs get enough oxygen to work well. For more information, go to the Health Topics Oxygen Therapy article. Other Treatments Other treatments for RDS include medicines, supportive therapy, and treatment for patent ductus arteriosus (PDA). PDA is a condition that affects some premature infants. Medicines Doctors often give antibiotics to infants who have RDS to control infections (if the doctors suspect that an infant has an infection). Supportive Therapy Treatment in the NICU helps limit stress on babies and meet their basic needs of warmth, nutrition, and protection. Such treatment may include: Using a radiant warmer or incubator to keep infants warm and reduce the risk of infection. Ongoing monitoring of blood pressure, heart rate, breathing, and temperature through sensors taped to the babies' bodies. Using sensors on fingers or toes to check the amount of oxygen in the infants' blood. Giving fluids and nutrients through needles or tubes inserted into the infants' veins. This helps prevent malnutrition and promotes growth. Nutrition is critical to the growth and development of the lungs. Later, babies may be given breast milk or infant formula through feeding tubes that are passed through their noses or mouths and into their throats. Checking fluid intake to make sure that fluid doesn't build up in the babies' lungs. Treatment for Patent Ductus Arteriosus PDA is a possible complication of RDS. In this condition, a fetal blood vessel called the ductus arteriosus doesn't close after birth as it should. The ductus arteriosus connects a lung artery to a heart artery. If it remains open, it can strain the heart and increase blood pressure in the lung arteries. PDA is treated with medicines, catheter procedures, and surgery. For more information, go to the Health Topics Patent Ductus Arteriosus article.
How to prevent Respiratory Distress Syndrome ?
Taking steps to ensure a healthy pregnancy might prevent your infant from being born before his or her lungs have fully developed. These steps include: Seeing your doctor regularly during your pregnancy Following a healthy diet Avoiding tobacco smoke, alcohol, and illegal drugs Managing any medical conditions you have Preventing infections If you're having a planned cesarean delivery (C-section), your doctor can do tests before delivery to show whether it's likely that your baby's lungs are fully developed. These tests assess the age of the fetus or lung maturity. Your doctor may give you injections of a corticosteroid medicine if he or she thinks you may give birth too early. This medicine can speed up surfactant production and development of the lungs, brain, and kidneys in your baby. Treatment with corticosteroids can reduce your baby's risk of respiratory distress syndrome (RDS). If the baby does develop RDS, it will probably be fairly mild. Corticosteroid treatment also can reduce the chances that your baby will have bleeding in the brain.
What is (are) Vasculitis ?
Vasculitis (vas-kyu-LI-tis) is a condition that involves inflammation in the blood vessels. The condition occurs if your immune system attacks your blood vessels by mistake. This may happen as the result of an infection, a medicine, or another disease or condition. Inflammation refers to the bodys response to injury, including injury to the blood vessels. Inflammation may involve pain, redness, warmth, swelling, and loss of function in the affected tissues. In vasculitis, inflammation can lead to serious problems. Complications depend on which blood vessels, organs, or other body systems are affected. Overview Vasculitis can affect any of the body's blood vessels. These include arteries, veins, and capillaries. Arteries carry blood from your heart to your body's organs. Veins carry blood from your organs and limbs back to your heart. Capillaries connect the small arteries and veins. If a blood vessel is inflamed, it can narrow or close off. This limits or prevents blood flow through the vessel. Rarely, the blood vessel will stretch and weaken, causing it to bulge. This bulge is known as an aneurysm (AN-u-rism). Vasculitis The disruption in blood flow caused by inflammation can damage the body's organs. Signs and symptoms depend on which organs have been damaged and the extent of the damage. Typical symptoms of inflammation, such as fever and general aches and pains, are common among people who have vasculitis. Outlook There are many types of vasculitis, but overall the condition is rare. If you have vasculitis, the outlook depends on: The type of vasculitis you have Which organs are affected How quickly the condition worsens The severity of the condition Treatment often works well if its started early. In some cases, vasculitis may go into remission. "Remission" means the condition isn't active, but it can come back, or "flare," at any time. Sometimes vasculitis is chronic (ongoing) and never goes into remission. Long-term treatment with medicines often can control the signs and symptoms of chronic vasculitis. Rarely, vasculitis doesn't respond well to treatment. This can lead to disability and even death. Much is still unknown about vasculitis. However, researchers continue to learn more about the condition and its various types, causes, and treatments.
What causes Vasculitis ?
Vasculitis occurs if your immune system attacks your blood vessels by mistake. What causes this to happen isn't fully known. A recent or chronic (ongoing) infection may prompt the attack. Your body also may attack its own blood vessels in reaction to a medicine. Sometimes an autoimmune disorder triggers vasculitis. Autoimmune disorders occur if the immune system makes antibodies (proteins) that attack and damage the body's own tissues or cells. Examples of these disorders include lupus, rheumatoid arthritis, and scleroderma. You can have these disorders for years before developing vasculitis. Vasculitis also may be linked to certain blood cancers, such as leukemia and lymphoma.
Who is at risk for Vasculitis? ?
Vasculitis can affect people of all ages and races and both sexes. Some types of vasculitis seem to occur more often in people who: Have certain medical conditions, such as chronic hepatitis B or C infection Have certain autoimmune diseases, such a lupus, rheumatoid arthritis, and scleroderma Smoke For more information, go to "Types of Vasculitis."
What are the symptoms of Vasculitis ?
The signs and symptoms of vasculitis vary. They depend on the type of vasculitis you have, the organs involved, and the severity of the condition. Some people may have few signs and symptoms. Other people may become very sick. Sometimes the signs and symptoms develop slowly, over months. Other times, the signs and symptoms develop quickly, over days or weeks. Systemic Signs and Symptoms Systemic signs and symptoms are those that affect you in a general or overall way. Common systemic signs and symptoms of vasculitis are: Fever Loss of appetite Weight loss Fatigue (tiredness) General aches and pains Organ- or Body System-Specific Signs and Symptoms Vasculitis can affect specific organs and body systems, causing a range of signs and symptoms. Skin If vasculitis affects your skin, you may notice skin changes. For example, you may have purple or red spots or bumps, clusters of small dots, splotches, bruises, or hives. Your skin also may itch. Joints If vasculitis affects your joints, you may ache or develop arthritis in one or more joints. Lungs If vasculitis affects your lungs, you may feel short of breath. You may even cough up blood. The results from a chest x ray may show signs that suggest pneumonia, even though that may not be what you have. Gastrointestinal Tract If vasculitis affects your gastrointestinal tract, you may get ulcers (sores) in your mouth or have stomach pain. In severe cases, blood flow to the intestines can be blocked. This can cause the wall of the intestines to weaken and possibly rupture (burst). A rupture can lead to serious problems or even death. Sinuses, Nose, Throat, and Ears If vasculitis affects your sinuses, nose, throat, and ears, you may have sinus or chronic (ongoing) middle ear infections. Other symptoms include ulcers in the nose and, in some cases, hearing loss. Eyes If vasculitis affects your eyes, you may develop red, itchy, burning eyes. Your eyes also may become sensitive to light, and your vision may blur. Rarely, certain types of vasculitis may cause blindness. Brain If vasculitis affects your brain, symptoms may include headaches, problems thinking clearly, changes in mental function, or stroke-like symptoms, such as muscle weakness and paralysis (an inability to move). Nerves If vasculitis affects your nerves, you may have numbness, tingling, and weakness in various parts of your body. You also may have a loss of feeling or strength in your hands and feet and shooting pains in your arms and legs.
How to diagnose Vasculitis ?
Your doctor will diagnose vasculitis based on your signs and symptoms, your medical history, a physical exam, and test results. Specialists Involved Depending on the type of vasculitis you have and the organs affected, your doctor may refer you to various specialists, including: A rheumatologist (joint and muscle specialist) An infectious disease specialist A dermatologist (skin specialist) A pulmonologist (lung specialist) A nephrologist (kidney specialist) A neurologist (nervous system specialist) A cardiologist (heart specialist) An ophthalmologist (eye specialist) A urologist (urinary tract and urogenital system specialist) Diagnostic Tests and Procedures Many tests are used to diagnose vasculitis. Blood Tests Blood tests can show whether you have abnormal levels of certain blood cells and antibodies (proteins) in your blood. These tests may look at: Hemoglobin and hematocrit. A low hemoglobin or hematocrit level suggests anemia, a complication of vasculitis. Vasculitis can interfere with the body's ability to make enough red blood cells. Vasculitis also can be linked to increased destruction of red blood cells. Antineutrophil cytoplasmic antibodies (ANCA). These antibodies are present in people who have certain types of vasculitis. Erythrocyte sedimentation rate (ESR). A high ESR may be a sign of inflammation in the body. The amount of C-reactive protein (CRP) in your blood. A high CRP level suggests inflammation. Biopsy A biopsy often is the best way for your doctor to make a firm diagnosis of vasculitis. During a biopsy, your doctor will take a small sample of your body tissue to study under a microscope. He or she will take the tissue sample from a blood vessel or an organ. A pathologist will study the sample for signs of inflammation or tissue damage. A pathologist is a doctor who specializes in identifying diseases by studying cells and tissues under a microscope. Blood Pressure People who have vasculitis should have their blood pressure checked routinely. Vasculitis that damages the kidneys can cause high blood pressure. Urinalysis For this test, you'll provide a urine sample for analysis. This test detects abnormal levels of protein or blood cells in the urine. Abnormal levels of these substances can be a sign of vasculitis affecting the kidneys. EKG (Electrocardiogram) An EKG is a simple, painless test that records the heart's electrical activity. You might have this test to show whether vasculitis is affecting your heart. Echocardiography Echocardiography is a painless test that uses sound waves to create a moving picture of your heart. The test gives information about the size and shape of your heart and how well your heart chambers and valves are working. Chest X Ray A chest x ray is a painless test that creates pictures of the structures inside your chest, such as your heart, lungs, and blood vessels. Abnormal chest x-ray results may show whether vasculitis is affecting your lungs or your large arteries (such as the aorta or the pulmonary arteries). Lung Function Tests Lung function tests measure how much air you can breathe in and out, how fast you can breathe air out, and how well your lungs deliver oxygen to your blood. Lung function tests can help your doctor find out whether airflow into and out of your lungs is restricted or blocked. Abdominal Ultrasound An abdominal ultrasound uses sound waves to create a picture of the organs and structures in your abdomen. The picture may show whether vasculitis is affecting your abdominal organs. Computed Tomography Scan A computed tomography (to-MOG-rah-fee) scan, or CT scan, is a type of x ray that creates more detailed pictures of your internal organs than a standard x ray. The results from this test can show whether you have a type of vasculitis that affects your abdominal organs or blood vessels. Magnetic Resonance Imaging A magnetic resonance imaging (MRI) test uses radio waves, magnets, and a computer to create detailed pictures of your internal organs. Other Advanced Imaging Techniques Several new imaging techniques are now being used to help diagnose vasculitis. Duplex ultrasonography combines an image of the structure of the blood vessel with a color image of the blood flow through that vein or artery. 18F-fluorodeoxyglucose positron emission tomography (FDG-PET) identifies areas that show higher glucose metabolism leading to problems in the blood vessels. Angiography Angiography (an-jee-OG-ra-fee) is a test that uses dye and special x rays to show blood flowing through your blood vessels. The dye is injected into your bloodstream. Special x-ray pictures are taken while the dye flows through your blood vessels. The dye helps highlight the vessels on the x-ray pictures. Doctors use angiography to help find out whether blood vessels are narrowed, swollen, deformed, or blocked.
What are the treatments for Vasculitis ?
Treatment for vasculitis will depend on the type of vasculitis you have, which organs are affected, and the severity of the condition. People who have severe vasculitis are treated with prescription medicines. Rarely, surgery may be done. People who have mild vasculitis may find relief with over-the-counter pain medicines, such as acetaminophen, aspirin, ibuprofen, or naproxen. The main goal of treating vasculitis is to reduce inflammation in the affected blood vessels. This usually is done by reducing or stopping the immune response that caused the inflammation. Types of Treatment Common prescription medicines used to treat vasculitis include corticosteroids and cytotoxic medicines. Corticosteroids help reduce inflammation in your blood vessels. Examples of corticosteroids are prednisone, prednisolone, and methylprednisolone. Doctors may prescribe cytotoxic medicines if vasculitis is severe or if corticosteroids don't work well. Cytotoxic medicines kill the cells that are causing the inflammation. Examples of these medicines are azathioprine, methotrexate, and cyclophosphamide. Your doctor may prescribe both corticosteroids and cytotoxic medicines. Other treatments may be used for certain types of vasculitis. For example, the standard treatment for Kawasaki disease is high-dose aspirin and immune globulin. Immune globulin is a medicine thats injected into a vein. Certain types of vasculitis may require surgery to remove aneurysms that have formed as a result of the condition. (An aneurysm is an abnormal bulge in the wall of a blood vessel.)
How to prevent Vasculitis ?
You can't prevent vasculitis. However, treatment can help prevent or delay the complications of vasculitis. People who have severe vasculitis are treated with prescription medicines. Rarely, surgery may be done. People who have mild vasculitis may find relief with over-the-counter pain medicines, such as acetaminophen, aspirin, ibuprofen, or naproxen. For more information about vasculitis treatments, go to "How Is Vasculitis Treated?"
What is (are) Alpha-1 Antitrypsin Deficiency ?
Alpha-1 antitrypsin (an-tee-TRIP-sin) deficiency, or AAT deficiency, is a condition that raises your risk for lung disease (especially if you smoke) and other diseases. Some people who have severe AAT deficiency develop emphysema (em-fi-SE-ma)often when they're only in their forties or fifties. Emphysema is a serious lung disease in which damage to the airways makes it hard to breathe. A small number of people who have AAT deficiency develop cirrhosis (sir-RO-sis) and other serious liver diseases. Cirrhosis is a disease in which the liver becomes scarred. The scarring prevents the organ from working well. In people who have AAT deficiency, cirrhosis and other liver diseases usually occur in infancy and early childhood. A very small number of people who have AAT deficiency have a rare skin disease called necrotizing panniculitis (pa-NIK-yu-LI-tis). This disease can cause painful lumps under or on the surface of the skin. This article focuses on AAT deficiency as it relates to lung disease. Overview Alpha-1 antitrypsin, also called AAT, is a protein made in the liver. Normally, the protein travels through the bloodstream. It helps protect the body's organs from the harmful effects of other proteins. The lungs are one of the main organs that the AAT protein protects. AAT deficiency occurs if the AAT proteins made in the liver aren't the right shape. They get stuck inside liver cells and can't get into the bloodstream. As a result, not enough AAT proteins travel to the lungs to protect them. This increases the risk of lung disease. Also, because too many AAT proteins are stuck in the liver, liver disease can develop. Severe AAT deficiency occurs if blood levels of the AAT protein fall below the lowest amount needed to protect the lungs. AAT deficiency is an inherited condition. "Inherited" means it's passed from parents to children through genes. Doctors don't know how many people have AAT deficiency. Many people who have the condition may not know they have it. Estimates of how many people have AAT deficiency range from about 1 in every 1,600 people to about 1 in every 5,000 people. Outlook People who have AAT deficiency may not have serious complications, and they may live close to a normal lifespan. Among people with AAT deficiency who have a related lung or liver disease, about 3percent die each year. Smoking is the leading risk factor for life-threatening lung disease if you have AAT deficiency. Smoking or exposure to tobacco smoke increases the risk of earlier lung-related symptoms and lung damage. If you have severe AAT deficiency, smoking can shorten your life by as much as 20 years. AAT deficiency has no cure, but treatments are available. Treatments often are based on the type of disease you develop.
What causes Alpha-1 Antitrypsin Deficiency ?
Alpha-1 antitrypsin (AAT) deficiency is an inherited disease. "Inherited" means it's passed from parents to children through genes. Children who have AAT deficiency inherit two faulty AAT genes, one from each parent. These genes tell cells in the body how to make AAT proteins. In AAT deficiency, the AAT proteins made in the liver aren't the right shape. Thus, they get stuck in the liver cells. The proteins can't get to the organs in the body that they protect, such as the lungs. Without the AAT proteins protecting the organs, diseases can develop. The most common faulty gene that can cause AAT deficiency is called PiZ. If you inherit two PiZ genes (one from each parent), you'll have AAT deficiency. If you inherit a PiZ gene from one parent and a normal AAT gene from the other parent, you won't have AAT deficiency. However, you might pass the PiZ gene to your children. Even if you inherit two faulty AAT genes, you may not have any related complications. You may never even realize that you have AAT deficiency.
Who is at risk for Alpha-1 Antitrypsin Deficiency? ?
Alpha-1 antitrypsin (AAT) deficiency occurs in all ethnic groups. However, the condition occurs most often in White people of European descent. AAT deficiency is an inherited condition. "Inherited" means the condition is passed from parents to children through genes. If you have bloodline relatives with known AAT deficiency, you're at increased risk for the condition. Even so, it doesn't mean that you'll develop one of the diseases related to the condition. Some risk factors make it more likely that you'll develop lung disease if you have AAT deficiency. Smoking is the leading risk factor for serious lung disease if you have AAT deficiency. Your risk for lung disease also may go up if you're exposed to dust, fumes, or other toxic substances.
What are the symptoms of Alpha-1 Antitrypsin Deficiency ?
The first lung-related symptoms of alpha-1 antitrypsin (AAT) deficiency may include shortness of breath, less ability to be physically active, and wheezing. These signs and symptoms most often begin between the ages of 20 and 40. Other signs and symptoms may include repeated lung infections, tiredness, a rapid heartbeat upon standing, vision problems, and weight loss. Some people who have severe AAT deficiency develop emphysema (em-fi-SE-ma)often when they're only in their forties or fifties. Signs and symptoms of emphysema include problems breathing, wheezing, and a chronic (ongoing) cough. At first, many people who have AAT deficiency are diagnosed with asthma. This is because wheezing also is a symptom of asthma. Also, people who have AAT deficiency respond well to asthma medicines.
How to diagnose Alpha-1 Antitrypsin Deficiency ?
Alpha-1 antitrypsin (AAT) deficiency usually is diagnosed after you develop a lung or liver disease that's related to the condition. Your doctor may suspect AAT deficiency if you have signs or symptoms of a serious lung condition, especially emphysema, without any obvious cause. He or she also may suspect AAT deficiency if you develop emphysema when you're 45 years old or younger. Specialists Involved Many doctors may be involved in the diagnosis of AAT deficiency. These include primary care doctors, pulmonologists (lung specialists), and hepatologists (liver specialists). To diagnose AAT deficiency, your doctor will: Ask about possible risk factors. Risk factors include smoking and exposure to dust, fumes, and other toxic substances. Ask about your medical history. A common sign of AAT deficiency is if you have a lung or liver disease without any obvious causes or risk factors. Another sign is if you have emphysema at an unusually early age (45 years or younger). Ask about your family's medical history. If you have bloodline relatives who have AAT deficiency, you're more likely to have the condition. Diagnostic Tests Your doctor may recommend tests to confirm a diagnosis of AAT deficiency. He or she also may recommend tests to check for lung- or liver-related conditions. A genetic test is the most certain way to check for AAT deficiency. This test will show whether you have faulty AAT genes. A blood test also may be used. This test checks the level of AAT protein in your blood. If the level is a lot lower than normal, it's likely that you have AAT deficiency. Lung-Related Tests If you have a lung disease related to AAT deficiency, your doctor may recommend lung function tests and high-resolution computed tomography (to-MOG-rah-fee) scanning, also called CT scanning. Lung function tests measure how much air you can breathe in and out, how fast you can breathe air out, and how well your lungs deliver oxygen to your blood. These tests may show how severe your lung disease is and how well treatment is working. High-resolution CT scanning uses x rays to create detailed pictures of parts of the body. A CT scan can show whether you have emphysema or another lung disease and how severe it is.
What are the treatments for Alpha-1 Antitrypsin Deficiency ?
Alpha-1 antitrypsin (AAT) deficiency has no cure, but its related lung diseases have many treatments. Most of these treatments are the same as the ones used for a lung disease called COPD (chronic obstructive pulmonary disease). If you have symptoms related to AAT deficiency, your doctor may recommend: Medicines called inhaled bronchodilators (brong-ko-di-LA-tors) and inhaled steroids. These medicines help open your airways and make breathing easier. They also are used to treat asthma and COPD. Flu and pneumococcal (noo-mo-KOK-al) vaccines to protect you from illnesses that could make your condition worse. Prompt treatment of lung infections also can help protect your lungs. Pulmonary rehabilitation (rehab). Rehab involves treatment by a team of experts at a special clinic. In rehab, you'll learn how to manage your condition and function at your best. Extra oxygen, if needed. A lung transplant. A lung transplant may be an option if you have severe breathing problems. If you have a good chance of surviving the transplant surgery, you may be a candidate for it. Augmentation (og-men-TA-shun) therapy is a treatment used only for people who have AAT-related lung diseases. This therapy involves getting infusions of the AAT protein. The infusions raise the level of the protein in your blood and lungs. Not enough research has been done to show how well this therapy works. However, some research suggests that this therapy may slow the development of AAT deficiency in people who don't have severe disease. People who have AAT deficiency and develop related liver or skin diseases will be referred to doctors who treat those diseases. Future Treatments Researchers are working on possible treatments that will target the faulty AAT genes and replace them with healthy genes. These treatments are in the early stages of development. Researchers also are studying therapies that will help misshapen AAT proteins move from the liver into the bloodstream. They're also studying a type of augmentation therapy in which the AAT protein is inhaled instead of injected into a vein. If you're interested in new treatments, ask your doctor about ongoing clinical trials for AAT deficiency.
How to prevent Alpha-1 Antitrypsin Deficiency ?
You can't prevent alpha-1 antitrypsin (AAT) deficiency because the condition is inherited (passed from parents to children through genes). If you inherit two faulty AAT genes, you'll have AAT deficiency. Even so, you may never develop one of the diseases related to the condition. You can take steps to prevent or delay lung diseases related to AAT deficiency. One important step is to quit smoking. If you don't smoke, don't start. Talk with your doctor about programs and products that can help you quit smoking. If you have trouble quitting smoking on your own, consider joining a support group. Many hospitals, workplaces, and community groups offer classes to help people quit smoking. For more information about how to quit smoking, go to the Health Topics Smoking and Your Heart article and the National Heart, Lung, and Blood Institute's "Your Guide to a Healthy Heart." Although these resources focus on heart health, they include basic information about how to quit smoking. Also, try to avoid secondhand smoke and places with dust, fumes, or other toxic substances that you may inhale. Check your living and working spaces for things that may irritate your lungs. Examples include flower and tree pollen, ash, allergens, air pollution, wood burning stoves, paint fumes, and fumes from cleaning products and other household items. If you have a lung disease related to AAT deficiency, ask your doctor whether you might benefit from augmentation therapy. This is a treatment in which you receive infusions of AAT protein. Augmentation therapy raises the level of AAT protein in your blood and lungs. (For more information, go to "How Is Alpha-1 Antitrypsin Deficiency Treated?")
What is (are) Holes in the Heart ?
Holes in the heart are simple congenital (kon-JEN-ih-tal) heart defects. Congenital heart defects are problems with the heart's structure that are present at birth. These defects change the normal flow of blood through the heart. The heart has two sides, separated by an inner wall called the septum. With each heartbeat, the right side of the heart receives oxygen-poor blood from the body and pumps it to the lungs. The left side of the heart receives oxygen-rich blood from the lungs and pumps it to the body. The septum prevents mixing of blood between the two sides of the heart. However, some babies are born with holes in the upper or lower septum. A hole in the septum between the heart's two upper chambers is called an atrial septal defect (ASD). A hole in the septum between the heart's two lower chambers is called a ventricular septal defect (VSD). ASDs and VSDs allow blood to pass from the left side of the heart to the right side. Thus, oxygen-rich blood mixes with oxygen-poor blood. As a result, some oxygen-rich blood is pumped to the lungs instead of the body. Over the past few decades, the diagnosis and treatment of ASDs and VSDs have greatly improved. Children who have simple congenital heart defects can survive to adulthood. They can live normal, active lives because their heart defects close on their own or have been repaired.
What causes Holes in the Heart ?
Mothers of children who are born with atrial septal defects (ASDs), ventricular septal defects (VSDs), or other heart defects may think they did something wrong during their pregnancies. However, most of the time, doctors don't know why congenital heart defects occur. Heredity may play a role in some heart defects. For example, a parent who has a congenital heart defect is slightly more likely than other people to have a child who has the problem. Very rarely, more than one child in a family is born with a heart defect. Children who have genetic disorders, such as Down syndrome, often have congenital heart defects. Half of all babies who have Down syndrome have congenital heart defects. Smoking during pregnancy also has been linked to several congenital heart defects, including septal defects. Scientists continue to search for the causes of congenital heart defects.
What are the symptoms of Holes in the Heart ?
Atrial Septal Defect Many babies who are born with atrial septal defects (ASDs) have no signs or symptoms. However, as they grow, these children may be small for their age. When signs and symptoms do occur, a heart murmur is the most common. A heart murmur is an extra or unusual sound heard during a heartbeat. Often, a heart murmur is the only sign of an ASD. However, not all murmurs are signs of congenital heart defects. Many healthy children have heart murmurs. Doctors can listen to heart murmurs and tell whether they're harmless or signs of heart problems. If a large ASD isn't repaired, the extra blood flow to the right side of the heart can damage the heart and lungs and cause heart failure. This generally doesn't occur until adulthood. Signs and symptoms of heart failure include: Fatigue (tiredness) Tiring easily during physical activity Shortness of breath A buildup of blood and fluid in the lungs Swelling in the ankles, feet, legs, abdomen, and veins in the neck Ventricular Septal Defect Babies born with ventricular septal defects (VSDs) usually have heart murmurs. Murmurs may be the first and only sign of a VSD. Heart murmurs often are present right after birth in many infants. However, the murmurs may not be heard until the babies are 6 to 8 weeks old. Most newborns who have VSDs don't have heart-related symptoms. However, babies who have medium or large VSDs can develop heart failure. Signs and symptoms of heart failure usually occur during the baby's first 2 months of life. The signs and symptoms of heart failure due to VSD are similar to those listed above for ASD, but they occur in infancy. A major sign of heart failure in infancy is poor feeding and growth. VSD signs and symptoms are rare after infancy. This is because the defects either decrease in size on their own or they're repaired.
How to diagnose Holes in the Heart ?
Doctors usually diagnose holes in the heart based on a physical exam and the results from tests and procedures. The exam findings for an atrial septal defect (ASD) often aren't obvious. Thus, the diagnosis sometimes isn't made until later in childhood or even in adulthood. Ventricular septal defects (VSDs) cause a very distinct heart murmur. Because of this, a diagnosis usually is made in infancy. Specialists Involved Doctors who specialize in diagnosing and treating heart problems are called cardiologists. Pediatric cardiologists take care of babies and children who have heart problems. Cardiac surgeons repair heart defects using surgery. Physical Exam During a physical exam, your child's doctor will listen to your child's heart and lungs with a stethoscope. The doctor also will look for signs of a heart defect, such as a heart murmur or signs of heart failure. Diagnostic Tests and Procedures Your child's doctor may recommend several tests to diagnose an ASD or VSD. These tests also will help the doctor figure out the location and size of the defect. Echocardiography Echocardiography (echo) is a painless test that uses sound waves to create a moving picture of the heart. The sound waves (called ultrasound) bounce off the structures of the heart. A computer converts the sound waves into pictures on a screen. Echo allows the doctor to clearly see any problem with the way the heart is formed or the way it's working. Echo is an important test for both diagnosing a hole in the heart and following the problem over time. Echo can show problems with the heart's structure and how the heart is reacting to the problems. This test will help your child's cardiologist decide whether and when treatment is needed. EKG (Electrocardiogram) An EKG is a simple, painless test that records the heart's electrical activity. The test shows how fast the heart is beating and its rhythm (steady or irregular). It also records the strength and timing of electrical signals as they pass through the heart. An EKG can detect whether one of the heart's chambers is enlarged, which can help diagnose a heart problem. Chest X Ray A chest x ray is a painless test that creates pictures of the structures in the chest, such as the heart, lungs, and blood vessels. This test can show whether the heart is enlarged. A chest x ray also can show whether the lungs have extra blood flow or extra fluid, a sign of heart failure. Pulse Oximetry Pulse oximetry shows the level of oxygen in the blood. A small sensor is attached to a finger or ear. The sensor uses light to estimate how much oxygen is in the blood. Cardiac Catheterization During cardiac catheterization (KATH-e-ter-i-ZA-shun), a thin, flexible tube called a catheter is put into a vein in the arm, groin (upper thigh), or neck. The tube is threaded to the heart. Special dye is injected through the catheter into a blood vessel or one of the heart's chambers. The dye allows the doctor to see the flow of blood through the heart and blood vessels on an x-ray image. The doctor also can use cardiac catheterization to measure the pressure inside the heart chambers and blood vessels. This can help the doctor figure out whether blood is mixing between the two sides of the heart. Doctors also use cardiac catheterization to repair some heart defects. For more information, go to "How Are Holes in the Heart Treated?"
What are the treatments for Holes in the Heart ?
Many holes in the heart don't need treatment, but some do. Those that do often are repaired during infancy or early childhood. Sometimes adults are treated for holes in the heart if problems develop. The treatment your child receives depends on the type, location, and size of the hole. Other factors include your child's age, size, and general health. Treating an Atrial Septal Defect If a child has an atrial septal defect (ASD), routine checkups are done to see whether it closes on its own. About half of all ASDs close on their own over time, and about 20 percent close within the first year of life. Your child's doctor will let you know how often your child should have checkups. For an ASD, frequent checkups aren't needed. If an ASD requires treatment, catheter or surgical procedures are used to close the hole. Doctors often decide to close ASDs in children who still have medium- or large-sized holes by the time they're 2 to 5 years old. Catheter Procedure Until the early 1990s, surgery was the usual method for closing all ASDs. Now, thanks to medical advances, doctors can use catheter procedures to close secundum ASDs. These are the most common type of ASD. Before a catheter procedure, your child is given medicine so he or she will sleep and not feel any pain. Then, the doctor inserts a catheter (a thin, flexible tube) into a vein in the groin (upper thigh). He or she threads the tube to the heart's septum. A device made up of two small disks or an umbrella-like device is attached to the catheter. When the catheter reaches the septum, the device is pushed out of the catheter. The device is placed so that it plugs the hole between the atria. It's secured in place and the catheter is withdrawn from the body. Within 6 months, normal tissue grows in and over the device. The closure device does not need to be replaced as the child grows. Doctors often use echocardiography (echo), transesophageal (tranz-ih-sof-uh-JEE-ul) echo (TEE), and coronary angiography (an-jee-OG-rah-fee) to guide them in threading the catheter to the heart and closing the defect. TEE is a special type of echo that takes pictures of the heart through the esophagus. The esophagus is the passage leading from the mouth to the stomach. Catheter procedures are much easier on patients than surgery. They involve only a needle puncture in the skin where the catheter is inserted. This means that recovery is faster and easier. The outlook for children having this procedure is excellent. Closures are successful in more than 9 out of 10 patients, with no major leakage. Rarely, a defect is too large for catheter closure and surgery is needed. Surgery Open-heart surgery generally is done to repair primum or sinus venosus ASDs. Before the surgery, your child is given medicine so he or she will sleep and not feel any pain. Then, the cardiac surgeon makes an incision (cut) in the chest to reach the ASD. He or she repairs the defect with a special patch that covers the hole. A heart-lung bypass machine is used during the surgery so the surgeon can open the heart. The machine takes over the heart's pumping action and moves blood away from the heart. The outlook for children who have ASD surgery is excellent. On average, children spend 3 to 4 days in the hospital before going home. Complications, such as bleeding and infection, are very rare. In some children, the outer lining of the heart may become inflamed. This condition is called pericarditis (PER-i-kar-DI-tis). The inflammation causes fluid to collect around the heart in the weeks after surgery. Medicine usually can treat this condition. While in the hospital, your child will be given medicine as needed to reduce pain or anxiety. The doctors and nurses at the hospital will teach you how to care for your child at home. They will talk about preventing blows to the chest as the incision heals, limiting activity while your child recovers, bathing, scheduling ongoing care, and deciding when your child can go back to his or her regular activities. Treating a Ventricular Septal Defect Doctors may choose to monitor children who have ventricular septal defects (VSDs) but no symptoms of heart failure. This means regular checkups and tests to see whether the defect closes on its own or gets smaller. More than half of VSDs eventually close, usually by the time children are in preschool. Your child's doctor will let you know how often your child needs checkups. Checkups may range from once a month to once every 1 or 2 years. If treatment for a VSD is required, options include extra nutrition and surgery to close the VSD. Doctors also can use catheter procedures to close some VSDs. They may use this approach if surgery isn't possible or doesn't work. More research is needed to find out the risks and benefits of using catheter procedures to treat VSDs. Extra Nutrition Some infants who have VSDs don't grow and develop or gain weight as they should. These infants usually: Have large VSDs Are born too early Tire easily during feeding Doctors usually recommend extra nutrition or special feedings for these infants. These feedings are high-calorie formulas or breast milk supplements that give babies extra nourishment. Some infants need tube feeding. A small tube is inserted into the mouth and moved down into the stomach. Food is given through the tube. Tube feeding can add to or take the place of bottle feeding. This treatment often is short-term because a VSD that causes symptoms will likely require surgery. Surgery Most doctors recommend surgery to close large VSDs that are causing symptoms, affecting the aortic valve, or haven't closed by the time children are 1 year old. Surgery may be needed earlier if: A child doesn't gain weight Medicines are needed to control the symptoms of heart failure Rarely, medium-sized VSDs that are causing enlarged heart chambers are treated with surgery after infancy. However, most VSDs that require surgery are repaired in the first year of life. Doctors use open-heart surgery and patches to close VSDs.
What is (are) Atherosclerosis ?
Espaol Atherosclerosis is a disease in which plaque builds up inside your arteries. Arteries are blood vessels that carry oxygen-rich blood to your heart and other parts of your body. Plaque is made up of fat, cholesterol, calcium, and other substances found in the blood. Over time, plaque hardens and narrows your arteries. This limits the flow of oxygen-rich blood to your organs and other parts of your body. Atherosclerosis can lead to serious problems, including heart attack, stroke, or even death. Atherosclerosis Atherosclerosis-Related Diseases Atherosclerosis can affect any artery in the body, including arteries in the heart, brain, arms, legs, pelvis, and kidneys. As a result, different diseases may develop based on which arteries are affected. Coronary Heart Disease Coronary heart disease (CHD), also called coronary artery disease, occurs when plaque builds up in the coronary arteries. These arteries supply oxygen-rich blood to your heart. Plaque narrows the coronary arteries and reduces blood flow to your heart muscle. Plaque buildup also makes it more likely that blood clots will form in your arteries. Blood clots can partially or completely block blood flow. If blood flow to your heart muscle is reduced or blocked, you may have angina (chest pain or discomfort) or a heart attack. Plaque also can form in the heart's smallest arteries. This disease is called coronary microvascular disease (MVD). In coronary MVD, plaque doesn't cause blockages in the arteries as it does in CHD. Carotid Artery Disease Carotid (ka-ROT-id) artery disease occurs if plaque builds up in the arteries on each side of your neck (the carotid arteries). These arteries supply oxygen-rich blood to your brain. If blood flow to your brain is reduced or blocked, you may have a stroke. Peripheral Artery Disease Peripheral artery disease (P.A.D.) occurs if plaque builds up in the major arteries that supply oxygen-rich blood to your legs, arms, and pelvis. If blood flow to these parts of your body is reduced or blocked, you may have numbness, pain, and, sometimes, dangerous infections. Chronic Kidney Disease Chronic kidney disease can occur if plaque builds up in the renal arteries. These arteries supply oxygen-rich blood to your kidneys. Over time, chronic kidney disease causes a slow loss of kidney function. The main function of the kidneys is to remove waste and extra water from the body. Overview The cause of atherosclerosis isn't known. However, certain traits, conditions, or habits may raise your risk for the disease. These conditions are known as risk factors. You can control some risk factors, such as lack of physical activity, smoking, and an unhealthy diet. Others you can't control, such as age and a family history of heart disease. Some people who have atherosclerosis have no signs or symptoms. They may not be diagnosed until after a heart attack or stroke. The main treatment for atherosclerosis is lifestyle changes. You also may need medicines and medical procedures. These treatments, along with ongoing medical care, can help you live a healthier life. Outlook Improved treatments have reduced the number of deaths from atherosclerosis-related diseases. These treatments also have improved the quality of life for people who have these diseases. However, atherosclerosis remains a common health problem. You may be able to prevent or delay atherosclerosis and the diseases it can cause. Making lifestyle changes and getting ongoing care can help you avoid the problems of atherosclerosis and live a long, healthy life.
What causes Atherosclerosis ?
The exact cause of atherosclerosis isn't known. However, studies show that atherosclerosis is a slow, complex disease that may start in childhood. It develops faster as you age. Atherosclerosis may start when certain factors damage the inner layers of the arteries. These factors include: Smoking High amounts of certain fats and cholesterol in the blood High blood pressure High amounts of sugar in the blood due to insulin resistance or diabetes Plaque may begin to build up where the arteries are damaged. Over time, plaque hardens and narrows the arteries. Eventually, an area of plaque can rupture (break open). When this happens, blood cell fragments called platelets (PLATE-lets) stick to the site of the injury. They may clump together to form blood clots. Clots narrow the arteries even more, limiting the flow of oxygen-rich blood to your body. Depending on which arteries are affected, blood clots can worsen angina (chest pain) or cause a heart attack or stroke. Researchers continue to look for the causes of atherosclerosis. They hope to find answers to questions such as: Why and how do the arteries become damaged? How does plaque develop and change over time? Why does plaque rupture and lead to blood clots?
Who is at risk for Atherosclerosis? ?
The exact cause of atherosclerosis isn't known. However, certain traits, conditions, or habits may raise your risk for the disease. These conditions are known as risk factors. The more risk factors you have, the more likely it is that you'll develop atherosclerosis. You can control most risk factors and help prevent or delay atherosclerosis. Other risk factors can't be controlled. Major Risk Factors Unhealthy blood cholesterol levels. This includes high LDL cholesterol (sometimes called "bad" cholesterol) and low HDL cholesterol (sometimes called "good" cholesterol). High blood pressure. Blood pressure is considered high if it stays at or above 140/90 mmHg over time. If you have diabetes or chronic kidney disease, high blood pressure is defined as 130/80 mmHg or higher. (The mmHg is millimeters of mercurythe units used to measure blood pressure.) Smoking. Smoking can damage and tighten blood vessels, raise cholesterol levels, and raise blood pressure. Smoking also doesn't allow enough oxygen to reach the body's tissues. Insulin resistance. This condition occurs if the body can't use its insulin properly. Insulin is a hormone that helps move blood sugar into cells where it's used as an energy source. Insulin resistance may lead to diabetes. Diabetes. With this disease, the body's blood sugar level is too high because the body doesn't make enough insulin or doesn't use its insulin properly. Overweight or obesity. The terms "overweight" and "obesity" refer to body weight that's greater than what is considered healthy for a certain height. Lack of physical activity. A lack of physical activity can worsen other risk factors for atherosclerosis, such as unhealthy blood cholesterol levels, high blood pressure, diabetes, and overweight and obesity. Unhealthy diet. An unhealthy diet can raise your risk for atherosclerosis. Foods that are high in saturated and trans fats, cholesterol, sodium (salt), and sugar can worsen other atherosclerosis risk factors. Older age. As you get older, your risk for atherosclerosis increases. Genetic or lifestyle factors cause plaque to build up in your arteries as you age. By the time you're middle-aged or older, enough plaque has built up to cause signs or symptoms. In men, the risk increases after age 45. In women, the risk increases after age 55. Family history of early heart disease. Your risk for atherosclerosis increases if your father or a brother was diagnosed with heart disease before 55 years of age, or if your mother or a sister was diagnosed with heart disease before 65 years of age. Although age and a family history of early heart disease are risk factors, it doesn't mean that you'll develop atherosclerosis if you have one or both. Controlling other risk factors often can lessen genetic influences and prevent atherosclerosis, even in older adults. Studies show that an increasing number of children and youth are at risk for atherosclerosis. This is due to a number of causes, including rising childhood obesity rates. Emerging Risk Factors Scientists continue to study other possible risk factors for atherosclerosis. High levels of a protein called C-reactive protein (CRP) in the blood may raise the risk for atherosclerosis and heart attack. High levels of CRP are a sign of inflammation in the body. Inflammation is the body's response to injury or infection. Damage to the arteries' inner walls seems to trigger inflammation and help plaque grow. People who have low CRP levels may develop atherosclerosis at a slower rate than people who have high CRP levels. Research is under way to find out whether reducing inflammation and lowering CRP levels also can reduce the risk for atherosclerosis. High levels of triglycerides (tri-GLIH-seh-rides) in the blood also may raise the risk for atherosclerosis, especially in women. Triglycerides are a type of fat. Studies are under way to find out whether genetics may play a role in atherosclerosis risk. Other Factors That Affect Atherosclerosis Other factors also may raise your risk for atherosclerosis, such as: Sleep apnea. Sleep apnea is a disorder that causes one or more pauses in breathing or shallow breaths while you sleep. Untreated sleep apnea can raise your risk for high blood pressure, diabetes, and even a heart attack or stroke. Stress. Research shows that the most commonly reported "trigger" for a heart attack is an emotionally upsetting event, especially one involving anger. Alcohol. Heavy drinking can damage the heart muscle and worsen other risk factors for atherosclerosis. Men should have no more than two drinks containing alcohol a day. Women should have no more than one drink containing alcohol a day.
What are the symptoms of Atherosclerosis ?
Atherosclerosis usually doesn't cause signs and symptoms until it severely narrows or totally blocks an artery. Many people don't know they have the disease until they have a medical emergency, such as a heart attack or stroke. Some people may have signs and symptoms of the disease. Signs and symptoms will depend on which arteries are affected. Coronary Arteries The coronary arteries supply oxygen-rich blood to your heart. If plaque narrows or blocks these arteries (a disease called coronary heart disease, or CHD), a common symptom is angina. Angina is chest pain or discomfort that occurs when your heart muscle doesn't get enough oxygen-rich blood. Angina may feel like pressure or squeezing in your chest. You also may feel it in your shoulders, arms, neck, jaw, or back. Angina pain may even feel like indigestion. The pain tends to get worse with activity and go away with rest. Emotional stress also can trigger the pain. Other symptoms of CHD are shortness of breath and arrhythmias (ah-RITH-me-ahs). Arrhythmias are problems with the rate or rhythm of the heartbeat. Plaque also can form in the heart's smallest arteries. This disease is called coronary microvascular disease (MVD). Symptoms of coronary MVD include angina, shortness of breath, sleep problems, fatigue (tiredness), and lack of energy. Carotid Arteries The carotid arteries supply oxygen-rich blood to your brain. If plaque narrows or blocks these arteries (a disease called carotid artery disease), you may have symptoms of a stroke. These symptoms may include: Sudden weakness Paralysis (an inability to move) or numbness of the face, arms, or legs, especially on one side of the body Confusion Trouble speaking or understanding speech Trouble seeing in one or both eyes Problems breathing Dizziness, trouble walking, loss of balance or coordination, and unexplained falls Loss of consciousness Sudden and severe headache Peripheral Arteries Plaque also can build up in the major arteries that supply oxygen-rich blood to the legs, arms, and pelvis (a disease calledperipheral artery disease). If these major arteries are narrowed or blocked, you may have numbness, pain, and, sometimes, dangerous infections. Renal Arteries The renal arteries supply oxygen-rich blood to your kidneys. If plaque builds up in these arteries, you may develop chronic kidney disease. Over time, chronic kidney disease causes a slow loss of kidney function. Early kidney disease often has no signs or symptoms. As the disease gets worse it can cause tiredness, changes in how you urinate (more often or less often), loss of appetite, nausea (feeling sick to the stomach), swelling in the hands or feet, itchiness or numbness, and trouble concentrating.
How to diagnose Atherosclerosis ?
Your doctor will diagnose atherosclerosis based on your medical and family histories, a physical exam, and test results. Specialists Involved If you have atherosclerosis, a primary care doctor, such as an internist or family practitioner, may handle your care. Your doctor may recommend other health care specialists if you need expert care, such as: A cardiologist. This is a doctor who specializes in diagnosing and treating heart diseases and conditions. You may go to a cardiologist if you haveperipheral artery disease(P.A.D.)or coronary microvascular disease (MVD). A vascular specialist. This is a doctor who specializes in diagnosing and treating blood vessel problems. You may go to a vascular specialist if you have P.A.D. A neurologist. This is a doctor who specializes in diagnosing and treating nervous system disorders. You may see a neurologist if you've had a stroke due to carotid artery disease. A nephrologist. This is a doctor who specializes in diagnosing and treating kidney diseases and conditions. You may go to a nephrologist if you have chronic kidney disease. Physical Exam During the physical exam, your doctor may listen to your arteries for an abnormal whooshing sound called a bruit (broo-E). Your doctor can hear a bruit when placing a stethoscope over an affected artery. A bruit may indicate poor blood flow due to plaque buildup. Your doctor also may check to see whether any of your pulses (for example, in the leg or foot) are weak or absent. A weak or absent pulse can be a sign of a blocked artery. Diagnostic Tests Your doctor may recommend one or more tests to diagnose atherosclerosis. These tests also can help your doctor learn the extent of your disease and plan the best treatment. Blood Tests Blood tests check the levels of certain fats, cholesterol, sugar, and proteins in your blood. Abnormal levels may be a sign that you're at risk for atherosclerosis. EKG (Electrocardiogram) An EKG is a simple, painless test that detects and records the heart's electrical activity. The test shows how fast the heart is beating and its rhythm (steady or irregular). An EKG also records the strength and timing of electrical signals as they pass through the heart. An EKG can show signs of heart damage caused by CHD. The test also can show signs of a previous or current heart attack. Chest X Ray A chest x ray takes pictures of the organs and structures inside your chest, such as your heart, lungs, and blood vessels. A chest x ray can reveal signs of heart failure. Ankle/Brachial Index This test compares the blood pressure in your ankle with the blood pressure in your arm to see how well your blood is flowing. This test can help diagnose P.A.D. Echocardiography Echocardiography (echo) uses sound waves to create a moving picture of your heart. The test provides information about the size and shape of your heart and how well your heart chambers and valves are working. Echo also can identify areas of poor blood flow to the heart, areas of heart muscle that aren't contracting normally, and previous injury to the heart muscle caused by poor blood flow. Computed Tomography Scan A computed tomography (CT) scan creates computer-generated pictures of the heart, brain, or other areas of the body. The test can show hardening and narrowing of large arteries. A cardiac CT scan also can show whether calcium has built up in the walls of the coronary (heart) arteries. This may be an early sign of CHD. Stress Testing During stress testing, you exercise to make your heart work hard and beat fast while heart tests are done. If you can't exercise, you may be given medicine to make your heart work hard and beat fast. When your heart is working hard, it needs more blood and oxygen. Plaque-narrowed arteries can't supply enough oxygen-rich blood to meet your heart's needs. A stress test can show possible signs and symptoms of CHD, such as: Abnormal changes in your heart rate or blood pressure Shortness of breath or chest pain Abnormal changes in your heart rhythm or your heart's electrical activity As part of some stress tests, pictures are taken of your heart while you exercise and while you rest. These imaging stress tests can show how well blood is flowing in various parts of your heart. They also can show how well your heart pumps blood when it beats. Angiography Angiography (an-jee-OG-ra-fee) is a test that uses dye and special x rays to show the inside of your arteries. This test can show whether plaque is blocking your arteries and how severe the blockage is. A thin, flexible tube called a catheter is put into a blood vessel in your arm, groin (upper thigh), or neck. Dye that can be seen on an x-ray picture is injected through the catheter into the arteries. By looking at the x-ray picture, your doctor can see the flow of blood through your arteries. Other Tests Other tests are being studied to see whether they can give a better view of plaque buildup in the arteries. Examples of these tests include magnetic resonance imaging (MRI) and positron emission tomography (PET).
What are the treatments for Atherosclerosis ?
Treatments for atherosclerosis may include heart-healthy lifestyle changes, medicines, and medical procedures or surgery. The goals of treatment include: Lowering the risk of blood clots forming Preventing atherosclerosis-related diseases Reducing risk factors in an effort to slow or stop the buildup of plaque Relieving symptoms Widening or bypassing plaque-clogged arteries Heart-Healthy Lifestyle Changes Your doctor may recommend heart-healthy lifestyle changes if you have atherosclerosis. Heart-healthy lifestyle changes include heart-healthy eating, maintaining a healthy weight, managing stress, physical activity and quitting smoking. Heart-Healthy Eating Your doctor may recommend heart-healthy eating, which should include: Fat-free or low-fat dairy products, such as skim milk Fish high in omega-3 fatty acids, such as salmon, tuna, and trout, about twice a week Fruits, such as apples, bananas, oranges, pears, and prunes Legumes, such as kidney beans, lentils, chickpeas, black-eyed peas, and lima beans Vegetables, such as broccoli, cabbage, and carrots Whole grains, such as oatmeal, brown rice, and corn tortillas When following a heart-healthy diet, you should avoid eating: A lot of red meat Palm and coconut oils Sugary foods and beverages Two nutrients in your diet make blood cholesterol levels rise: Saturated fatfound mostly in foods that come from animals Trans fat (trans fatty acids)found in foods made with hydrogenated oils and fats, such as stick margarine; baked goods, such as cookies, cakes, and pies; crackers; frostings; and coffee creamers. Some trans fats also occur naturally in animal fats and meats. Saturated fat raises your blood cholesterol more than anything else in your diet. When you follow a heart-healthy eating plan, only 5 percent to 6 percent of your daily calories should come from saturated fat. Food labels list the amounts of saturated fat. To help you stay on track, here are some examples: 1,200 calories a day 8 grams of saturated fat a day 1,500 calories a day 10 grams of saturated fat a day 1,800 calories a day 12 grams of saturated fat a day 2,000 calories a day 13 grams of saturated fat a day 2,500 calories a day 17 grams of saturated fat a day Not all fats are bad. Monounsaturated and polyunsaturated fats actually help lower blood cholesterol levels. Some sources of monounsaturated and polyunsaturated fats are: Avocados Corn, sunflower, and soybean oils Nuts and seeds, such as walnuts Olive, canola, peanut, safflower, and sesame oils Peanut butter Salmon and trout Tofu Sodium You should try to limit the amount of sodium that you eat. This means choosing and preparing foods that are lower in salt and sodium. Try to use low-sodium and no added salt foods and seasonings at the table or while cooking. Food labels tell you what you need to know about choosing foods that are lower in sodium. Try to eat no more than 2,300 milligrams of sodium a day. If you have high blood pressure, you may need to restrict your sodium intake even more. Dietary Approaches to Stop Hypertension Your doctor may recommend the Dietary Approaches to Stop Hypertension (DASH) eating plan if you have high blood pressure. The DASH eating plan focuses on fruits, vegetables, whole grains, and other foods that are heart healthy and low in fat, cholesterol, and sodium and salt. The DASH eating plan is a good heart-healthy eating plan, even for those who dont have high blood pressure. Read more about DASH. Alcohol Try to limit alcohol intake. Too much alcohol will raise your blood pressure and triglyceride levels, a type of fat found in the blood. Alcohol also adds extra calories, which may cause weight gain. Men should have no more than two drinks containing alcohol a day. Women should have no more than one drink containing alcohol a day. One drink is: 12 ounces of beer 5 ounces of wine 1 ounces of liquor Maintaining a Healthy Weight Maintaining a healthy weight is important for overall health and can lower your risk for coronary heart disease. Aim for a Healthy Weight by following a heart-healthy eating plan and keeping physically active. Knowing your body mass index (BMI) helps you find out if youre a healthy weight in relation to your height and gives an estimate of your total body fat. To figure out your BMI, check out the National Heart, Lung, and Blood Institutes online BMI calculator or talk to your doctor. A BMI: Below 18.5 is a sign that you are underweight. Between 18.5 and 24.9 is in the normal range. Between 25.0 and 29.9 is considered overweight. A BMI of 30.0 or higher is considered obese. A general goal to aim for is a BMI of less than 25. Your doctor or health care provider can help you set an appropriate BMI goal. Measuring waist circumference helps screen for possible health risks. If most of your fat is around your waist rather than at your hips, youre at a higher risk for heart disease and type2 diabetes. This risk may be high with a waist size that is greater than 35 inches for women or greater than 40 inches for men. To learn how to measure your waist, visit Assessing Your Weight and Health Risk. For more information about losing weight or maintaining your weight, visit Aim for a Healthy Weight. If youre overweight or obese, try to lose weight. A loss of just 3 percent to 5 percent of your current weight can lower your triglycerides, blood glucose, and the risk of developing type 2 diabetes. Greater amounts of weight loss can improve blood pressure readings, lower LDL cholesterol, and increase HDL cholesterol. Managing Stress Learning how to manage stress, relax, and cope with problems can improve your emotional and physical health. Consider healthy stress-reducing activities, such as: A stress management program Meditation Physical activity Relaxation therapy Talking things out with friends or family Physical Activity Regular physical activity can lower many atherosclerosis risk factors, including LDL or bad cholesterol, high blood pressure, and excess weight. Physical activity also can lower your risk for diabetes and raise your HDL or good cholesterol, which helps prevent atherosclerosis. Everyone should try to participate in moderate-intensity aerobic exercise at least 2 hours and 30 minutes per week or vigorous aerobic exercise for 1 hour and 15 minutes per week. Aerobic exercise, such as brisk walking, is any exercise in which your heart beats faster and you use more oxygen than usual. The more active you are, the more you will benefit. Participate in aerobic exercise for at least 10minutes at a time spread throughout the week. Talk with your doctor before you start a new exercise plan. Ask your doctor how much and what kinds of physical activity are safe for you. Read more about physical activity at: Physical Activity and Your Heart U.S. Department of Health and Human Services, 2008 Physical Activity Guidelines for Americans Quitting Smoking If you smoke or use tobacco, quit. Smoking can damage and tighten blood vessels and raise your risk for atherosclerosis. Talk with your doctor about programs and products that can help you quit. Also, try to avoid secondhand smoke. If you have trouble quitting smoking on your own, consider joining a support group. Many hospitals, workplaces, and community groups offer classes to help people quit smoking. For more information about how to quit smoking, visit Smoking and Your Heart. Medicines Sometimes lifestyle changes alone arent enough to control your cholesterol levels. For example, you also may need statin medications to control or lower your cholesterol. By lowering your blood cholesterol level, you can decrease your chance of having a heart attack or stroke. Doctors usually prescribe statins for people who have: Coronary heart disease, peripheral artery disease, or had a prior stroke Diabetes High LDL cholesterol levels Doctors may discuss beginning statin treatment with people who have an elevated risk for developing heart disease or having a stroke. Your doctor also may prescribe other medications to: Lower your blood pressure Lower your blood sugar levels Prevent blood clots, which can lead to heart attack and stroke Prevent inflammation Take all medicines regularly, as your doctor prescribes. Dont change the amount of your medicine or skip a dose unless your doctor tells you to. You should still follow a heart healthy lifestyle, even if you take medicines to treat your atherosclerosis. Medical Procedures and Surgery If you have severe atherosclerosis, your doctor may recommend a medical procedure or surgery. Percutaneous coronary intervention (PCI), also known as coronary angioplasty, is a procedure thats used to open blocked or narrowed coronary (heart) arteries. PCI can improve blood flow to the heart and relieve chest pain. Sometimes a small mesh tube called a stent is placed in the artery to keep it open after the procedure. Coronary artery bypass grafting (CABG) is a type of surgery. In CABG, arteries or veins from other areas in your body are used to bypass or go around your narrowed coronary arteries. CABG can improve blood flow to your heart, relieve chest pain, and possibly prevent a heart attack. Bypass grafting also can be used for leg arteries. For this surgery, a healthy blood vessel is used to bypass a narrowed or blocked artery in one of the legs. The healthy blood vessel redirects blood around the blocked artery, improving blood flow to the leg. Carotid endarterectomy is a type of surgery to remove plaque buildup from the carotid arteries in the neck. This procedure restores blood flow to the brain, which can help prevent a stroke.
How to prevent Atherosclerosis ?
Taking action to control your risk factors can help prevent or delay atherosclerosis and its related diseases. Your risk for atherosclerosis increases with the number of risk factors youhave. One step you can take is to adopt a healthy lifestyle, which can include: Heart-Healthy Eating. Adopt heart-healthy eating habits, which include eating different fruits and vegetables (including beans and peas), whole grains, lean meats, poultry without skin, seafood, and fat-free or low-fat milk and dairy products. A heart-healthy diet is low in sodium, added sugar, solid fats, and refined grains. Following a heart-healthy diet is an important part of a healthy lifestyle. Physical Activity. Be as physically active as you can. Physical activity can improve your fitness level and your health. Ask your doctor what types and amounts of activity are safe for you. Read more about Physical Activity and Your Heart. Quit Smoking. If you smoke, quit. Smoking can damage and tighten blood vessels and raise your risk for atherosclerosis. Talk with your doctor about programs and products that can help you quit. Also, try to avoid secondhand smoke. Read more about Smoking and Your Heart. Weight Control. If youre overweight or obese, work with your doctor to create a reasonable weight-loss plan. Controlling your weight helps you control risk factors foratherosclerosis. Other steps that can prevent or delay atherosclerosis include knowing your family history of atherosclerosis. If you or someone in your family has an atherosclerosis-related disease, be sure to tell your doctor. If lifestyle changes arent enough, your doctor may prescribe medicines to control your atherosclerosis risk factors. Take all of your medicines as your doctor advises.
What is (are) Kawasaki Disease ?
Kawasaki (KAH-wah-SAH-ke) disease is a rare childhood disease. It's a form of a condition calledvasculitis(vas-kyu-LI-tis). This condition involves inflammation of the blood vessels. In Kawasaki disease, the walls of the blood vessels throughout the body become inflamed. The disease can affect any type of blood vessel in the body, including the arteries, veins, and capillaries. Sometimes Kawasaki disease affects the coronary arteries, which carry oxygen-rich blood to the heart. As a result, some children who have Kawasaki disease may develop serious heart problems. Overview The cause of Kawasaki disease isn't known. The body's response to a virus or infection combined with genetic factors may cause the disease. However, no specific virus or infection has been found, and the role of genetics isn't known. The disease can't be passed from one child to another. Your child won't get it from close contact with a child who has the disease. Also, if your child has the disease, he or she can't pass it to another child. Kawasaki disease affects children of all races and ages and both genders. It occurs most often in children of Asian and Pacific Island descent. The disease is more likely to affect boys than girls. Most cases occur in children younger than 5years old. One of the main symptoms of Kawasaki disease is a fever that lasts longer than5days. The fever remains high even after treatment with standard childhood fever medicines. Children who have the disease also may have red eyes, red lips, and redness on the palms of their hands and soles of their feet. These are all signs of inflamed blood vessels. Early treatment helps reduce the risk of Kawasaki disease affecting the coronary arteries and causing serious problems. Outlook Kawasaki disease can't be prevented. However, most children who have the disease usually recover within weeks of getting symptoms. Further problems are rare. The disease affects some children's coronary arteries, which can cause serious problems. These children need long-term care and treatment. Researchers continue to look for the cause of Kawasaki disease and better ways to diagnose and treat it. They also hope to learn more about long-term health risks, if any, for people who have had the disease.
What causes Kawasaki Disease ?
The cause of Kawasaki disease isn't known. The body's response to a virus or infection combined with genetic factors may cause the disease. However, no specific virus or infection has been found, and the role of genetics isn't known. Kawasaki disease can't be passed from one child to another. Your child won't get it from close contact with a child who has the disease. Also, if your child has the disease, he or she can't pass it to another child.
Who is at risk for Kawasaki Disease? ?
Kawasaki disease affects children of all races and ages and both genders. It occurs most often in children of Asian and Pacific Island descent. The disease is more likely to affect boys than girls. Most cases occur in children younger than 5 years old. Kawasaki disease is rare in children older than 8.
What are the symptoms of Kawasaki Disease ?
Major Signs and Symptoms One of the main symptoms during the early part of Kawasaki disease, called the acute phase, is fever. The fever lasts longer than 5 days. It remains high even after treatment with standard childhood fever medicines. Other classic signs of the disease are: Swollen lymph nodes in the neck A rash on the mid-section of the body and in the genital area Red, dry, cracked lips and a red, swollen tongue Red, swollen palms of the hands and soles of the feet Redness of the eyes Other Signs and Symptoms During the acute phase, your child also may be irritable and have a sore throat, joint pain, diarrhea, vomiting, and stomach pain. Within 2 to 3 weeks of the start of symptoms, the skin on your child's fingers and toes may peel, sometimes in large sheets.
How to diagnose Kawasaki Disease ?
Kawasaki disease is diagnosed based on your child's signs and symptoms and the results from tests and procedures. Specialists Involved Pediatricians often are the first to suspect a child has Kawasaki disease. Pediatricians are doctors who specialize in treating children. If the disease has affected your child's coronary (heart) arteries, a pediatric cardiologist will confirm the diagnosis and give ongoing treatment. Pediatric cardiologists treat children who have heart problems. Other specialists also may be involved in treating children who have Kawasaki disease. Signs and Symptoms The doctor will check your child for the classic signs and symptoms of Kawasaki disease. The doctor will rule out other diseases that cause similar symptoms. These diseases include Rocky Mountain spotted fever, scarlet fever, and juvenile rheumatoid arthritis. Generally, your child will be diagnosed with Kawasaki disease if he or she has a fever that lasts longer than 5 days plus four other classic signs or symptoms of the disease. However, not all children have classic signs and symptoms of Kawasaki disease. Tests and procedures can help confirm whether a child has the disease. Tests and Procedures Echocardiography If the doctor thinks that your child has Kawasaki disease, he or she will likely recommendechocardiography(EK-o-kar-de-OG-ra-fee), or echo. This painless test uses sound waves to create pictures of the heart and coronary arteries. Echo also can help show the disease's effects over time, if any, on your child's coronary arteries. Often, the disease's effects on the coronary arteries don't show up until the second or third week after the first symptoms appear. Thus, this test is done regularly after the diagnosis. Some children who have Kawasaki disease don't have the classic signs and symptoms of the acute phase. Doctors may not diagnose these children until 2 to 3 weeks after the onset of the disease. This is when another common sign of Kawasaki disease occurspeeling of the skin on the fingers and toes. If your child is diagnosed at this point, he or she will likely need echo right away to see whether the disease has affected the coronary arteries. Other Diagnostic Tests Doctors also use other tests to help diagnose Kawasaki disease, such as: Blood tests. The results from blood tests can show whether the body's blood vessels are inflamed. Chest x ray. This painless test creates pictures of structures inside the chest, such as the heart and lungs. A chest x ray can show whether Kawasaki disease has affected the heart. EKG (electrocardiogram). This simple test detects and records the heart's electrical activity. An EKG can show whether Kawasaki disease has affected the heart.
What are the treatments for Kawasaki Disease ?
Medicines are the main treatment for Kawasaki disease. Rarely, children whose coronary (heart) arteries are affected may need medical procedures or surgery. The goals of treatment include: Reducing fever and inflammation to improve symptoms Preventing the disease from affecting the coronary arteries Initial Treatment Kawasaki disease can cause serious health problems. Thus, your child will likely be treated in a hospital, at least for the early part of treatment. The standard treatment during the disease's acute phase is high-dose aspirin and immune globulin. Immune globulin is a medicine that's injected into a vein. Most children who receive these treatments improve greatly within 24 hours. For a small number of children, fever remains. These children may need a second round of immune globulin. At the start of treatment, your child will receive high doses of aspirin. As soon as his or her fever goes away, a low dose of aspirin is given. The low dose helps prevent blood clots, which can form in the inflamed small arteries. Most children treated for Kawasaki disease fully recover from the acute phase and don't need any further treatment. They should, however, follow a healthy diet and adopt healthy lifestyle habits. Taking these steps can help lower the risk of future heart disease. (Following a healthy lifestyle is advised for all children, not just those who have Kawasaki disease.) Children who have had immune globulin should wait 11 months before having the measles and chicken pox vaccines. Immune globulin can prevent those vaccines from working well. Long-Term Care and Treatment If Kawasaki disease has affected your child's coronary arteries, he or she will need ongoing care and treatment. It's best if a pediatric cardiologist provides this care to reduce the risk of severe heart problems. A pediatric cardiologist is a doctor who specializes in treating children who have heart problems. Medicines and Tests When Kawasaki disease affects the coronary arteries, they may expand and twist. If this happens, your child's doctor may prescribe blood-thinning medicines (for example, warfarin). These medicines help prevent blood clots from forming in the affected coronary arteries. Blood-thinning medicines usually are stopped after the coronary arteries heal. Healing may occur about 18 months after the acute phase of the disease. In a small number of children, the coronary arteries don't heal. These children likely will need routine tests, such as: Echocardiography. This test uses sound waves to create images of the heart. EKG (electrocardiogram). This test detects and records the heart's electrical activity. Stress test. This test provides information about how the heart works during physical activity or stress. Medical Procedures and Surgery Rarely, a child who has Kawasaki disease may needcardiac catheterization(KATH-eh-ter-ih-ZA-shun). Doctors use this procedure to diagnose and treat some heart conditions. A flexible tube called a catheter is put into a blood vessel in the arm, groin (upper thigh), or neck and threaded to the heart. Through the catheter, doctors can perform tests and treatments on the heart. Very rarely, a child may need to have other procedures or surgery if inflammation narrows his or her coronary arteries and blocks blood flow to the heart. Percutaneous coronary intervention (PCI), stent placement, or coronary artery bypass grafting(CABG) may be used. Coronary angioplasty restores blood flow through narrowed or blocked coronary arteries. A thin tube with a balloon on the end is inserted into a blood vessel in the arm or groin. The tube is threaded to the narrowed or blocked coronary artery. Then, the balloon is inflated to widen the artery and restore blood flow. A stent (small mesh tube) may be placed in the coronary artery during angioplasty. This device helps support the narrowed or weakened artery. A stent can improve blood flow and prevent the artery from bursting. Rarely, a child may need to have CABG. This surgery is used to treat blocked coronary arteries. During CABG, a healthy artery or vein from another part of the body is connected, or grafted, to the blocked coronary artery. The grafted artery or vein bypasses (that is, goes around) the blocked part of the coronary artery. This improves blood flow to the heart.
How to prevent Kawasaki Disease ?
Kawasaki disease can't be prevented. However, most children who have the disease recoverusually within weeks of getting signs and symptoms. Further problems are rare.
What is (are) ARDS ?
ARDS, or acute respiratory distress syndrome, is a lung condition that leads to low oxygen levels in the blood. ARDS can be life threatening because your body's organs need oxygen-rich blood to work well. People who develop ARDS often are very ill with another disease or have major injuries. They might already be in the hospital when they develop ARDS. Overview To understand ARDS, it helps to understand how the lungs work. When you breathe, air passes through your nose and mouth into your windpipe. The air then travels to your lungs' air sacs. These sacs are called alveoli (al-VEE-uhl-eye). Small blood vessels called capillaries (KAP-ih-lare-ees) run through the walls of the air sacs. Oxygen passes from the air sacs into the capillaries and then into the bloodstream. Blood carries the oxygen to all parts of the body, including the body's organs. In ARDS, infections, injuries, or other conditions cause fluid to build up in the air sacs. This prevents the lungs from filling with air and moving enough oxygen into the bloodstream. As a result, the body's organs (such as the kidneys and brain) don't get the oxygen they need. Without oxygen, the organs may not work well or at all. People who develop ARDS often are in the hospital for other serious health problems. Rarely, people who aren't hospitalized have health problems that lead to ARDS, such as severe pneumonia. If you have trouble breathing, call your doctor right away. If you have severe shortness of breath, call 911. Outlook More people are surviving ARDS now than in the past. One likely reason for this is that treatment and care for the condition have improved. Survival rates for ARDS vary depending on age, the underlying cause of ARDS, associated illnesses, and other factors. Some people who survive recover completely. Others may have lasting damage to their lungs and other health problems. Researchers continue to look for new and better ways to treat ARDS.
What causes ARDS ?
Many conditions or factors can directly or indirectly injure the lungs and lead to ARDS. Some common ones are: Sepsis. This is a condition in which bacteria infect the bloodstream. Pneumonia. This is an infection in the lungs. Severe bleeding caused by an injury to the body. An injury to the chest or head, like a severe blow. Breathing in harmful fumes or smoke. Inhaling vomited stomach contents from the mouth. It's not clear why some very sick or seriously injured people develop ARDS and others don't. Researchers are trying to find out why ARDS develops and how to prevent it.
Who is at risk for ARDS? ?
People at risk for ARDS have a condition or illness that can directly or indirectly injure their lungs. Direct Lung Injury Conditions that can directly injure the lungs include: Pneumonia. This is an infection in the lungs. Breathing in harmful fumes or smoke. Inhaling vomited stomach contents from the mouth. Using a ventilator. This is a machine that helps people breathe; rarely, it can injure the lungs. Nearly drowning. Indirect Lung Injury Conditions that can indirectly injure the lungs include: Sepsis. This is a condition in which bacteria infect the bloodstream. Severe bleeding caused by an injury to the body or having many blood transfusions. An injury to the chest or head, such as a severe blow. Pancreatitis (PAN-kre-a-TI-tis). This is a condition in which the pancreas becomes irritated or infected. The pancreas is a gland that releases enzymes and hormones. Fat embolism (EM-bo-lizm). This is a condition in which fat blocks an artery. A physical injury, like a broken bone, can lead to a fat embolism. Drug reaction.
What are the symptoms of ARDS ?
The first signs and symptoms of ARDS are feeling like you can't get enough air into your lungs, rapid breathing, and a low blood oxygen level. Other signs and symptoms depend on the cause of ARDS. They may occur before ARDS develops. For example, if pneumonia is causing ARDS, you may have a cough and fever before you feel short of breath. Sometimes people who have ARDS develop signs and symptoms such as low blood pressure, confusion, and extreme tiredness. This may mean that the body's organs, such as the kidneys and heart, aren't getting enough oxygen-rich blood. People who develop ARDS often are in the hospital for other serious health problems. Rarely, people who aren't hospitalized have health problems that lead to ARDS, such as severe pneumonia. If you have trouble breathing, call your doctor right away. If you have severe shortness of breath, call 911. Complications From ARDS If you have ARDS, you can develop other medical problems while in the hospital. The most common problems are: Infections. Being in the hospital and lying down for a long time can put you at risk for infections, such as pneumonia. Being on a ventilator also puts you at higher risk for infections. A pneumothorax (collapsed lung). This is a condition in which air or gas collects in the space around the lungs. This can cause one or both lungs to collapse. The air pressure from a ventilator can cause this condition. Lung scarring. ARDS causes the lungs to become stiff (scarred). It also makes it hard for the lungs to expand and fill with air. Being on a ventilator also can cause lung scarring. Blood clots. Lying down for long periods can cause blood clots to form in your body. A blood clot that forms in a vein deep in your body is called a deep vein thrombosis. This type of blood clot can break off, travel through the bloodstream to the lungs, and block blood flow. This condition is called pulmonary embolism.
How to diagnose ARDS ?
Your doctor will diagnose ARDS based on your medical history, a physical exam, and test results. Medical History Your doctor will ask whether you have or have recently had conditions that could lead to ARDS. For a list of these conditions, go to "Who Is at Risk for ARDS?" Your doctor also will ask whether you have heart problems, such as heart failure. Heart failure can cause fluid to build up in your lungs. Physical Exam ARDS may cause abnormal breathing sounds, such as crackling. Your doctor will listen to your lungs with a stethoscope to hear these sounds. He or she also will listen to your heart and look for signs of extra fluid in other parts of your body. Extra fluid may mean you have heart or kidney problems. Your doctor will look for a bluish color on your skin and lips. A bluish color means your blood has a low level of oxygen. This is a possible sign of ARDS. Diagnostic Tests You may have ARDS or another condition that causes similar symptoms. To find out, your doctor may recommend one or more of the following tests. Initial Tests The first tests done are: An arterial blood gas test. This blood test measures the oxygen level in your blood using a sample of blood taken from an artery. A low blood oxygen level might be a sign of ARDS. Chest x ray. This test creates pictures of the structures in your chest, such as your heart, lungs, and blood vessels. A chest x ray can show whether you have extra fluid in your lungs. Blood tests, such as a complete blood count, blood chemistries, and blood cultures. These tests help find the cause of ARDS, such as an infection. A sputum culture. This test is used to study the spit you've coughed up from your lungs. A sputum culture can help find the cause of an infection. Other Tests Other tests used to diagnose ARDS include: Chest computed tomography (to-MOG-rah-fee) scan, or chest CT scan. This test uses a computer to create detailed pictures of your lungs. A chest CT scan may show lung problems, such as fluid in the lungs, signs of pneumonia, or a tumor. Heart tests that look for signs of heart failure. Heart failure is a condition in which the heart can't pump enough blood to meet the body's needs. This condition can cause fluid to build up in your lungs.
What are the treatments for ARDS ?
ARDS is treated in a hospital's intensive care unit. Current treatment approaches focus on improving blood oxygen levels and providing supportive care. Doctors also will try to pinpoint and treat the underlying cause of the condition. Oxygen Therapy One of the main goals of treating ARDS is to provide oxygen to your lungs and other organs (such as your brain and kidneys). Your organs need oxygen to work properly. Oxygen usually is given through nasal prongs or a mask that fits over your mouth and nose. However, if your oxygen level doesn't rise or it's still hard for you to breathe, your doctor will give you oxygen through a breathing tube. He or she will insert the flexible tube through your mouth or nose and into your windpipe. Before inserting the tube, your doctor will squirt or spray a liquid medicine into your throat (and possibly your nose) to make it numb. Your doctor also will give you medicine through an intravenous (IV) line in your bloodstream to make you sleepy and relaxed. The breathing tube will be connected to a machine that supports breathing (a ventilator). The ventilator will fill your lungs with oxygen-rich air. Your doctor will adjust the ventilator as needed to help your lungs get the right amount of oxygen. This also will help prevent injury to your lungs from the pressure of the ventilator. You'll use the breathing tube and ventilator until you can breathe on your own. If you need a ventilator for more than a few days, your doctor may do a tracheotomy (tra-ke-OT-o-me). This procedure involves making a small cut in your neck to create an opening to the windpipe. The opening is called a tracheostomy (TRA-ke-OS-to-me). Your doctor will place the breathing tube directly into the windpipe. The tube is then connected to the ventilator. For more information, go to the Health Topics Oxygen Therapy article. Supportive Care Supportive care refers to treatments that help relieve symptoms, prevent complications, or improve quality of life. Supportive approaches used to treat ARDS include: Medicines to help you relax, relieve discomfort, and treat pain. Ongoing monitoring of heart and lung function (including blood pressure and gas exchange). Nutritional support. People who have ARDS often suffer from malnutrition. Thus, extra nutrition may be given through a feeding tube. Treatment for infections. People who have ARDS are at higher risk for infections, such as pneumonia. Being on a ventilator also increases the risk of infections. Doctors use antibiotics to treat pneumonia and other infections. Prevention of blood clots. Lying down for long periods can cause blood clots to form in the deep veins of your body. These clots can travel to your lungs and block blood flow (a condition called pulmonary embolism). Blood-thinning medicines and other treatments, such as compression stocking (stockings that create gentle pressure up the leg), are used to prevent blood clots. Prevention of intestinal bleeding. People who receive long-term support from a ventilator are at increased risk of bleeding in the intestines. Medicines can reduce this risk. Fluids. You may be given fluids to improve blood flow through your body and to provide nutrition. Your doctor will make sure you get the right amount of fluids. Fluids usually are given through an IV line inserted into one of your blood vessels.
