Question: What are the symptoms of Bronchiectasis ?
Answer: The initial airway damage that leads to bronchiectasis often begins in childhood. However, signs and symptoms may not appear until months or even years after you start having repeated lung infections.
The most common signs and symptoms of bronchiectasis are:
A daily cough that occurs over months or years
Daily production of large amounts of sputum (spit). Sputum, which you cough up and spit out, may contain mucus (a slimy substance), trapped particles, and pus.
Shortness of breath and wheezing (a whistling sound when you breathe)
Chest pain
Clubbing (the flesh under your fingernails and toenails gets thicker)
If your doctor listens to your lungs with a stethoscope, he or she may hear abnormal lung sounds.
Over time, you may have more serious symptoms. You may cough up blood or bloody mucus and feel very tired. Children may lose weight or not grow at a normal rate.
Complications of Bronchiectasis
Severe bronchiectasis can lead to other serious health conditions, such as respiratory failure and atelectasis.
Respiratory failure is a condition in which not enough oxygen passes from your lungs into your blood. The condition also can occur if your lungs can't properly remove carbon dioxide (a waste gas) from your blood.
Respiratory failure can cause shortness of breath, rapid breathing, and air hunger (feeling like you can't breathe in enough air). In severe cases, signs and symptoms may include a bluish color on your skin, lips, and fingernails; confusion; and sleepiness.
Atelectasis is a condition in which one or more areas of your lungs collapse or don't inflate properly. As a result, you may feel short of breath. Your heart rate and breathing rate may increase, and your skin and lips may turn blue.
If bronchiectasis is so advanced that it affects all parts of your airways, it may cause heart failure. Heart failure is a condition in which the heart can't pump enough blood to meet the body's needs.
The most common signs and symptoms of heart failure are shortness of breath or trouble breathing, tiredness, and swelling in the ankles, feet, legs, abdomen, and veins in the neck.
Question: How to diagnose Bronchiectasis ?
Answer: Your doctor may suspect bronchiectasis if you have a daily cough that produces large amounts of sputum (spit).
To find out whether you have bronchiectasis, your doctor may recommend tests to:
Identify any underlying causes that require treatment
Rule out other causes of your symptoms
Find out how much your airways are damaged
Diagnostic Tests and Procedures
Chest CT Scan
A chest computed tomography (to-MOG-ra-fee) scan, or chest CT scan, is the most common test for diagnosing bronchiectasis.
This painless test creates precise pictures of your airways and other structures in your chest. A chest CT scan can show the extent and location of lung damage. This test gives more detailed pictures than a standard chest x ray.
Chest X Ray
This painless test creates pictures of the structures in your chest, such as your heart and lungs. A chest x ray can show areas of abnormal lung and thickened, irregular airway walls.
Other Tests
Your doctor may recommend other tests, such as:
Blood tests. These tests can show whether you have an underlying condition that can lead to bronchiectasis. Blood tests also can show whether you have an infection or low levels of certain infection-fighting blood cells.
A sputum culture. Lab tests can show whether a sample of your sputum contains bacteria (such as the bacteria that cause tuberculosis) or fungi.
Lung function tests. These 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 help show how much lung damage you have.
A sweat test or other tests for cystic fibrosis.
Bronchoscopy
If your bronchiectasis doesn't respond to treatment, your doctor may recommend bronchoscopy (bron-KOS-ko-pee). Doctors use this procedure to look inside the airways.
During bronchoscopy, a flexible tube with a light on the end is inserted through your nose or mouth into your airways. The tube is called a bronchoscope. It provides a video image of your airways. You'll be given medicine to numb your upper airway and help you relax during the procedure.
Bronchoscopy can show whether you have a blockage in your airways. The procedure also can show the source of any bleeding in your airways.
Question: How to prevent Bronchiectasis ?
Answer: To prevent bronchiectasis, it's important to prevent the lung infections and lung damage that can cause it.
Childhood vaccines for measles and whooping cough prevent infections related to these illnesses. These vaccines also reduce complications from these infections, such as bronchiectasis.
Avoiding toxic fumes, gases, smoke, and other harmful substances also can help protect your lungs.
Proper treatment of lung infections in children also may help preserve lung function and prevent lung damage that can lead to bronchiectasis.
Stay alert to keep children (and adults) from inhaling small objects (such as pieces of toys and food that might stick in a small airway). If you think you, your child, or someone else has inhaled a small object, seek prompt medical care.
In some cases, treating the underlying cause of bronchiectasis can slow or prevent its progression.
Question: What is (are) Coronary Microvascular Disease ?
Answer: Coronary microvascular disease (MVD) is heart disease that affects the tiny coronary (heart) arteries. In coronary MVD, the walls of the heart's tiny arteries are damaged or diseased.
Coronary MVD is different from traditional coronary heart disease (CHD), also called coronary artery disease. In CHD, a waxy substance called plaque (plak) builds up in the large coronary arteries.
Plaque narrows the heart's large arteries and reduces the flow of oxygen-rich blood to your heart muscle. The buildup of plaque also makes it more likely that blood clots will form in your arteries. Blood clots can mostly or completely block blood flow through a coronary artery.
In coronary MVD, however, the heart's tiny arteries are affected. Plaque doesn't create blockages in these vessels as it does in the heart's large arteries.
Coronary Microvascular Disease
Overview
Both men and women who have coronary microvascular disease often have diabetes or high blood pressure. Some people who have coronary microvascular disease may have inherited heart muscle diseases.
Diagnosing coronary microvascular disease has been a challenge for doctors. Standard tests used to diagnose coronary heart disease arent designed to detect coronary microvascular disease. More research is needed to find the best diagnostic tests and treatments for thedisease.
Outlook
Most of what is known about coronary MVD comes from the National Heart, Lung, and Blood Institute's Wise study (Women's Ischemia Syndrome Evaluation).
The WISE study started in 1996. The goal of the study was to learn more about how heart disease develops in women.
Currently, research is ongoing to learn more about the role of hormones in heart disease and to find better ways to diagnose coronary MVD.
Studies also are under way to learn more about the causes of coronary MVD, how to treat the disease, and the expected health outcomes for people with coronary MVD.
Question: What causes Coronary Microvascular Disease ?
Answer: The same risk factors that cause atherosclerosis may cause coronary microvascular disease. Atherosclerosis is a disease in which plaque builds up inside the arteries.
Risk factors for atherosclerosis include:
Diabetes. It is a disease in which the bodys blood sugar level is too high because the body doesnt make enough insulin or doesnt use its insulin properly.
Family history of early heart disease. Your risk of atherosclerosis increases if your father or a brother was diagnosed with heart disease before age 55, or if your mother or a sister was diagnosed with heart disease before age 65.
High blood pressure. Blood pressure is considered high if it stays at or above 140/90mmHg 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.)
Insulin resistance. This condition occurs if the body cant use its insulin properly. Insulin is a hormone that helps move blood sugar into cells where its used for energy. Overtime, insulin resistance can lead to diabetes.
Lack of physical activity. Physical inactivity can worsen some other risk factors for atherosclerosis, such as unhealthy blood cholesterol levels, high blood pressure, diabetes, and overweight or obesity.
Older age. As you age, your risk for atherosclerosis increases. The process of atherosclerosis begins in youth and typically progresses over many decades before disease develops.
Overweight and obesity. The terms overweight and obesity refer to body weight thats greater than what is considered healthy for a certain height.
Smoking. Smoking can damage and tighten blood vessels, lead to unhealthy cholesterol levels, and raise blood pressure. Smoking also doesnt allow enough oxygen to reach the bodys tissues.
Unhealthy blood cholesterol levels. This includes high LDL (bad) cholesterol and low HDL (good) cholesterol.
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 risk factors for atherosclerosis.
In women, coronary microvascular disease also may be linked to low estrogen levels occurring before or after menopause. Also, the disease may be linked to anemia or conditions that affect blood clotting. Anemia is thought to slow the growth of cells needed to repair damaged blood vessels.
Researchers continue to explore other possible causes of coronary microvascular disease.
Question: Who is at risk for Coronary Microvascular Disease? ?
Answer: Coronary microvascular disease can affect both men and women. However, women may be at risk for coronary microvascular disease if they have lower than normal levels of estrogen at any point in their adult lives. (This refers to the estrogen that the ovaries produce, not the estrogen used in hormone therapy.) Low estrogen levels before menopause can raise younger womens risk for the disease. Causes of low estrogen levels in younger women can be mental stress or a problem with the function of theovaries.
The causes of coronary microvascular disease and atherosclerosis are also considered risk factors for the disease.
Question: What are the symptoms of Coronary Microvascular Disease ?
Answer: The signs and symptoms of coronary microvascular disease (MVD) often differ from the signs and symptoms of traditional coronary heart disease (CHD).
Many women with coronary MVD have angina (an-JI-nuh or AN-juh-nuh). 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.
Angina also is a common symptom of CHD. However, the angina that occurs in coronary MVD may differ from the typical angina that occurs in CHD. In coronary MVD, the chest pain usually lasts longer than 10 minutes, and it can last longer than 30 minutes. Typical angina is more common in women older than 65.
Other signs and symptoms of coronary MVD are shortness of breath, sleep problems, fatigue (tiredness), and lack of energy.
Coronary MVD symptoms often are first noticed during routine daily activities (such as shopping, cooking, cleaning, and going to work) and times of mental stress. It's less likely that women will notice these symptoms during physical activity (such as jogging or walking fast).
This differs from CHD, in which symptoms often first appear while a person is being physically activesuch as while jogging, walking on a treadmill, or going up stairs.
Question: How to diagnose Coronary Microvascular Disease ?
Answer: Your doctor will diagnose coronary microvascular disease (MVD) based on your medical history, a physical exam, and test results. He or she will check to see whether you have any risk factors for heart disease.
For example, your doctor may measure your weight and height to check for overweight or obesity. He or she also may recommend tests for high blood cholesterol, metabolic syndrome, and diabetes.
Your doctor may ask you to describe any chest pain, including when it started and how it changed during physical activity or periods of stress. He or she also may ask about other symptoms, such as fatigue (tiredness), lack of energy, and shortness of breath. Women may be asked about their menopausal status.
Specialists Involved
Cardiologists and doctors who specialize in family and internal medicine might help diagnose and treat coronary MVD. Cardiologists are doctors who specialize in diagnosing and treating heart diseases and conditions.
Diagnostic Tests
The risk factors for coronary MVD and traditional coronary heart disease (CHD) often are the same. Thus, your doctor may recommend tests for CHD, such as:
Coronary angiography (an-jee-OG-rah-fee). This test uses dye and special x rays to show the insides of your coronary arteries. Coronary angiography can show plaque buildup in the large coronary arteries. This test often is done during a heart attack to help find blockages in the coronary arteries.
Stress testing. This test shows how blood flows through your heart during physical stress, such as exercise. Even if coronary angiography doesn't show plaque buildup in the large coronary arteries, a stress test may still show abnormal blood flow. This may be a sign of coronary MVD.
Cardiac MRI (magnetic resonance imaging) stress test. Doctors may use this test to evaluate people who have chest pain.
Unfortunately, standard tests for CHD aren't designed to detect coronary MVD. These tests look for blockages in the large coronary arteries. Coronary MVD affects the tiny coronary arteries.
If test results show that you don't have CHD, your doctor might still diagnose you with coronary MVD. This could happen if signs are present that not enough oxygen is reaching your heart's tiny arteries.
Coronary MVD symptoms often first occur during routine daily tasks. Thus, your doctor may ask you to fill out a questionnaire called the Duke Activity Status Index (DASI). The questionnaire will ask you how well you're able to do daily activities, such as shopping, cooking, and going to work.
The DASI results will help your doctor decide which kind of stress test you should have. The results also give your doctor information about how well blood is flowing through your coronary arteries.
Your doctor also may recommend blood tests, including a test for anemia. Anemia is thought to slow the growth of cells needed to repair damaged blood vessels.
Research is ongoing for better ways to detect and diagnose coronary MVD. Currently, researchers have not agreed on the best way to diagnose the disease.
Question: What are the treatments for Coronary Microvascular Disease ?
Answer: Relieving pain is one of the main goals of treating coronary microvascular disease (MVD). Treatments also are used to control risk factors and other symptoms. Treatments may include medicines, such as:
ACE inhibitors and beta blockers to lower blood pressure and decrease the hearts workload
Aspirin to help prevent blood clots or control inflammation
Nitroglycerin to relax blood vessels, improve blood flow to the heart muscle, and treat chest pain
Statin medicines to control or lower your blood cholesterol.
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.
If youre diagnosed with coronary MVD and also haveanemia, you may benefit from treatment for that condition. Anemia is thought to slow the growth of cells needed to repair damaged blood vessels.
If youre diagnosed with and treated for coronary MVD, you should get ongoing care from your doctor. Research is under way to find the best treatments for coronary MVD.
Question: What is (are) Pneumonia ?
Answer: Pneumonia (nu-MO-ne-ah) is an infection in one or both of the lungs. Many germssuch as bacteria, viruses, and fungican cause pneumonia.
The infection inflames your lungs' air sacs, which are called alveoli (al-VEE-uhl-eye). The air sacs may fill up with fluid or pus, causing symptoms such as a cough with phlegm (a slimy substance), fever, chills, and trouble breathing.
Overview
Pneumonia and its symptoms can vary from mild to severe. Many factors affect how serious pneumonia is, such as the type of germ causing the infection and your age and overall health.
Pneumonia tends to be more serious for:
Infants and young children.
Older adults (people 65 years or older).
People who have other health problems, such as heart failure, diabetes, or COPD (chronic obstructive pulmonary disease).
People who have weak immune systems as a result of diseases or other factors. Examples of these diseases and factors include HIV/AIDS, chemotherapy (a treatment for cancer), and an organ transplant or blood and marrow stem cell transplant.
Outlook
Pneumonia is common in the United States. Treatment for pneumonia depends on its cause, how severe your symptoms are, and your age and overall health. Many people can be treated at home, often with oral antibiotics.
Children usually start to feel better in 1 to 2 days. For adults, it usually takes 2 to 3 days. Anyone who has worsening symptoms should see a doctor.
People who have severe symptoms or underlying health problems may need treatment in a hospital. It may take 3 weeks or more before they can go back to their normal routines.
Fatigue (tiredness) from pneumonia can last for a month or more.
Question: Who is at risk for Pneumonia? ?
Answer: Pneumonia can affect people of all ages. However, two age groups are at greater risk of developing pneumonia:
Infants who are 2 years old or younger (because their immune systems are still developing during the first few years of life)
People who are 65 years old or older
Other conditions and factors also raise your risk for pneumonia. You're more likely to get pneumonia if you have a lung disease or other serious disease. Examples include cystic fibrosis, asthma, COPD (chronic obstructive pulmonary disease), bronchiectasis, diabetes, heart failure, and sickle cell anemia.
You're at greater risk for pneumonia if you're in a hospital intensive-care unit, especially if you're on a ventilator (a machine that helps you breathe).
Having a weak or suppressed immune system also raises your risk for pneumonia. A weak immune system may be the result of a disease such as HIV/AIDS. A suppressed immune system may be due to an organ transplant or blood and marrow stem cell transplant, chemotherapy (a treatment for cancer), or long-term steroid use.
Your risk for pneumonia also increases if you have trouble coughing because of a stroke or problems swallowing. You're also at higher risk if you can't move around much or are sedated (given medicine to make you relaxed or sleepy).
Smoking cigarettes, abusing alcohol, or being undernourished also raises your risk for pneumonia. Your risk also goes up if you've recently had a cold or the flu, or if you're exposed to certain chemicals, pollutants, or toxic fumes.
Question: What are the symptoms of Pneumonia ?
Answer: The signs and symptoms of pneumonia vary from mild to severe. Many factors affect how serious pneumonia is, including the type of germ causing the infection and your age and overall health. (For more information, go to "Who Is at Risk for Pneumonia?")
See your doctor promptly if you:
Have a high fever
Have shaking chills
Have a cough with phlegm (a slimy substance), which doesn't improve or worsens
Develop shortness of breath with normal daily activities
Have chest pain when you breathe or cough
Feel suddenly worse after a cold or the flu
People who have pneumonia may have other symptoms, including nausea (feeling sick to the stomach), vomiting, and diarrhea.
Symptoms may vary in certain populations. Newborns and infants may not show any signs of the infection. Or, they may vomit, have a fever and cough, or appear restless, sick, or tired and without energy.
Older adults and people who have serious illnesses or weak immune systems may have fewer and milder symptoms. They may even have a lower than normal temperature. If they already have a lung disease, it may get worse. Older adults who have pneumonia sometimes have sudden changes in mental awareness.
Complications of Pneumonia
Often, people who have pneumonia can be successfully treated and not have complications. But some people, especially those in high-risk groups, may have complications such as:
Bacteremia (bak-ter-E-me-ah). This serious complication occurs if the infection moves into your bloodstream. From there, it can quickly spread to other organs, including your brain.
Lung abscesses. An abscess occurs if pus forms in a cavity in the lung. An abscess usually is treated with antibiotics. Sometimes surgery or drainage with a needle is needed to remove the pus.
Pleural effusion. Pneumonia may cause fluid to build up in the pleural space. This is a very thin space between two layers of tissue that line the lungs and the chest cavity. Pneumonia can cause the fluid to become infecteda condition called empyema (em-pi-E-ma). If this happens, you may need to have the fluid drained through a chest tube or removed with surgery.
Question: What are the treatments for Pneumonia ?
Answer: Treatment for pneumonia depends on the type of pneumonia you have and how severe it is. Most people who have community-acquired pneumoniathe most common type of pneumoniaare treated at home.
The goals of treatment are to cure the infection and prevent complications.
General Treatment
If you have pneumonia, follow your treatment plan, take all medicines as prescribed, and get ongoing medical care. Ask your doctor when you should schedule followup care. Your doctor may want you to have a chest x ray to make sure the pneumonia is gone.
Although you may start feeling better after a few days or weeks, fatigue (tiredness) can persist for up to a month or more. People who are treated in the hospital may need at least 3 weeks before they can go back to their normal routines.
Bacterial Pneumonia
Bacterial pneumonia is treated with medicines called antibiotics. You should take antibiotics as your doctor prescribes. You may start to feel better before you finish the medicine, but you should continue taking it as prescribed. If you stop too soon, the pneumonia may come back.
Most people begin to improve after 1 to 3 days of antibiotic treatment. This means that they should feel better and have fewer symptoms, such as cough and fever.
Viral Pneumonia
Antibiotics don't work when the cause of pneumonia is a virus. If you have viral pneumonia, your doctor may prescribe an antiviral medicine to treat it.
Viral pneumonia usually improves in 1 to 3 weeks.
Treating Severe Symptoms
You may need to be treated in a hospital if:
Your symptoms are severe
You're at risk for complications because of other health problems
If the level of oxygen in your bloodstream is low, you may receive oxygen therapy. If you have bacterial pneumonia, your doctor may give you antibiotics through an intravenous (IV) line inserted into a vein.
