How to prevent Cardiogenic Shock ?
The best way to prevent cardiogenic shock is to lower your risk for coronary heart disease (CHD) and heart attack. (For more information, go to the National Heart, Lung, and Blood Institute's "Your Guide to a Healthy Heart.")
                
If you already have CHD, its important to get ongoing treatment from a doctor who has experience treating heart problems.
                
If you have a heart attack, you should get treatment right away to try to prevent cardiogenic shock and other possible complications.
                
Act in time. Know the warning signs of a heart attack so you can act fast to get treatment. Many heart attack victims wait 2 hours or more after their symptoms begin before they seek medical help. Delays in treatment increase the risk of complications and death.
                
If you think you're having a heart attack, call 911 for help. Don't drive yourself or have friends or family drive you to the hospital. Call an ambulance so that medical personnel can begin life-saving treatment on the way to the emergency room. + NHLBI + Cardiogenic Shock
What is (are) Aneurysm ?
An aneurysm (AN-u-rism) is a balloon-like bulge in an artery. Arteries are blood vessels that carry oxygen-rich blood to your body.
                
Arteries have thick walls to withstand normal blood pressure. However, certain medical problems, genetic conditions, and trauma can damage or injure artery walls. The force of blood pushing against the weakened or injured walls can cause an aneurysm.
                
An aneurysm can grow large and rupture (burst) or dissect. A rupture causes dangerous bleeding inside the body. A dissection is a split in one or more layers of the artery wall. The split causes bleeding into and along the layers of the artery wall.
                
Both rupture and dissection often are fatal.
                
Overview
                
Most aneurysms occur in the aorta, the main artery that carries oxygen-rich blood from the heart to the body. The aorta goes through the chest and abdomen.
                
An aneurysm that occurs in the chest portion of the aorta is called a thoracic (tho-RAS-ik) aortic aneurysm. An aneurysm that occurs in the abdominal portion of the aorta is called an abdominal aortic aneurysm.
                
Aneurysms also can occur in other arteries, but these types of aneurysm are less common. This article focuses on aortic aneurysms.
                
About 13,000 Americans die each year from aortic aneurysms. Most of the deaths result from rupture or dissection.
                
Early diagnosis and treatment can help prevent rupture and dissection. However, aneurysms can develop and grow large before causing any symptoms. Thus, people who are at high risk for aneurysms can benefit from early, routine screening.
                
Outlook
                
Doctors often can successfully treat aortic aneurysms with medicines or surgery if theyre found in time. Medicines may be given to lower blood pressure, relax blood vessels, and reduce the risk of rupture.
                
Large aortic aneurysms often can be repaired with surgery. During surgery, the weak or damaged portion of the aorta is replaced or reinforced. + NHLBI + Aneurysm
What causes Aneurysm ?
The force of blood pushing against the walls of an artery combined with damage or injury to the arterys walls can cause an aneurysm.
                
Many conditions and factors can damage and weaken the walls of the aorta and cause aortic aneurysms. Examples include aging, smoking, high blood pressure, and atherosclerosis (ath-er-o-skler-O-sis). Atherosclerosis is the hardening and narrowing of the arteries due to the buildup of a waxy substance called plaque (plak).
                
Rarely, infectionssuch as untreated syphilis (a sexually transmitted infection)can cause aortic aneurysms. Aortic aneurysms also can occur as a result of diseases that inflame the blood vessels, such as vasculitis (vas-kyu-LI-tis).
                
A family history of aneurysms also may play a role in causing aortic aneurysms.
                
In addition to the factors above, certain genetic conditions may cause thoracic aortic aneurysms (TAAs). Examples of these conditions include Marfan syndrome, Loeys-Dietz syndrome, Ehlers-Danlos syndrome (the vascular type), and Turner syndrome.
                
These genetic conditions can weaken the bodys connective tissues and damage the aorta. People who have these conditions tend to develop aneurysms at a younger age than other people. Theyre also at higher risk for rupture and dissection.
                
Trauma, such as a car accident, also can damage the walls of the aorta and lead to TAAs.
                
Researchers continue to look for other causes of aortic aneurysms. For example, theyre looking for genetic mutations (changes in the genes) that may contribute to or cause aneurysms. + NHLBI + Aneurysm
Who is at risk for Aneurysm? ?
Certain factors put you at higher risk for an aortic aneurysm. These factors include:
                
Male gender. Men are more likely than women to have aortic aneurysms.
                
Age. The risk for abdominal aortic aneurysms increases as you get older. These aneurysms are more likely to occur in people who are aged 65 or older.
                
Smoking. Smoking can damage and weaken the walls of the aorta.
                
A family history of aortic aneurysms. People who have family histories of aortic aneurysms are at higher risk for the condition, and they may have aneurysms before the age of 65.
                
A history of aneurysms in the arteries of the legs.
                
Certain diseases and conditions that weaken the walls of the aorta. Examples include high blood pressure and atherosclerosis.
                
Having a bicuspid aortic valve can raise the risk of having a thoracic aortic aneurysm. A bicuspid aortic valve has two leaflets instead of the typical three.
                
Car accidents or trauma also can injure the arteries and increase the risk for aneurysms.
                
If you have any of these risk factors, talk with your doctor about whether you need screening for aneurysms. + NHLBI + Aneurysm
What are the symptoms of Aneurysm ?
The signs and symptoms of an aortic aneurysm depend on the type and location of the aneurysm. Signs and symptoms also depend on whether the aneurysm has ruptured (burst) or is affecting other parts of the body.
                
Aneurysms can develop and grow for years without causing any signs or symptoms. They often don't cause signs or symptoms until they rupture, grow large enough to press on nearby body parts, or block blood flow.
                
Abdominal Aortic Aneurysms
                
Most abdominal aortic aneurysms (AAAs) develop slowly over years. They often don't cause signs or symptoms unless they rupture. If you have an AAA, your doctor may feel a throbbing mass while checking your abdomen.
                
When symptoms are present, they can include:
                
A throbbing feeling in the abdomen
                
Deep pain in your back or the side of your abdomen
                
Steady, gnawing pain in your abdomen that lasts for hours or days
                
If an AAA ruptures, symptoms may include sudden, severe pain in your lower abdomen and back; nausea (feeling sick to your stomach) and vomiting; constipation and problems with urination; clammy, sweaty skin; light-headedness; and a rapid heart rate when standing up.
                
Internal bleeding from a ruptured AAA can send you into shock. Shock is a life-threatening condition in which blood pressure drops so low that the brain, kidneys, and other vital organs can't get enough blood to work well. Shock can be fatal if its not treated right away.
                
Thoracic Aortic Aneurysms
                
A thoracic aortic aneurysm (TAA) may not cause symptoms until it dissects or grows large. If you have symptoms, they may include:
                
Pain in your jaw, neck, back, or chest
                
Coughing and/or hoarseness
                
Shortness of breath and/or trouble breathing or swallowing
                
A dissection is a split in one or more layers of the artery wall. The split causes bleeding into and along the layers of the artery wall.
                
If a TAA ruptures or dissects, you may feel sudden, severe, sharp or stabbing pain starting in your upper back and moving down into your abdomen. You may have pain in your chest and arms, and you can quickly go into shock.
                
If you have any symptoms of TAA or aortic dissection, call 911. If left untreated, these conditions may lead to organ damage or death. + NHLBI + Aneurysm
How to diagnose Aneurysm ?
If you have an aortic aneurysm but no symptoms, your doctor may find it by chance during a routine physical exam. More often, doctors find aneurysms during tests done for other reasons, such as chest or abdominal pain.
                
If you have an abdominal aortic aneurysm (AAA), your doctor may feel a throbbing mass in your abdomen. A rapidly growing aneurysm about to rupture (burst) can be tender and very painful when pressed. If you're overweight or obese, it may be hard for your doctor to feel even a large AAA.
                
If you have an AAA, your doctor may hear rushing blood flow instead of the normal whooshing sound when listening to your abdomen with a stethoscope.
                
Specialists Involved
                
Your primary care doctor may refer you to a cardiothoracic or vascular surgeon for diagnosis and treatment of an aortic aneurysm.
                
A cardiothoracic surgeon does surgery on the heart, lungs, and other organs and structures in the chest, including the aorta. A vascular surgeon does surgery on the aorta and other blood vessels, except those of the heart and brain.
                
Diagnostic Tests and Procedures
                
To diagnose and study an aneurysm, your doctor may recommend one or more of the following tests.
                
Ultrasound and Echocardiography
                
Ultrasound and echocardiography (echo) are simple, painless tests that use sound waves to create pictures of the structures inside your body. These tests can show the size of an aortic aneurysm, if one is found.
                
Computed Tomography Scan
                
A computed tomography scan, or CT scan, is a painless test that uses x rays to take clear, detailed pictures of your organs.
                
During the test, your doctor will inject dye into a vein in your arm. The dye makes your arteries, including your aorta, visible on the CT scan pictures.
                
Your doctor may recommend this test if he or she thinks you have an AAA or a thoracic aortic aneurysm (TAA). A CT scan can show the size and shape of an aneurysm. This test provides more detailed pictures than an ultrasound or echo.
                
Magnetic Resonance Imaging
                
Magnetic resonance imaging (MRI) uses magnets and radio waves to create pictures of the organs and structures in your body. This test works well for detecting aneurysms and pinpointing their size and exact location.
                
Angiography
                
Angiography (an-jee-OG-ra-fee) is a test that uses dye and special x rays to show the insides of your arteries. This test shows the amount of damage and blockage in blood vessels.
                
Aortic angiography shows the inside of your aorta. The test may show the location and size of an aortic aneurysm. + NHLBI + Aneurysm
How to prevent Aneurysm ?
The best way to prevent an aortic aneurysm is to avoid the factors that put you at higher risk for one. You cant control all aortic aneurysm risk factors, but lifestyle changes can help you lower some risks.
                
For example, if you smoke, try to quit. Talk with your doctor about programs and products that can help you quit smoking. Also, try to avoid secondhand smoke. For more information about how to quit smoking, go to the Diseases and Conditions Index (DCI) Smoking and Your Heart article.
                
Another important lifestyle change is following a healthy diet. A healthy diet includes a variety of fruits, vegetables, and whole grains. It also includes lean meats, poultry, fish, beans, and fat-free or low-fat milk or milk products. A healthy diet is low in saturated fat, trans fat, cholesterol, sodium (salt), and added sugar.
                
For more information about following a healthy diet, go to the National Heart, Lung, and Blood Institutes (NHLBIs) Aim for a Healthy Weight Web site, "Your Guide to a Healthy Heart," and "Your Guide to Lowering Your Blood Pressure With DASH." All of these resources include general information about healthy eating.
                
Be as physically active as you can. Talk with your doctor about the amounts and types of physical activity that are safe for you. For more information about physical activity, go to the DCI Physical Activity and Your Heart article and the NHLBIs "Your Guide to Physical Activity and Your Heart."
                
Work with your doctor to control medical conditions such as high blood pressure and high blood cholesterol. Follow your treatment plans and take all of your medicines as your doctor prescribes.
                
Screening for Aneurysms
                
Although you may not be able to prevent an aneurysm, early diagnosis and treatment can help prevent rupture and dissection.
                
Aneurysms can develop and grow large before causing any signs or symptoms. Thus, people who are at high risk for aneurysms may benefit from early, routine screening.
                
Your doctor may recommend routine screening if youre:
                
A man between the ages of 65 and 75 who has ever smoked
                
A man or woman between the ages of 65 and 75 who has a family history of aneurysms
                
If youre at risk, but not in one of these high-risk groups, ask your doctor whether screening will benefit you. + NHLBI + Aneurysm
What is (are) Insomnia ?
Espaol
                
Insomnia (in-SOM-ne-ah) is a common sleep disorder. People who have insomnia have trouble falling asleep, staying asleep, or both. As a result, they may get too little sleep or have poor-quality sleep. They may not feel refreshed when they wake up.
                
Overview
                
Insomnia can be acute (short-term) or chronic (ongoing). Acute insomnia is common and often is brought on by situations such as stress at work, family pressures, or a traumatic event. Acute insomnia lasts for days or weeks.
                
Chronic insomnia lasts for a month or longer. Most cases of chronic insomnia are secondary, which means they are the symptom or side effect of some other problem. Certain medical conditions, medicines, sleep disorders, and substances can cause secondary insomnia.
                
In contrast, primary insomnia isn't due to medical problems, medicines, or other substances. It is its own distinct disorder, and its cause isnt well understood. Many life changes can trigger primary insomnia, including long-lasting stress and emotional upset.
                
Insomnia can cause daytime sleepiness and a lack of energy. It also can make you feel anxious, depressed, or irritable. You may have trouble focusing on tasks, paying attention, learning, and remembering. These problems can prevent you from doing your best at work or school.
                
Insomnia also can cause other serious problems. For example, you may feel drowsy while driving, which could lead to an accident.
                
Outlook
                
Treating the underlying cause of secondary insomnia may resolve or improve the sleep problem, especially if you can correct the problem soon after it starts. For example, if caffeine is causing your insomnia, stopping or limiting your intake of the substance might make the insomnia go away.
                
Lifestyle changes, including better sleep habits, often help relieve acute insomnia. For chronic insomnia, your doctor may recommend medicines or cognitive-behavioral therapy. + NHLBI + Insomnia
What causes Insomnia ?
Secondary Insomnia
                
Secondary insomnia is the symptom or side effect of another problem. This type of insomnia often is a symptom of an emotional, neurological, or other medical or sleep disorder.
                
Emotional disorders that can cause insomnia include depression, anxiety, and posttraumatic stress disorder. Alzheimer's disease and Parkinson's disease are examples of neurological disorders that can cause insomnia.
                
Many other disorders or factors also can cause insomnia, such as:
                
Conditions that cause chronic (ongoing) pain, such as arthritis and headache disorders
                
Conditions that make it hard to breathe, such as asthma and heart failure
                
An overactive thyroid
                
Gastrointestinal disorders, such as heartburn
                
Stroke
                
Sleep disorders, such as restless legs syndrome and sleep-related breathing problems
                
Menopause and hot flashes
                
Secondary insomnia also can be a side effect of some medicines. For example, certain asthma medicines, such as theophylline, and some allergy and cold medicines can cause insomnia. Beta blockers also can cause the condition. These medicines are used to treat heart conditions.
                
Commonly used substances also can cause insomnia. Examples include caffeine and other stimulants, tobacco and other nicotine products, and alcohol and other sedatives.
                
Primary Insomnia
                
Primary insomnia isn't a symptom or side effect of another medical condition. It is its own distinct disorder, and its cause isnt well understood. Primary insomnia usually lasts for at least 1 month.
                
Many life changes can trigger primary insomnia. It may be due to major or long-lasting stress or emotional upset. Travel or other factors, such as work schedules that disrupt your sleep routine, also may trigger primary insomnia.
                
Even if these issues are resolved, the insomnia may not go away. Trouble sleeping can persist because of habits formed to deal with the lack of sleep. These habits might include taking naps, worrying about sleep, and going to bed early.
                
Researchers continue to try to find out whether some people are born with an increased risk for primary insomnia. + NHLBI + Insomnia
Who is at risk for Insomnia? ?
Insomnia is a common disorder. It affects women more often than men. The disorder can occur at any age. However, older adults are more likely to have insomnia than younger people.
                
People who might be at increased risk for insomnia include those who:
                
Have a lot of stress.
                
Are depressed or have other emotional distress, such as divorce or death of a spouse.
                
Have lower incomes.
                
Work at night or have frequent major shifts in their work hours.
                
Travel long distances with time changes.
                
Have certain medical conditions or sleep disorders that can disrupt sleep. For more information, go to "What Causes Insomnia?"
                
Have an inactive lifestyle.
                
Young and middle-aged African Americans also might be at increased risk for insomnia. Research shows that, compared with Caucasian Americans, it takes African Americans longer to fall asleep. They also have lighter sleep, don't sleep as well, and take more naps. Sleep-related breathing problems also are more common among African Americans. + NHLBI + Insomnia
What are the symptoms of Insomnia ?
The main symptom of insomnia is trouble falling or staying asleep, which leads to lack of sleep. If you have insomnia, you may:
                
Lie awake for a long time before you fall asleep
                
Sleep for only short periods
                
Be awake for much of the night
                
Feel as if you haven't slept at all
                
Wake up too early
                
The lack of sleep can cause other symptoms. You may wake up feeling tired or not well-rested, and you may feel tired during the day. You also may have trouble focusing on tasks. Insomnia can cause you to feel anxious, depressed, or irritable.
                
Insomnia also can affect your daily activities and cause serious problems. For example, you may feel drowsy while driving. Driver sleepiness (not related to alcohol) is responsible for almost 20 percent of all serious car crash injuries. Research also shows that insomnia raises older womens risk of falling.
                
If insomnia is affecting your daily activities, talk with your doctor. Treatment may help you avoid symptoms and problems related to the disorder. Also, poor sleep may be a sign of other health problems. Finding and treating those problems could improve your overall health and sleep. + NHLBI + Insomnia
What is (are) Von Willebrand Disease ?
Von Willebrand disease (VWD) is a bleeding disorder. It affects your blood's ability to clot. If your blood doesn't clot, you can have heavy, hard-to-stop bleeding after an injury. The bleeding can damage your internal organs. Rarely, the bleeding may even cause death.
                
In VWD, you either have low levels of a certain protein in your blood or the protein doesn't work well. The protein is called von Willebrand factor, and it helps your blood clot.
                
Normally, when one of your blood vessels is injured, you start to bleed. Small blood cell fragments called platelets (PLATE-lets) clump together to plug the hole in the blood vessel and stop the bleeding. Von Willebrand factor acts like glue to help the platelets stick together and form a blood clot.
                
Von Willebrand factor also carries clotting factor VIII (8), another important protein that helps your blood clot. Factor VIII is the protein that's missing or doesn't work well in people who have hemophilia, another bleeding disorder.
                
VWD is more common and usually milder than hemophilia. In fact, VWD is the most common inherited bleeding disorder. It occurs in about 1 out of every 100 to 1,000 people. VWD affects both males and females, while hemophilia mainly affects males.
                
Types of von Willebrand Disease
                
The three major types of VWD are called type 1, type 2, and type 3.
                
Type 1
                
People who have type 1 VWD have low levels of von Willebrand factor and may have low levels of factor VIII. Type 1 is the mildest and most common form of VWD. About 3 out of 4 people who have VWD have type 1.
                
Type 2
                
In type 2 VWD, the von Willebrand factor doesn't work well. Type 2 is divided into subtypes: 2A, 2B, 2M, and 2N. Different gene mutations (changes) cause each type, and each is treated differently. Thus, it's important to know the exact type of VWD that you have.
                
Type 3
                
People who have type 3 VWD usually have no von Willebrand factor and low levels of factor VIII. Type 3 is the most serious form of VWD, but it's very rare.
                
Overview
                
Most people who have VWD have type 1, a mild form. This type usually doesn't cause life-threatening bleeding. You may need treatment only if you have surgery, tooth extraction, or trauma. Treatment includes medicines and medical therapies.
                
Some people who have severe forms of VWD need emergency treatment to stop bleeding before it becomes life threatening.
                
Early diagnosis is important. With the proper treatment plan, even people who have type 3 VWD can live normal, active lives. + NHLBI + Von Willebrand Disease
