How to diagnose Heart Attack ? 
 Your doctor will diagnose a heart attack based on your signs and symptoms, your medical and family histories, and test results.
                
Diagnostic Tests
                
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 each part of the heart.
                
An EKG can show signs of heart damage due to coronary heart disease (CHD) and signs of a previous or current heart attack.
                
Blood Tests
                
During a heart attack, heart muscle cells die and release proteins into the bloodstream. Blood tests can measure the amount of these proteins in the bloodstream. Higher than normal levels of these proteins suggest a heart attack.
                
Commonly used blood tests include troponin tests, CK or CKMB tests, and serum myoglobin tests. Blood tests often are repeated to check for changes over time.
                
Coronary Angiography
                
Coronary angiography (an-jee-OG-ra-fee) is a test that uses dye and special x rays to show the insides of your coronary arteries. This test often is done during a heart attack to help find blockages in the coronary arteries.
                
To get the dye into your coronary arteries, your doctor will use a procedure called cardiac catheterization (KATH-e-ter-ih-ZA-shun).
                
A thin, flexible tube called a catheter is put into a blood vessel in your arm, groin (upper thigh), or neck. The tube is threaded into your coronary arteries, and the dye is released into your bloodstream.
                
Special x rays are taken while the dye is flowing through the coronary arteries. The dye lets your doctor study the flow of blood through the heart and blood vessels.
                
If your doctor finds a blockage, he or she may recommend a procedure calledpercutaneous (per-ku-TA-ne-us) coronary intervention (PCI), sometimes referred to ascoronary angioplasty(AN-jee-oh-plas-tee). This procedure can help restore blood flow through a blocked artery. Sometimes a small mesh tube called a stent is placed in the artery to help prevent blockages after the procedure.
How to prevent Heart Attack ? 
 Lowering your risk factors for coronary heart disease can help you prevent a heart attack. Even if you already have coronary heart disease, you still can take steps to lower your risk for a heart attack. These steps involve following a heart-healthy lifestyle and getting ongoingmedical care.
                
Heart-Healthy Lifestyle
                
A heart-healthy lifestyle can help prevent a heart attack and includes heart-healthy eating, being physically active, quitting smoking, managing stress, and managing your weight.
                
Ongoing Care
                
Treat Related Conditions
                
Treating conditions that make a heart attack more likely also can help lower your risk for a heart attack. These conditions may include:
                
Diabetes (high blood sugar). If you have diabetes, try to control your blood sugar level through diet and physical activity (as your doctor recommends). If needed, take medicine as prescribed.
                
High blood cholesterol. Your doctor may prescribe a statin medicine to lower your cholesterol if diet and exercise arent enough.
                
High blood pressure. Your doctor may prescribe medicine to keep your blood pressure under control.
                
Have an Emergency Action Plan
                
Make sure that you have an emergency action plan in case you or someone in your family has a heart attack. This is very important if youre at high risk for, or have already had, a heart attack.
                
Write down a list of medicines you are taking, medicines you are allergic to, your health care providers phone numbers (both during and after office hours), and contact information for a friend or relative. Keep the list in a handy place (for example, fill out this wallet card) to share in a medical emergency.
                
Talk with your doctor about the signs and symptoms of a heart attack, when you should call 911, and steps you can take while waiting for medical help to arrive.
What is (are) Pericarditis ? 
 Pericarditis (PER-i-kar-DI-tis) is a condition in which the membrane, or sac, around your heart is inflamed. This sac is called the pericardium (per-i-KAR-de-um).
                
The pericardium holds the heart in place and helps it work properly. The sac is made of two thin layers of tissue that enclose your heart. Between the two layers is a small amount of fluid. This fluid keeps the layers from rubbing against each other and causing friction.
                
Pericardium
                

                
In pericarditis, the layers of tissue become inflamed and can rub against the heart. This causes chest pain, a common symptom of pericarditis.
                
The chest pain from pericarditis may feel like pain from a heart attack. More often, the pain may be sharp and get worse when you inhale, and improve when you are sitting up and leaning forward. If you have chest pain, you should call 911 right away, as you may be having a heart attack.
                
Overview
                
In many cases, the cause of pericarditis is unknown. Viral infections are likely a common cause of pericarditis, although the virus may never be found. Bacterial, fungal, and other infections also can cause pericarditis.
                
Other possible causes include heart attack or heart surgery, other medical conditions, injuries, and certain medicines.
                
Pericarditis can be acute or chronic. "Acute" means that it occurs suddenly and usually doesn't last long. "Chronic" means that it develops over time and may take longer to treat.
                
Both acute and chronic pericarditis can disrupt your heart's normal rhythm or function and possibly (although rarely) lead to death. However, most cases of pericarditis are mild; they clear up on their own or with rest and simple treatment.
                
Other times, more intense treatments are needed to prevent complications. Treatments may include medicines and, less often, procedures or surgery.
                
Outlook
                
It may take from a few days to weeks or even months to recover from pericarditis. With proper and prompt treatment, such as rest and ongoing care, most people fully recover from pericarditis. Proper treatment also can help reduce the chance of getting the condition again.
What causes Pericarditis ? 
 In many cases, the cause of pericarditis (both acute and chronic) is unknown.
                
Viral infections are likely a common cause of pericarditis, although the virus may never be found. Pericarditis often occurs after a respiratory infection. Bacterial, fungal, and other infections also can cause pericarditis.
                
Most cases of chronic, or recurring, pericarditis are thought to be the result of autoimmune disorders. Examples of such disorders include lupus, scleroderma, and rheumatoid arthritis.
                
With autoimmune disorders, the body's immune system makes antibodies (proteins) that mistakenly attack the body's tissues or cells.
                
Other possible causes of pericarditis are:
                
Heart attack and heart surgery
                
Kidney failure, HIV/AIDS, cancer, tuberculosis, and other health problems
                
Injuries from accidents or radiation therapy
                
Certain medicines, like phenytoin (an antiseizure medicine), warfarin and heparin (blood-thinning medicines), and procainamide (a medicine to treat irregular heartbeats)
Who is at risk for Pericarditis? ? 
 Pericarditis occurs in people of all ages. However, men aged 20 to 50 are more likely to develop it than others.
                
People who are treated for acute pericarditis may get it again. This may happen in 15 to 30 percent of people who have the condition. A small number of these people go on to develop chronic pericarditis.
What are the symptoms of Pericarditis ? 
 The most common sign of acute pericarditis is sharp, stabbing chest pain. The pain usually comes on quickly. It often is felt in the middle or left side of the chest or over the front of the chest. You also may feel pain in one or both shoulders, the neck, back, and abdomen.
                
The pain tends to ease when you sit up and lean forward. Lying down and deep breathing worsens it. For some people, the pain feels like a dull ache or pressure in the chest.
                
The chest pain also may feel like pain from a heart attack. If you have chest pain, you should call 911 right away, as you may be having a heart attack.
                
Some people with acute pericarditis develop a fever. Other symptoms are weakness, palpitations, trouble breathing, and coughing. (Palpitations are feelings that your heart is skipping a beat, fluttering, or beating too hard or too fast.)
                
The most common symptom of chronic pericarditis is chest pain. Chronic pericarditis also often causes tiredness, coughing, and shortness of breath. Severe cases of chronic pericarditis can lead to swelling in the stomach and legs and hypotension (low blood pressure).
                
Complications of Pericarditis
                
Two serious complications of pericarditis are cardiac tamponade (tam-po-NAD) and chronic constrictive pericarditis.
                
Cardiac tamponade occurs if too much fluid collects in the pericardium (the sac around the heart). The extra fluid puts pressure on the heart. This prevents the heart from properly filling with blood. As a result, less blood leaves the heart, which causes a sharp drop in blood pressure. If left untreated, cardiac tamponade can be fatal.
                
Chronic constrictive pericarditis is a rare disease that develops over time. It leads to scar-like tissue forming throughout the pericardium. The sac becomes stiff and can't move properly. In time, the scarred tissue compresses the heart and prevents it from working well.
What are the treatments for Pericarditis ? 
 Most cases of pericarditis are mild; they clear up on their own or with rest and simple treatment. Other times, more intense treatment is needed to prevent complications. Treatment may include medicines and, less often, procedures or surgery.
                
The goals of treatment include:
                
Reducing pain and inflammation
                
Treating the underlying cause, if it's known
                
Checking for complications
                
Specific Types of Treatment
                
As a first step in your treatment, your doctor may advise you to rest until you feel better and have no fever. He or she may tell you to take over-the-counter, anti-inflammatory medicines to reduce pain and inflammation. Examples of these medicines include aspirin and ibuprofen.
                
You may need stronger medicine if your pain is severe. If your pain continues to be severe, your doctor may prescribe a medicine called colchicine and, possibly, prednisone (a steroid medicine).
                
If an infection is causing your pericarditis, your doctor will prescribe an antibiotic or other medicine to treat the infection.
                
You may need to stay in the hospital during treatment for pericarditis so your doctor can check you for complications.
                
The symptoms of acute pericarditis can last from a few days to 3 weeks. Chronic pericarditis may last several months.
                
Other Types of Treatment
                
You may need treatment for complications of pericarditis. Two serious complications are cardiac tamponade and chronic constrictive pericarditis.
                
Cardiac tamponade is treated with a procedure called pericardiocentesis (per-ih-KAR-de-o-sen-TE-sis). A needle or tube (called a catheter) is inserted into the chest wall to remove excess fluid in the pericardium. This procedure relieves pressure on the heart.
                
The only cure for chronic constrictive pericarditis is surgery to remove the pericardium. This is known as a pericardiectomy (PER-i-kar-de-EK-to-me).
                
The treatments for these complications require hospital stays.
How to prevent Pericarditis ? 
 You usually can't prevent acute pericarditis. You can take steps to reduce your chance of having another acute episode, having complications, or getting chronic pericarditis.
                
These steps include getting prompt treatment, following your treatment plan, and having ongoing medical care (as your doctor advises).
What causes Obesity Hypoventilation Syndrome ? 
 Obesity hypoventilation syndrome (OHS) is a breathing disorder that affects some obese people. Why these people develop OHS isn't fully known. Researchers think that several factors may work together to cause OHS. These factors include:
                
A respiratory (RES-pih-rah-tor-e) system that has to work harder than normal and perhaps differently because of excess body weight. (The respiratory system is a group of organs and tissues, including the lungs, that helps you breathe.)
                
A slow response by the body to fix the problem of too much carbon dioxide and too little oxygen in the blood.
                
The presence of sleep apnea, usually obstructive sleep apnea.
Who is at risk for Obesity Hypoventilation Syndrome? ? 
 People who are obese are at risk for obesity hypoventilation syndrome (OHS). "Obesity" refers to having too much body fat. People who are obese have body weight that's greater than what is considered healthy for a certain height.
                
The most useful measure of obesity is body mass index (BMI). BMI is calculated from your height and weight. In adults, a BMI of 30 or more is considered obese.
                
You can use the National Heart, Lung, and Blood Institute's (NHLBI's) online BMI calculator to figure out your BMI, or your doctor can help you.
                
If you are obese, you're at greater risk for OHS if your BMI is 40 or higher. You're also at greater risk if most of your excess weight is around your waist, rather than at your hips. This is referred to as "abdominal obesity."
                
OHS tends to occur more often in men than women. At the time of diagnosis, most people are 40 to 60 years old.
What are the symptoms of Obesity Hypoventilation Syndrome ? 
 Many of the signs and symptoms of obesity hypoventilation syndrome (OHS) are the same as those of obstructive sleep apnea. This is because many people who have OHS also have obstructive sleep apnea.
                
One of the most common signs of obstructive sleep apnea is loud and chronic (ongoing) snoring. Pauses may occur in the snoring. Choking or gasping may follow the pauses.
                
Other symptoms include:
                
Daytime sleepiness
                
Morning headaches
                
Memory, learning, or concentration problems
                
Feeling irritable or depressed, or having mood swings or personality changes
                
You also may have rapid, shallow breathing. During a physical exam, your doctor might hear abnormal heart sounds while listening to your heart with a stethoscope. He or she also might notice that the opening to your throat is small and your neck is larger than normal.
                
Complications of Obesity Hypoventilation Syndrome
                
When left untreated, OHS can cause serious problems, such as:
                
Leg edema, which is swelling in the legs caused by fluid in the body's tissues.
                
Pulmonary hypertension, which is increased pressure in the pulmonary arteries. These arteries carry blood from your heart to your lungs to pick up oxygen.
                
Cor pulmonale, which is failure of the right side of the heart.
                
Secondary erythrocytosis, which is a condition in which the body makes too many red blood cells.
How to prevent Obesity Hypoventilation Syndrome ? 
 You can prevent obesity hypoventilation syndrome (OHS) by maintaining a healthy weight. However, not everyone who is obese develops OHS. Researchers don't fully know why only some people who are obese develop the condition.
                
Adopting healthy habits can help you maintain a healthy weight. Many lifestyle habits begin during childhood. So, it's important to make following a healthy lifestyle a family goal.
                
A healthy diet is an important part of a healthy lifestyle. A healthy diet includes a variety of vegetables and fruits. It also includes whole grains, fat-free or low-fat dairy products, and protein foods, such as lean meats, eggs, poultry without skin, seafood, nuts, seeds, beans, and peas.
                
A healthy diet is low in sodium (salt), added sugars, solid fats, and refined grains. Solid fats are saturated fat and trans fatty acids. Refined grains come from processing whole grains, which results in a loss of nutrients (such as dietary fiber). Examples of refined grains include white rice and white bread.
                
For more information about following a healthy diet, go to the National Heart, Lung, and Blood Institute's "Your Guide to Lowering Your Blood Pressure With DASH" and the U.S. Department of Agriculture's ChooseMyPlate.gov Web site. Both resources provide general information about healthy eating.
                
To adopt other healthy lifestyle habits, follow these tips:
                
Focus on portion size. Watch the portion sizes in fast food and other restaurants. The portions served often are enough for two or three people. Children's portion sizes should be smaller than those for adults. Cutting back on portion sizes will help you manage your calorie intake.
                
Be physically active. Make personal and family time as active as possible. Find activities that everyone will enjoy. For example, go for a brisk walk, bike or rollerblade, or train together for a walk or run.
                
Reduce screen time. Limit the use of TVs, computers, DVDs, and videogames; they cut back on the time for physical activity. Health experts recommend2 hours or less a day of screen time that's not work- or homework-related.
                
Keep track of your weight and body mass index (BMI). BMI is calculated from your height and weight. In adults, a BMI of 30 or more is considered obese. You can use the NHLBI's online BMI calculator to figure out your BMI, or your doctor can help you.
                
For more information, go to the prevention section of the Health Topics Overweight and Obesity article.
                
Even if you have OHS, you might be able to prevent the condition from worsening. For example, avoid alcohol, sedatives, and narcotics. These substances can interfere with how well your body is able to maintain normal carbon dioxide and oxygen levels.
What is (are) Hemolytic Anemia ? 
 Hemolytic anemia (HEE-moh-lit-ick uh-NEE-me-uh) is a condition in which red blood cells are destroyed and removed from the bloodstream before their normal lifespan is over.
                
Red blood cells are disc-shaped and look like doughnuts without holes in the center. These cells carry oxygen to your body. They also remove carbon dioxide (a waste product) from your body.
                
Red blood cells are made in the bone marrowa sponge-like tissue inside the bones. They live for about 120 days in the bloodstream and then die.
                
White blood cells and platelets (PLATE-lets) also are made in the bone marrow. White blood cells help fight infections. Platelets stick together to seal small cuts or breaks on blood vessel walls and stop bleeding.
                
When blood cells die, the body's bone marrow makes more blood cells to replace them. However, in hemolytic anemia, the bone marrow can't make red blood cells fast enough to meet the body's needs.
                
Hemolytic anemia can lead to many health problems, such as fatigue (tiredness), pain, irregular heartbeats called arrhythmias (ah-RITH-me-ahs), an enlarged heart, and heart failure.
                
Overview
                
Hemolytic anemia is a type of anemia. The term "anemia" usually refers to a condition in which the blood has a lower than normal number of red blood cells.
                
Anemia also can occur if your red blood cells don't contain enough hemoglobin (HEE-muh-glow-bin). Hemoglobin is an iron-rich protein that carries oxygen from the lungs to the rest of the body.
                
Anemia has three main causes: blood loss, lack of red blood cell production, or high rates of red blood cell destruction.
                
Hemolytic anemia is caused by high rates of red blood cell destruction. Many diseases, conditions, and factors can cause the body to destroy its red blood cells.
                
These causes can be inherited or acquired. "Inherited" means your parents passed the gene(s) for the condition on to you. "Acquired" means you aren't born with the condition, but you develop it. Sometimes the cause of hemolytic anemia isn't known.
                
Outlook
                
There are many types of hemolytic anemia. Treatment and outlook depend on what type you have and how severe it is. The condition can develop suddenly or slowly. Symptoms can range from mild to severe.
                
Hemolytic anemia often can be successfully treated or controlled. Mild hemolytic anemia may need no treatment at all. Severe hemolytic anemia requires prompt and proper treatment, or it may be fatal.
                
Inherited forms of hemolytic anemia are lifelong conditions that may require ongoing treatment. Acquired forms of hemolytic anemia may go away if the cause of the condition is found and corrected.
What causes Hemolytic Anemia ? 
 The immediate cause of hemolytic anemia is the early destruction of red blood cells. This means that red blood cells are destroyed and removed from the bloodstream before their normal lifespan is over.
                
Many diseases, conditions, and factors can cause the body to destroy its red blood cells. These causes can be inherited or acquired. "Inherited" means your parents passed the gene for the condition on to you. "Acquired" means you aren't born with the condition, but you develop it.
                
Sometimes, the cause of hemolytic anemia isn't known.
                
For more information about the specific causes of hemolytic anemia, go to "Types of Hemolytic Anemia."
                
Inherited Hemolytic Anemias
                
In inherited hemolytic anemias, the genes that control how red blood cells are made are faulty. You can get a faulty red blood cell gene from one or both of your parents.
                
Different types of faulty genes cause different types of inherited hemolytic anemia. However, in each type, the body makes abnormal red blood cells. The problem with the red blood cells may involve the hemoglobin, cell membrane, or enzymes that maintain healthy red blood cells.
                
The abnormal cells may be fragile and break down while moving through the bloodstream. If this happens, an organ called the spleen may remove the cell debris from the bloodstream.
                
Acquired Hemolytic Anemias
                
In acquired hemolytic anemias, the body makes normal red blood cells. However, a disease, condition, or other factor destroys the cells. Examples of conditions that can destroy the red blood cells include:
                
Immune disorders
                
Infections
                
Reactions to medicines or blood transfusions
                
Hypersplenism (HI-per-SPLEEN-izm; an enlarged spleen)
Who is at risk for Hemolytic Anemia? ? 
 Hemolytic anemia can affect people of all ages and races and both sexes. Some types of hemolytic anemia are more likely to occur in certain populations than others.
                
For example, glucose-6-phosphate dehydrogenase (G6PD) deficiency mostly affects males of African or Mediterranean descent. In the United States, the condition is more common among African Americans than Caucasians.
                
In the United States, sickle cell anemia mainly affects African Americans.
