Question: Who is at risk for Sudden Cardiac Arrest? ?
Answer: The risk of sudden cardiac arrest (SCA) increases:
                
With age
                
If you are a man. Men are more likely than women to have SCA.
                
Some studies show that blacksparticularly those with underlying conditions such as diabetes, high blood pressure, heart failure, and chronic kidney disease or certain cardiac findings on tests such as an electrocardiogramhave a higher risk forSCA.
                
Major Risk Factor
                
The major risk factor for SCA is coronary heart disease. Most people who have SCA have some degree of coronary heart disease; however, many people may not know that they have coronary heart disease until SCA occurs. Usually their coronary heart disease is silentthat is, it has no signs or symptoms. Because of this, doctors and nurses have not detected it.
                
Many people who have SCA also have silent, or undiagnosed, heart attacks before sudden cardiac arrest happens. These people have no clear signs of heart attack, and they dont even realize that theyve had one. Read more about coronary heart disease risk factors.
                
Other Risk Factors
                
Other risk factors for SCA include:
                
A personal history of arrhythmias
                
A personal or family history of SCA or inherited disorders that make you prone toarrhythmias
                
Drug or alcohol abuse
                
Heart attack
                
Heart failure
Question: What are the symptoms of Sudden Cardiac Arrest ?
Answer: Usually, the first sign of sudden cardiac arrest (SCA) is loss of consciousness (fainting). At the same time, no heartbeat (or pulse) can be felt.
                
Some people may have a racing heartbeat or feel dizzy or light-headed just before they faint. Within an hour before SCA, some people have chest pain, shortness of breath, nausea (feeling sick to the stomach), or vomiting.
Question: What is (are) Electrocardiogram ?
Answer: An electrocardiogram (e-lek-tro-KAR-de-o-gram), also called an EKG or ECG, is a simple, painless test that records the heart's electrical activity. To understand this test, it helps to understand how the heart works.
                
With each heartbeat, an electrical signal spreads from the top of the heart to the bottom. As it travels, the signal causes the heart to contract and pump blood. The process repeats with each new heartbeat.
                
The heart's electrical signals set the rhythm of the heartbeat. For more detailed information and animations, go to the Health Topics How the Heart Works article.
                
An EKG shows:
                
How fast your heart is beating
                
Whether the rhythm of your heartbeat is steady or irregular
                
The strength and timing of electrical signals as they pass through each part of your heart
                
Doctors use EKGs to detect and study many heart problems, such as heart attacks, arrhythmias (ah-RITH-me-ahs), and heart failure. The test's results also can suggest other disorders that affect heart function.
Question: What is the outlook for Electrocardiogram ?
Answer: An electrocardiogram (EKG) is painless and harmless. A nurse or technician will attach soft, sticky patches called electrodes to the skin of your chest, arms, and legs. The patches are about the size of a quarter.
                
Often, 12 patches are attached to your body. This helps detect your heart's electrical activity from many areas at the same time. The nurse may have to shave areas of your skin to help the patches stick.
                
After the patches are placed on your skin, you'll lie still on a table while the patches detect your heart's electrical signals. A machine will record these signals on graph paper or display them on a screen.
                
The entire test will take about 10 minutes.
                
EKG
                

                
Special Types of Electrocardiogram
                
The standard EKG described above, called a resting 12-lead EKG, only records seconds of heart activity at a time. It will show a heart problem only if the problem occurs during the test.
                
Many heart problems are present all the time, and a resting 12-lead EKG will detect them. But some heart problems, like those related to an irregular heartbeat, can come and go. They may occur only for a few minutes a day or only while you exercise.
                
Doctors use special EKGs, such as stress tests and Holter and event monitors, to help diagnose these kinds of problems.
                
Stress Test
                
Some heart problems are easier to diagnose when your heart is working hard and beating fast. During stress testing, you exercise to make your heart work hard and beat fast while an EKG is done. If you can't exercise, you'll be given medicine to make your heart work hard and beat fast.
                
For more information, go to the Health Topics Stress Testing article.
                
Holter and Event Monitors
                
Holter and event monitors are small, portable devices. They record your heart's electrical activity while you do your normal daily activities. A Holter monitor records your heart's electrical activity for a full 24- or 48-hour period.
                
An event monitor records your heart's electrical activity only at certain times while you're wearing it. For many event monitors, you push a button to start the monitor when you feel symptoms. Other event monitors start automatically when they sense abnormal heart rhythms.
                
For more information, go to the Health Topics Holter and Event Monitors article.
Question: What is the outlook for Electrocardiogram ?
Answer: After an electrocardiogram (EKG), the nurse or technician will remove the electrodes (soft patches) from your skin. You may develop a rash or redness where the EKG patches were attached. This mild rash often goes away without treatment.
                
You usually can go back to your normal daily routine after an EKG.
Question: Who is at risk for Electrocardiogram? ?
Answer: An electrocardiogram (EKG) has no serious risks. It's a harmless, painless test that detects the heart's electrical activity. EKGs don't give off electrical charges, such as shocks.
                
You may develop a mild rash where the electrodes (soft patches) were attached. This rash often goes away without treatment.
Question: What is (are) Pericarditis ?
Answer: 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.
Question: What causes Pericarditis ?
Answer: 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)
Question: Who is at risk for Pericarditis? ?
Answer: 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.
Question: What are the symptoms of Pericarditis ?
Answer: 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.
Question: What are the treatments for Pericarditis ?
Answer: 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.
Question: How to prevent Pericarditis ?
Answer: 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).
Question: What causes Asbestos-Related Lung Diseases ?
Answer: Significant exposure to asbestos fibers causes asbestos-related lung diseases. "Significant" usually means you were exposed for at least several months to visible dust from the fibers.
                
Asbestos fibers are very small. When you breathe in, they can get stuck deep in your lungs. The fibers remain in your lung tissue for a long time and may cause scarring and inflammation. This can lead to pleural plaque and widespread pleural thickening, pleural effusion, asbestosis, lung cancer, or mesothelioma.
                
Generally, asbestos-related lung diseases develop 10 to 40 or more years after a person has been exposed to asbestos.
                
Being around products that contain asbestos isn't a danger, as long as the asbestos is enclosed. This prevents the fibers from getting into the air.
Question: What are the symptoms of Asbestos-Related Lung Diseases ?
Answer: The signs and symptoms of asbestos-related lung diseases vary. They depend on which disease you have and how much it has damaged your lungs. Signs and symptoms may not appear for 10 to 40 or more years after exposure to asbestos.
                
If you have pleural plaque, you may not have any signs or symptoms. Pleural effusion may cause pain on one side of the chest. Both conditions often are found with a chest x ray. These conditions may occur earlier than other asbestos-related lung diseases.
                
The main symptom of asbestosis is shortness of breath with physical exertion. You also may have a dry cough and feel tired. If your doctor listens to your lungs with a stethoscope, he or she may hear a crackling sound when you breathe in.
                
The symptoms of lung cancer may include a worsening cough or a cough that won't go away, trouble breathing, ongoing chest pain, and coughing up blood. Other symptoms of lung cancer include frequent lung infections, fatigue (tiredness), and weight loss without a known cause.
                
Symptoms of mesothelioma include shortness of breath and chest pain due to pleural effusion.
Question: What are the treatments for Asbestos-Related Lung Diseases ?
Answer: No treatments can reverse the effects of asbestos on your lungs. However, treatments may help relieve symptoms and prevent or delay complications. If you have lung cancer, treatments may help slow the progress of the disease.
                
Treatments for Pleural Plaque, Pleural Effusion, and Asbestosis
                
If you have pleural plaque, pleural effusion, or asbestosis and you smoke, your doctor will advise you to quit smoking. People who have these conditions can lower their risk for lung cancer if they quit smoking.
                
Talk with your doctor about programs and products that can help you quit smoking. 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, go to the Diseases and Conditions Index Smoking and Your Heart article and the National Heart, Lung, and Blood Institutes Your Guide to a Healthy Heart. Although these resources focus on heart health, they include general information about how to quit smoking.
                
If you have trouble breathing or shortness of breath and a very low blood oxygen level, your doctor may recommend oxygen therapy. For this treatment, you're given oxygen through nasal prongs or a mask. Oxygen therapy may be done at home or in a hospital or other health facility.
                
If excess fluid around the lungs (pleural effusion) is making it hard for you to breathe, thoracentesis (THOR-ah-sen-TE-sis) may help. For this procedure, your doctor will insert a thin needle or plastic tube into the space between your lungs and chest wall. He or she will then draw out the excess fluid.
                
Treatments for Lung Cancer and Mesothelioma
                
If you have lung cancer or mesothelioma, your treatment may include surgery, chemotherapy, radiation therapy, and/or targeted therapy. (Targeted therapy uses medicines or other substances to find and attack specific lung cancer cells without harming normal cells.)
                
Your doctor may prescribe medicines to prevent fluid buildup, ease pain, or relieve other complications of your disease.
                
If you have lung cancer or mesothelioma, talk with your doctor about whether you should get flu and pneumonia vaccines. These vaccines can help lower your risk for lung infections.
Question: How to prevent Asbestos-Related Lung Diseases ?
Answer: You can prevent asbestos-related lung diseases by limiting your exposure to asbestos fibers. If your job requires you to work around asbestos, make sure to follow workplace rules for handling it. For example, make sure that air levels are measured, and wear a proper respirator to avoid breathing in asbestos fibers.
                
If you live in a house or work in a building that has pipes or other products containing asbestos, you generally dont need to take special precautions. Being around products that contain asbestos isnt a danger, as long as the asbestos is enclosed. This prevents the fibers from getting into the air.
                
If you smoke, quit. Smoking greatly increases your risk of lung cancer if you have pleural plaque, pleural effusion, or asbestosis. Talk with your doctor about programs and products that can help you quit smoking. 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, go to the Diseases and Conditions Index Smoking and Your Heart article and the National Heart, Lung, and Blood Institutes Your Guide to a Healthy Heart. Although these resources focus on heart health, they include general information about how to quit smoking.
Question: What is (are) Idiopathic Pulmonary Fibrosis ?
Answer: Pulmonary fibrosis (PULL-mun-ary fi-BRO-sis) is a disease in which tissue deep in your lungs becomes thick and stiff, or scarred, over time. The formation of scar tissue is called fibrosis.
                
As the lung tissue thickens, your lungs can't properly move oxygen into your bloodstream. As a result, your brain and other organs don't get the oxygen they need. (For more information, go to the "How the Lungs Work" section of this article.)
                
Sometimes doctors can find out what's causing fibrosis. But in most cases, they can't find a cause. They call these cases idiopathic (id-ee-o-PATH-ick) pulmonary fibrosis (IPF).
                
IPF is a serious disease that usually affects middle-aged and older adults. IPF varies from person to person. In some people, fibrosis happens quickly. In others, the process is much slower. In some people, the disease stays the same for years.
                
IPF has no cure yet. Many people live only about 3 to 5 years after diagnosis. The most common cause of death related to IPF is respiratory failure. Other causes of death include pulmonary hypertension (HI-per-TEN-shun), heart failure, pulmonary embolism (EM-bo-lizm), pneumonia (nu-MO-ne-ah), and lung cancer.
                
Genetics may play a role in causing IPF. If more than one member of your family has IPF, the disease is called familial IPF.
                
Research has helped doctors learn more about IPF. As a result, they can more quickly diagnose the disease now than in the past. Also, researchers are studying several medicines that may slow the progress of IPF. These efforts may improve the lifespan and quality of life for people who have the disease.
