 Who is at risk for Atrial Fibrillation? ? 
 Atrial fibrillation (AF) affects millions of people, and the number is rising. Men are more likely than women to have the condition. In the United States, AF is more common among Whites than African Americans or Hispanic Americans.
                
The risk of AF increases as you age. This is mostly because your risk for heart disease and other conditions that can cause AF also increases as you age. However, about half of the people who have AF are younger than 75.
                
AF is uncommon in children.
                
Major Risk Factors
                
AF is more common in people who have:
                
High blood pressure
                
Coronary heart disease (CHD)
                
Heart failure
                
Rheumatic (ru-MAT-ik) heart disease
                
Structural heart defects, such as mitral valve prolapse
                
Pericarditis (PER-i-kar-DI-tis; a condition in which the membrane, or sac, around your heart is inflamed)
                
Congenital heart defects
                
Sick sinus syndrome (a condition in which the heart's electrical signals don't fire properly and the heart rate slows down; sometimes the heart will switch back and forth between a slow rate and a fast rate)
                
AF also is more common in people who are having heart attacks or who have just had surgery.
                
Other Risk Factors
                
Other conditions that raise your risk for AF include hyperthyroidism (too much thyroid hormone), obesity, diabetes, and lung disease.
                
Certain factors also can raise your risk for AF. For example, drinking large amounts of alcohol, especially binge drinking, raises your risk. Even modest amounts of alcohol can trigger AF in some people. Caffeine or psychological stress also may trigger AF in some people.
                
Some data suggest that people who have sleep apnea are at greater risk for AF. Sleep apnea is a common disorder that causes one or more pauses in breathing or shallow breaths while you sleep.
                
Metabolic syndrome also raises your risk for AF. Metabolic syndrome is the name for a group of risk factors that raises your risk for CHD and other health problems, such as diabetes and stroke.
                
Research suggests that people who receive high-dose steroid therapy are at increased risk for AF. This therapy is used for asthma and some inflammatory conditions. It may act as a trigger in people who have other AF risk factors.
                
Genetic factors also may play a role in causing AF. However, their role isn't fully known.
This is a medical question of type : symptoms 
 What are the symptoms of Atrial Fibrillation ? 
 Atrial fibrillation (AF) usually causes the heart's lower chambers, the ventricles, to contract faster than normal.
                
When this happens, the ventricles can't completely fill with blood. Thus, they may not be able to pump enough blood to the lungs and body. This can lead to signs and symptoms, such as:
                
Palpitations (feelings that your heart is skipping a beat, fluttering, or beating too hard or fast)
                
Shortness of breath
                
Weakness or problems exercising
                
Chest pain
                
Dizziness or fainting
                
Fatigue (tiredness)
                
Confusion
                
Atrial Fibrillation Complications
                
AF has two major complicationsstroke and heart failure.
                
Stroke
                
During AF, the heart's upper chambers, the atria, don't pump all of their blood to the ventricles. Some blood pools in the atria. When this happens, a blood clot (also called a thrombus) can form.
                
If the clot breaks off and travels to the brain, it can cause a stroke. (A clot that forms in one part of the body and travels in the bloodstream to another part of the body is called an embolus.)
                
Blood-thinning medicines that reduce the risk of stroke are an important part of treatment for people who have AF.
                
Atrial Fibrillation and Stroke
                

                
Heart Failure
                
Heart failure occurs if the heart can't pump enough blood to meet the body's needs. AF can lead to heart failure because the ventricles are beating very fast and can't completely fill with blood. Thus, they may not be able to pump enough blood to the lungs and body.
                
Fatigue and shortness of breath are common symptoms of heart failure. A buildup of fluid in the lungs causes these symptoms. Fluid also can build up in the feet, ankles, and legs, causing weight gain.
                
Lifestyle changes, medicines, and procedures or surgery (rarely, a mechanical heart pump or heart transplant) are the main treatments for heart failure.
This is a medical question of type : prevention 
 How to prevent Atrial Fibrillation ? 
 Following a healthy lifestyle and taking steps to lower your risk for heart disease may help you prevent atrial fibrillation (AF). These steps include:
                
Following a heart healthy diet that's low in saturated fat, trans fat, and cholesterol. A healthy diet includes a variety of whole grains, fruits, and vegetables daily.
                
Not smoking.
                
Being physically active.
                
Maintaining a healthy weight.
                
If you already have heart disease or other AF risk factors, work with your doctor to manage your condition. In addition to adopting the healthy habits above, which can help control heart disease, your doctor may advise you to: 
                
Follow the DASH eating plan to help lower your blood pressure.
                
Keep your cholesterol and triglycerides at healthy levels with dietary changes and medicines (if prescribed).
                
Limit or avoid alcohol.
                
Control your blood sugar level if you have diabetes.
                
Get ongoing medical care and take your medicines as prescribed.

 Who is at risk for Angina? ? 
 Angina is a symptom of an underlying heart problem. Its usually a symptom of coronary heart disease (CHD), but it also can be a symptom of coronary microvascular disease (MVD). So, if youre at risk for CHD or coronary MVD, youre also at risk for angina.
                
The major risk factors for CHD and coronary MVD include:
                
Unhealthy cholesterol levels.
                
High blood pressure.
                
Smoking.
                
Insulin resistance or diabetes.
                
Overweight or obesity.
                
Metabolic syndrome.
                
Lack of physical activity.
                
Unhealthy diet.
                
Older age. (The risk increases for men after 45 years of age and for women after 55 years of age.)
                
Family history of early heart disease.
                
For more detailed information about CHD and coronary MVD risk factors, visit the Diseases and Conditions Index Coronary Heart Disease, Coronary Heart Disease Risk Factors, and Coronary Microvascular Disease articles.
                
People sometimes think that because men have more heart attacks than women, men also suffer from angina more often. In fact, overall, angina occurs equally among men and women.
                
Microvascular angina, however, occurs more often in women. About 70 percent of the cases of microvascular angina occur in women around the time of menopause.
                
Unstable angina occurs more often in older adults. Variant angina is rare; it accounts for only about 2 out of 100 cases of angina. People who have variant angina often are younger than those who have other forms of angina.
This is a medical question of type : symptoms 
 What are the symptoms of Angina ? 
 Pain and discomfort are the main symptoms of angina. Angina often is described as pressure, squeezing, burning, or tightness in the chest. The pain or discomfort usually starts behind the breastbone.
                
Pain from angina also can occur in the arms, shoulders, neck, jaw, throat, or back. The pain may feel like indigestion. Some people say that angina pain is hard to describe or that they can't tell exactly where the pain is coming from.
                
Signs and symptoms such as nausea (feeling sick to your stomach), fatigue (tiredness), shortness of breath, sweating, light-headedness, and weakness also may occur.
                
Women are more likely to feel discomfort in the neck, jaw, throat, abdomen, or back. Shortness of breath is more common in older people and those who have diabetes. Weakness, dizziness, and confusion can mask the signs and symptoms of angina in elderly people.
                
Symptoms also vary based on the type of angina you have.
                
Because angina has so many possible symptoms and causes, all chest pain should be checked by a doctor. Chest pain that lasts longer than a few minutes and isn't relieved by rest or angina medicine may be a sign of a heart attack. Call 911 right away.
                
Stable Angina
                
The pain or discomfort:
                
Occurs when the heart must work harder, usually during physical exertion
                
Doesn't come as a surprise, and episodes of pain tend to be alike
                
Usually lasts a short time (5 minutes or less)
                
Is relieved by rest or medicine
                
May feel like gas or indigestion
                
May feel like chest pain that spreads to the arms, back, or other areas
                
Unstable Angina
                
The pain or discomfort:
                
Often occurs at rest, while sleeping at night, or with little physical exertion
                
Comes as a surprise
                
Is more severe and lasts longer than stable angina (as long as 30 minutes)
                
Usually isnt relieved by rest or medicine
                
May get worse over time
                
May mean that a heart attack will happen soon
                
Variant Angina
                
The pain or discomfort:
                
Usually occurs at rest and during the night or early morning hours
                
Tends to be severe
                
Is relieved by medicine
                
Microvascular Angina
                
The pain or discomfort:
                
May be more severe and last longer than other types of angina pain
                
May occur with shortness of breath, sleep problems, fatigue, and lack of energy
                
Often is first noticed during routine daily activities and times of mental stress
This is a medical question of type : prevention 
 How to prevent Angina ? 
 You can prevent or lower your risk for angina and heart disease by making lifestyle changes and treating related conditions.
                
Making Lifestyle Changes
                
Healthy lifestyle choices can help prevent or delay angina and heart disease. To adopt a healthy lifestyle, you can:
                
Quit smoking and avoid secondhand smoke
                
Avoid angina triggers
                
Follow a healthy diet
                
Be physically active
                
Maintain a healthy weight
                
Learn ways to handle stress and relax
                
Take your medicines as your doctor prescribes
                
For more information about these lifestyle changes, go to How Is Angina Treated? For more information about preventing and controlling heart disease risk factors, visit the Diseases and Conditions Index Coronary Heart Disease, Coronary Heart Disease Risk Factors, and Coronary Microvascular Disease articles.
                
Treating Related Conditions
                
You also can help prevent or delay angina and heart disease by treating related conditions, such as high blood cholesterol, high blood pressure, diabetes, and overweight or obesity.
                
If you have one or more of these conditions, talk with your doctor about how to control them. Follow your treatment plan and take all of your medicines as your doctor prescribes.

 What is (are) Heart Murmur ? 
 A heart murmur is an extra or unusual sound heard during a heartbeat. Murmurs range from very faint to very loud. Sometimes they sound like a whooshing or swishing noise.
                
Normal heartbeats make a "lub-DUPP" or "lub-DUB" sound. This is the sound of the heart valves closing as blood moves through the heart. Doctors can hear these sounds and heart murmurs using a stethoscope.
                
Overview
                
The two types of heart murmurs are innocent (harmless) and abnormal.
                
Innocent heart murmurs aren't caused by heart problems. These murmurs are common in healthy children. Many children will have heart murmurs heard by their doctors at some point in their lives.
                
People who have abnormal heart murmurs may have signs or symptoms of heart problems. Most abnormal murmurs in children are caused by congenital (kon-JEN-ih-tal) heart defects. These defects are problems with the heart's structure that are present at birth.
                
In adults, abnormal heart murmurs most often are caused by acquired heart valve disease. This is heart valve disease that develops as the result of another condition. Infections, diseases, and aging can cause heart valve disease.
                
Outlook
                
A heart murmur isn't a disease, and most murmurs are harmless. Innocent murmurs don't cause symptoms. Having one doesn't require you to limit your physical activity or do anything else special. Although you may have an innocent murmur throughout your life, you won't need treatment for it.
                
The outlook and treatment for abnormal heart murmurs depend on the type and severity of the heart problem causing them.
This is a medical question of type : symptoms 
 What are the symptoms of Heart Murmur ? 
 People who have innocent (harmless) heart murmurs don't have any signs or symptoms other than the murmur itself. This is because innocent heart murmurs aren't caused by heart problems.
                
People who have abnormal heart murmurs may have signs or symptoms of the heart problems causing the murmurs. These signs and symptoms may include:
                
Poor eating and failure to grow normally (in infants)
                
Shortness of breath, which may occur only with physical exertion
                
Excessive sweating with minimal or no exertion
                
Chest pain
                
Dizziness or fainting
                
A bluish color on the skin, especially on the fingertips and lips
                
Chronic cough
                
Swelling or sudden weight gain
                
Enlarged liver
                
Enlarged neck veins
                
Signs and symptoms depend on the problem causing the heart murmur and its severity.
This is a medical question of type : treatment 
 What are the treatments for Heart Murmur ? 
 A heart murmur isn't a disease. It's an extra or unusual sound heard during the heartbeat. Thus, murmurs themselves don't require treatment. However, if an underlying condition is causing a heart murmur, your doctor may recommend treatment for that condition.
                
Innocent (Harmless) Heart Murmurs
                
Healthy children who have innocent (harmless) heart murmurs don't need treatment. Their heart murmurs aren't caused by heart problems or other conditions.
                
Pregnant women who have innocent heart murmurs due to extra blood volume also don't need treatment. Their heart murmurs should go away after pregnancy.
                
Abnormal Heart Murmurs
                
If you or your child has an abnormal heart murmur, your doctor will recommend treatment for the disease or condition causing the murmur.
                
Some medical conditions, such as anemia or hyperthyroidism, can cause heart murmurs that aren't related to heart disease. Treating these conditions should make the heart murmur go away.
                
If a congenital heart defect is causing a heart murmur, treatment will depend on the type and severity of the defect. Treatment may include medicines or surgery. For more information about treatments for congenital heart defects, go to the Health Topics Congenital Heart Defects article.
                
If acquired heart valve disease is causing a heart murmur, treatment usually will depend on the type, amount, and severity of the disease.
                
Currently, no medicines can cure heart valve disease. However, lifestyle changes and medicines can treat symptoms and help delay complications. Eventually, though, you may need surgery to repair or replace a faulty heart valve.

This is a medical question of type : causes 
 What causes Heart Block ? 
 Heart block has many causes. Some people are born with the disorder (congenital), while others develop it during their lifetimes (acquired).
                
Congenital Heart Block
                
One form of congenital heart block occurs in babies whose mothers have autoimmune diseases, such as lupus. People who have these diseases make proteins called antibodies that attack and damage the body's tissues or cells.
                
In pregnant women, antibodies can cross the placenta. (The placenta is the organ that attaches the umbilical cord to the mother's womb.) These proteins can damage the baby's heart and lead to congenital heart block.
                
Congenital heart defects also may cause congenital heart block. These defects are problems with the heart's structure that are present at birth. Often, doctors don't know what causes these defects.
                
Acquired Heart Block
                
Many factors can cause acquired heart block. Examples include:
                
Damage to the heart from a heart attack. This is the most common cause of acquired heart block.
                
Coronary heart disease, also called coronary artery disease.
                
Myocarditis (MI-o-kar-DI-tis), or inflammation of the heart muscle.
                
Heart failure.
                
Rheumatic (roo-MAT-ik) fever.
                
Cardiomyopathy (KAR-de-o-mi-OP-a-the), or heart muscle diseases.
                
Other diseases may increase the risk of heart block. Examples include sarcoidosis (sar-koy-DOE-sis) and the degenerative muscle disorders Lev's disease and Lenegre's disease.
                
Certain types of surgery also may damage the heart's electrical system and lead to heart block.
                
Exposure to toxic substances and taking certain medicinesincluding digitalis, beta blockers, and calcium channel blockersalso may cause heart block. Doctors closely watch people who are taking these medicines for signs of problems.
                
Some types of heart block have been linked to genetic mutations (changes in the genes).
                
An overly active vagus nerve also can cause heart block. You have one vagus nerve on each side of your body. These nerves run from your brain stem all the way to your abdomen. Activity in the vagus nerve slows the heart rate.
                
In some cases, acquired heart block may go away if the factor causing it is treated or resolved. For example, heart block that occurs after a heart attack or surgery may go away during recovery.
                
Also, if a medicine is causing heart block, the disorder may go away if the medicine is stopped or the dosage is lowered. Always talk with your doctor before you change the way you take your medicines.
This is a medical question of type : susceptibility 
 Who is at risk for Heart Block? ? 
 The risk factors for congenital and acquired heart block are different.
                
Congenital Heart Block
                
If a pregnant woman has an autoimmune disease, such as lupus, her fetus is at risk for heart block.
                
Autoimmune diseases can cause the body to make proteins called antibodies that can cross the placenta. (The placenta is the organ that attaches the umbilical cord to the mother's womb.) These antibodies may damage the baby's heart and lead to congenital heart block.
                
Congenital heart defects also can cause heart block. These defects are problems with the heart's structure that are present at birth. Most of the time, doctors don't know what causes congenital heart defects.
                
Heredity may play a role in certain heart defects. For example, a parent who has a congenital heart defect might be more likely than other people to have a child with the condition.
                
Acquired Heart Block
                
Acquired heart block can occur in people of any age. However, most types of the condition are more common in older people. This is because many of the risk factors are more common in older people.
                
People who have a history of heart disease or heart attacks are at increased risk for heart block. Examples of heart disease that can lead to heart block include heart failure, coronary heart disease, and cardiomyopathy (heart muscle diseases).
                
Other diseases also may raise the risk of heart block, such as sarcoidosis and the degenerative muscle disorders Lev's disease and Lenegre's disease.
                
Exposure to toxic substances or taking certain medicines, such as digitalis, also can raise your risk for heart block.
                
Well-trained athletes and young people are at higher risk for first-degree heart block caused by an overly active vagus nerve. You have one vagus nerve on each side of your body. These nerves run from your brain stem all the way to your abdomen. Activity in the vagus nerve slows the heart rate.
This is a medical question of type : symptoms 
 What are the symptoms of Heart Block ? 
 Signs and symptoms depend on the type of heart block you have. First-degree heart block may not cause any symptoms.
                
Signs and symptoms of second- and third-degree heart block include:
                
Fainting
                
Dizziness or light-headedness
                
Fatigue (tiredness)
                
Shortness of breath
                
Chest pain
                
These symptoms may suggest other health problems as well. If these symptoms are new or severe, call 911 or have someone drive you to the hospital emergency room. If you have milder symptoms, talk with your doctor right away to find out whether you need prompt treatment.
