heart Disease details

Coronary Artery Disease:

Also called: CAD, Coronary arteriosclerosis, Coronary atherosclerosis


Coronary artery disease (CAD) is the most common type of heart disease. It is the leading cause of death in the United States in both men and women.

CAD happens when the arteries that supply blood to heart muscle become hardened and narrowed. This is due to the buildup of cholesterol and other material, called plaque, on their inner walls. As the buildup grows, less blood can flow through the arteries. As a result, the heart muscle can't get the blood or oxygen it needs. This can lead to chest pain (angina) or a heart attack. Most heart attacks happen when a blood clot suddenly cuts off the hearts' blood supply, causing permanent heart damage.

Over time, CAD can also weaken the heart muscle and contribute to heart failure and arrhythmias. Heart failure means the heart can't pump blood well to the rest of the body. Arrhythmias are changes in the normal beating rhythm of the heart.

Heart Transplantation:

A heart transplant removes a damaged or diseased heart and replaces it with a healthy one. The healthy heart comes from a donor who has died. It is the last resort for people with heart failure when all other treatments have failed. Heart transplants are now the third most common organ transplant operation in the U.S.


Doctors may recommend a heart transplant for heart failure caused by
• Coronary artery disease
• Cardiomyopathy - disease of the heart muscle
• Heart valve disease
• In babies, multiple congenital heart defects that are too complex to repair

Cardiomyopathy:

Also called: Dilated cardiomyopathy, Hypertrophic cardiomyopathy, Myocardiopathy, Restrictive cardiomyopathy

Cardiomyopathy refers to diseases of the heart muscle. These diseases enlarge your heart muscle or make it thicker and more rigid than normal. In rare cases, scar tissue replaces the muscle tissue.

Some people live long, healthy lives with cardiomyopathy. Some people don't even realize they have it. In others, however, it can make the heart less able to pump blood through the body. This can cause serious complications, including

• Heart failure
• Abnormal heart rhythms
• Fluid buildup in your lungs or legs
• Endocarditis, an inflammation of the heart lining

Heart attacks, high blood pressure or infections can all cause cardiomyopathy. Some types of cardiomyopathy run in families. In many people, however, the cause is unknown. Treatment might involve medicines, surgery, other medical procedures and lifestyle changes.

Arrhythmia:

Also called: Irregular heartbeat

Has your heart ever skipped a beat? Sometimes it really does if you have an arrhythmia. An arrhythmia is any disorder of your heart rate or rhythm. It means that your heart beats too quickly, too slowly or with an irregular pattern. When the heart beats faster than normal, it is called tachycardia. When the heart beats too slowly, it is called bradycardia.

Many factors can affect your heart's rhythm, such as having had a heart attack, blood chemistry imbalances or abnormal hormone levels. Some substances or medicines may also cause arrhythmias.

Symptoms of arrhythmias include

• Fast or slow heart beat
• Skipping beats
• Lightheadedness, dizziness
• Chest pain
• Shortness of breath
• Paleness
• Sweating

Your doctor can run tests to find out if you have an arrhythmia. Treatment to restore a normal heart rhythm may include medicines, an implantable cardioverter-defibrillator (ICD) or a pacemaker.

Heart Diseases--Prevention:

Heart disease is the leading cause of the death in the U.S. Over one quarter of all deaths are from heart disease. It is also a major cause of disability. The risk of heart disease increases as you age. You have a greater risk of heart disease if you are a man over age 45 or a woman over age 55. You also are at greater risk if you have a close family member who had heart disease at an early age.


Fortunately, there are many things you can do reduce your chances of getting heart disease. You should

• Know your blood pressure and keep it under control
• Exercise regularly
• Don't smoke
• Get tested for diabetes and if you have it, keep it under control
• Know your cholesterol and triglyceride levels and keep them under control
• Eat a lot of fruits and vegetables
• Maintain a healthy weight

Triglycerides:

Triglycerides are a type of fat in the bloodstream and fat tissue. Too much of this type of fat can contribute to the hardening and narrowing of your arteries. This puts you at risk of having a heart attack or stroke. Diseases such as diabetes, obesity, kidney failure or alcoholism can cause high triglycerides. Often, high triglycerides occur along with high levels of cholesterol, another type of fat.

Triglycerides are measured along with cholesterol as part of a blood test. Normal triglyceride levels are below 150. Levels above 200 are high. If your triglyceride level is high, you can lower it by

• Getting medical treatment for the problem causing the high triglycerides
• Following a healthy diet low in sugars and carbohydrates
• Exercising regularly
• Taking cholesterol-lowering medicines
