Introduction of Heart Disease

Rheumatic heart disease is a condition where cardiac valve damaged by rheumatic fever.
Congenital heart disease is a type of defect or abnormality in one or more structures of the heart or blood vessels that occur before birth. This defect occurs when the fetus develops in the womb and affects 80-10 of every 1,000 children. Congenital heart defects may produce symptoms at birth, during childhood, and sometimes not until adulthood. Approximately 500,000 people in the U.S. adult congenital heart disease.

Heart attack is the cessation of blood flow, even if only for a moment, that led to the heart, and causes some heart cells to die.
Heart disease is the number one cause of death in adults in the United States. Each year, in the United States:
1.5 million people suffered heart attacks.
478,000 people die from coronary heart disease.
407 000 people experience the transition operation.
300,000 people undergo angioplasty.
Heart disease, stroke and peripheral arterial disease is a deadly disease. Worldwide, the number of people with this disease continues to grow. The three categories of disease is not out of an unhealthy lifestyle that a lot done in line with the changing pattern of life.
These factors trigger a heart attack is smoking, eating foods high cholesterol, lack of movement, supine exercise, stress, and less rest.

Heart attack is a condition when the damage suffered by the heart muscle (myocardium) due to very sudden decrease in blood supply to the heart muscle. Reduced blood supply to the heart suddenly can occur when one of the coronary artery blockage was for some time, either due to spasm - coronary tighten artery - or due to blood clots - thrombus. Sections of heart muscle that is usually supplied by a pulse which block stop functioning properly immediately after splasme subsides by itself, the symptoms disappeared completely and heart muscle function completely normally again. This is often called crescendo angina or coronary insufficiency. Conversely, if the blood supply to the heart stops altogether, the cells in question experienced a permanent change in just a few hours only and referred to the heart muscle is severely degraded or permanently damaged. Muscles of the dead is called infarction.
