Heart disease is a very broad term. Problems can arise in the heart muscle, arteries supplying blood to the heart muscle or valves in the heart that pumps blood into the right direction. Understanding the differences between each disease of the liver can help with the confusing use of the term heart disease.
Coronary artery disease or CAD is the most common form of heart disease and the leading cause of death in both sexes in the United States coronary heart disease affects the arteries supplying the heart muscle with blood. These coronary arteries harden and narrow due buildup of cholesterol, wax, fatty substance called plaque.
This plaque buildup is known as atherosclerosis. Increase in plaque buildup causes narrowing of the coronary arteries. This is the blood flow is restricted to reduce the amount of oxygen to the heart muscle. A reduction in the amount of oxygen supplied to the heart muscle can cause angina (chest pain) and heart attacks. Coronary heart disease over time weaken the heart muscle contributing to heart failure and heart rhythm disturbances (arrhythmias).
Coronary heart disease is another confusing type of heart disease. Coronary heart disease is not the same with coronary heart disease. While coronary heart disease called coronary arteries, coronary heart disease is related to coronary heart disease and resulting complications. These include complications such as chest pain, heart attack, and scarring caused by heart attack. Understand the subtle differences between the two can impress your heart.
Cardiomyopathy is a disease that affects the heart muscle. Cardiomyopathy can be genetic or caused by a viral infection. Cardiomyopathy can be classified as primary or secondary. Primary cardiomyopathy is associated with a specific cause (hypertension, congenital heart defects, heart valve disease). Cardiomyopathy secondary to specific causes (diseases of other organs) is assigned.
There are three main types of cardiomyopathy. Dilated cardiomyopathy is enlargement and stretching of the heart muscle. Hypertrophic cardiomyopathy causes thickening of the heart muscle. Restrictive cardiomyopathy causes the ventricles to rigidly what is the blood flow into the ventricles difficult between heartbeats.
Valvular heart disease is a disease of the heart valves are affected. In the heart valves keep blood flowing in the right direction. Valve damage can by various conditions, insufficiency or regurgitation (leaking valve), prolapse (improper valve closure) or stenosis (narrowing of the valve) cause to be produced. Heart valve defects can be genetic. Heart valve disease can also be caused by certain infections such as rheumatic fever, and certain medications or radiation treatments for cancer are caused.
