Cardiovascular Diseases
Cardiovascular disease is a class of diseases that involve the heart or blood vessels (arteries, capillaries and veins). The causes of cardiovascular disease are diverse but atherosclerosis and/or hypertension are the most common. the biggest cause of deaths

Types.=))
* Coronary heart disease (CHD) is the narrowing or blockage of the coronary arteries, usually caused by atherosclerosis or buildup of cholesterol and fatty deposits on the inner walls of the arteries. Causes - smoking, family history, hypertension, obesity, diabetes, high alcohol consumption, lack of exercise, stress, and hyperlipidemia

* Cardiomyopathy (literally "heart muscle disease") is the measurable deterioration of the function of the myocardium (the heart muscle) for any reason, usually leading to heart failure Cause -most likely UNknown

Types -Dilated cardiomyopathy. This is the most common type of cardiomyopathy. In this disorder, the pumping ability of your heart's main pumping chamber — the left ventricle — becomes less forceful. Hypertrophic cardiomyopathy. This type involves abnormal growth or thickening of your heart muscle, particularly affecting the muscle of your heart's main pumping chamber. Restrictive cardiomyopathy. The heart muscle in people with restrictive cardiomyopathy becomes rigid and less elastic, meaning the heart can't properly expand and fill with blood between heartbeats.

* Hypertensive heart disease refers to heart problems that occur because of high blood pressure. Cause- High blood pressure means the pressure inside the blood vessels (called arteries) is too high. Over time, this causes the heart muscle to thicken.

* Heart failure (HF), often called congestive heart failure (CHF) or congestive cardiac failure (CCF), occurs when the heart is unable to provide sufficient pump action to distribute blood flow to meet the needs of the body. Cause...
