Cardiovascular disease ( CVD ) is a class of diseases that involve the heart or blood vessels. Cardiovascular disease includes coronary artery diseases (CAD) such as angina and myocardial infarction (commonly known as a heart attack). Other CVDs include stroke , and peripheral artery disease. A stroke is a “brain attack”. It can happen to anyone at any time. It occurs when blood flow to an area of brain is cut off. When this happens, brain cells are deprived of oxygen and begin to die. When brain cells die during a stroke, abilities controlled by that area of the brain such as memory and muscle control are lost. Peripheral artery disease (PAD) refers to diseases of the blood vessels located outside the heart and brain. They are most often caused by a buildup of fatty deposits in the arteries. PAD is also known as peripheral arterial disease or peripheral vascular disease (which includes both arteries and veins).
