2. A cardiovascular disease is an illness of the heart and/or blood vessels. It can be caused by a significant build up of plaque in the arteries. Plaque is deposits of cholesterol, calcium, and fat that build up on artery walls.

3. Types of Cardiovascular disease Atherosclerosis: Narrowing of the arteries that results from a buildup of plaque. In cases of severe blockage, a blood clot could close up the artery, leading to a heart attack. Arteriosclerosis: Condition that occurs when plaque hardens on artery walls.

4. Hypertension: Condition of having a blood pressure of 140/90 or higher for an extended period; also called high blood pressure. Stroke: Damage to brain tissue resulting from a clot blocking blood flow to the brain.
