    • 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.
    • 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.
    • 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.
    • Compare thecrosssection of a clearartery (left) with a llarerarterypartlyobstructedby plaque buildup (right).
    • Preventive Actions You Can Take Now
      Smoking, lack of exercise, and high-fat diets all increase risk. You can lessen your risk of future cardiovascular disease by making certain choices throughout your life. For example, you can limit your intake of cholesterol.
    • Preventive Actions You Can Take Now
      Other preventive measures you can take include limiting your intake of salt and eating lots of fresh fruits, vegetables, and whole-grain foods. Some researchers think that the fiber in these types of food helps to lower cholesterol levels.
    • Preventive Actions You Can Take Now
      The proper diet, combined with regular exercise to maintain cardiovascular fitness, will help keep your circulatory system healthy.
