Document Summary
Preventive measures: healthy dietary intake, regular physical activity, and avoiding tobacco. Controlling high blood pressure, and reducing dietary intake of saturated fats and cholesterol: arteriosclerosis: narrowed, hardened arteries. Deposits of fatty substances, cholesterol, cellular waste products, calcium, and fibrin (a clotting material in the blood) in the inner lining of an artery. Plaque may partially or totally block the blood"s flow through an artery. Formation of blood clot (thrombus) on plaque"s surface. When this happens chances of heart attack and stroke increase due to the blocking of the artery. Endothelium (inner lining of arteries) gets affected by: bp, cholesterol & tgs, tobacco. These substances enter the blood to affix to the arterial walls, eventually obstructing blood flow. 3 mayor causes of damage are: a. dramatic fluctuations in blood pressure. B. elevated leves of cholesterol, triglycerides, and glucose in the blood. 75% blocking results in angina pectoris (chest pain).
