What causes coronary heart disease?
Coronary heart disease is caused by narrowing of the inside walls of the coronary arteries. This narrowing decreases and sometimes completely cuts off the supply of oxygen and nutrients to the heart. Narrowing of the inside walls usually happen when a person has high levels of cholesterol, a fat-like substance, in the blood. Cholesterol and fat, flowing in the blood, builds up on the walls of the arteries. The buildup thickens the arteries and can slow or block the circulation of blood. When the level of cholesterol in the blood is high, there is a greater possibility that it will be deposited onto the artery walls. High blood cholesterol, high blood pressure, and smoking double your chance of developing heart disease. Obesity increases the possibility of developing high blood cholesterol and high blood pressure, and physical inactivity increases the risk of heart attack.
