According to the Third Report of the National Cholesterol Education Program, released in 2002, heart disease is caused by the interaction of several factors, one of which is high cholesterol. For example, a man who is 40 years old and has a total cholesterol level of 240 mg/dl has 57 percent chance of developing heart disease in the next 40 years; a woman 40 years old who has a total cholesterol level of 240 mg/dl has a 33 percent chance. A 40-year-old man with a cholesterol level below 200 mg/dl has a 31 percent chance; a 40-year-old woman with a cholesterol level below 200 mg/dl has a 15 percent chance.
