Cholesterol is a waxy, fat-like substance made in the liver and found in certain foods from animals, such as dairy products, eggs, and meat. The body needs some cholesterol in order to function properly. However, too much cholesterol can increase a person's risk of developing heart disease. There are several factors that contribute to high cholesterol -- some are controllable while others are not. Gender: After menopause, a woman's LDL cholesterol level (bad cholesterol) goes up, as does her risk for heart disease.
In the study population (men 40-55 years of age with non-HDL cholesterol greater than 200 mg/dl), the combination of both low levels of HDL cholesterol and triglyceride levels greater than 200 mg/dl were identified as better indicators of increased CHD risk than either total cholesterol or LDL cholesterol alone.
