Abnormal cholesterol is a major risk factor for coronary artery disease. Bad cholesterol (LDL) can increase risk, while good cholesterol (HDL) can improve risk. Triglycerides and other measured cholesterol values can also play an important role in predicting risk of a heart attack.
LDL Cholesterol Oxidation
LDL-cholesterol is known as "bad" cholesterol. In reality, a process known as oxidation is what makes the cholesterol stick to the insides of your arteries and cause blockages (plaques)
Raising HDL
Low HDL increases the risk of coronary artery disease and heart attacks. Both lifestyle modification and medical management are effective in increasing HDL.
Cholesterol - What's So Bad About It?
It's now well known that abnormal cholesterol levels contribute to blockage of coronary arteries, and thus to heart attacks. However, not all cholesterol is bad. The effects of cholesterol on the different parts of the body are explored in this article.
HDL: The Good Cholesterol
Groups of people with very high good cholesterol like Eskimos, have a very low rate of heart disease. Good cholesterol can prevent coronary artery disease and heart attacks. It may also be able to reverse coronary artery disease that is already there.
