Why is LDL (low density lipoprotein) cholesterol bad?

ANSWER

LDL cholesterol collects in the walls of arteries, leading to "hardening of the arteries" or atherosclerosis. People with atherosclerosis are in turn vulnerable to heart failure, heart attack, stroke, and other problems caused by clogged blood vessels. Even so, some people who have high LDL cholesterol never get heart disease, and many heart attack patients do not have high cholesterol levels.
