What is LDL cholesterol?
the main cholesterol risk factor
LDL carries cholesterol to the body's tissues and is the primary driver of atherosclerosis. Lowering LDL reduces the risk of heart attack and stroke.
LDL particles deposit in artery walls and contribute to plaque formation. The level is shaped by diet, weight, activity, genetics, and certain medications. Familial hypercholesterolaemia produces markedly elevated values.
