Which factor contributes to plaque formation in coronary arteries?

Question

Quizplus · Accepted Answer

Plaque formation in coronary arteries is primarily caused by the accumulation of low-density lipoproteins (LDL) in damaged or inflamed areas of the artery lining. This leads to the formation of fatty streaks, which can progress to fibrous plaques, and ultimately calcification and hardening of the artery walls. High-density lipoproteins (HDL) are actually considered “good” cholesterol, as they help to remove excess cholesterol from the bloodstream and prevent plaque formation, so inflammation of the lining where HDLs have attached would not contribute to plaque formation. Protein deposits and fat cells may also contribute to plaque formation, but are not the primary cause.
