Quizplus · Accepted Answer

Arteriosclerosis, the hardening and narrowing of the arteries, is the underlying cause of coronary heart disease. It occurs when cholesterol and other fatty substances build up in the arteries, forming plaques that reduce blood flow to the heart. Myocardial infarction (heart attack) is a potential complication of coronary heart disease, but not its underlying cause. High levels of estrogen can actually have a protective effect on the heart, while high levels of progesterone are not a known risk factor for coronary heart disease.
