A 19-year-old man with myocardial infarction and sitosterolemia

This is a case report of a 19-year-old man who presented with acute myocardial infarction with obstruction of one coronary artery and rapid progression to three vessels in 8 months. He was proved to have sitosterolemia, a rare hereditary disease with plant sterol storing, resulting in juvenile coronary artery disease. Atherosclerotic complications can be preventable by administration of bile acid-binding resin, after the correct diagnosis is made. We introduce this disease with a review of the literature.
