Acute Coronary Syndrome in a Young Man with no Known Risk Factor

Coronary artery disease occurs at earlier ages due to unhealthy lifestyle associated with increasing industrialization, and extensive cigarette smoking at earlier ages. We report a previously healthy 24-year-old male patient presenting with acute anterior myocardial infarction. The interesting feature of this young patient in whom obstructions of the left anterior descending and circumflex arteries were demostrated angiographicaly was the absence of any known coronary artery disease risk factor including lipoprotein(a), homocystein, apolipoprotein B, C-reactive protein, procoagulant factors, bacteriologic and immunologic analyses. This finding suggests the presence of some unknown important risk factors responsible for the development of coronary artery disease.
