Chronic Total Occlusions of the Right Coronary and Left Anterior Descending Coronary Arteries in a Young Adult Patient with Antiphospholipid Syndrome

A 36-year-old male appeared to have an old myocardial infarction on electrocardiogram, and coronary angiography (CAG) was performed. The CAG showed total occlusions of the right coronary artery and left anterior descending artery. He was successfully treated with drug-eluting stent implantation for both occluded coronary arteries. Such serious coronary lesions are uncommon for his young age. The patient was diagnosed as having antiphospholipid syndrome (APS) based on elevation of anticardiolipin antibody and anti-β2 glycoprotein I antibody. Two years after stent implantation, the patient was well without ischemia or thrombosis. APS should be considered a potential cause of serious coronary disease in young adults. .
