Unexpected Coronary Thrombosis Induced by Antiphospholipid Syndrome (hughes Syndrome): Case Report

UNEXPECTED CORONARY THROMBOSIS INDUCED BY ANTIPHOSPHOLIPID SYNDROME (HUGHES SYNDROME) CASE REPORT (Abstract): Antiphospholipid syndrome (APS), one of the most common states of acquired hypercoagulability, is diagnosed by the persistent presence of antiphospholipid antibodies and recurrent episodes of vascular thrombosis. We present the case of a 39-year-old man late-presenting for cardiac rehabilitation treatment after primary percutaneous coronary intervention (PCI) performed for anteroseptal myocardial infarction. He was a nonsmoker, with no prior personal history of other cardiovascular diseases (CVD) or cardiometabolic syndrome. The 60% thrombotic occlusion of the left anterior descending artery (LAD) leading to the acute cardiac event was the only abnormality that was found. The only etiological explanation was the late measurement and the positive tests for antiphospholipid antibodies. In young patients with no history of thrombotic disorder, such as cancer, cardiovascular or metabolic diseases, the unexpected onset of myocardial infarction by thrombotic coronary occlusion can be attributed to silent, undiagnosed autoimmune condition.
