Antiphospholipid antibody syndrome (APLS) is well known to cause thrombotic events and premature atherosclerosis leading to coronary artery occlusion. The association of non-thrombotic acute myocardial infarctions (AMI) with APLS is not as clearly delineated. The objective of this study was to determine the relative prevalence of myocardial infarction with non obstructive coronary arteries (MINOCA) compared to MI from vaso-occlusive disease amongst patients with known APLS at our institution. Out of 575 patients with positive antiphospholipid antibodies, cardiac catheterizations were performed in 40 patients presented with AMI and had cardiac catheterizations. MINOCA was found in 8 patients. We found that MINOCA is common in patients with APLS presenting with ACS and that spasm may also play a role in AMI in patients with APLS.
