Thrombotic complications of heparin-induced thrombocytopenia (HIT) can be devastating if not recognized and treated promptly. We describe an unusual case of rapid-onset HIT resulting in massive-bilateral pulmonary emboli in a 70 year-old man who developed chest pain during elective percutaneous coronary intervention (PCI). The diagnosis was made the following day after persistent chest pain and laboratory work demonstrating a new thrombocytopenia, a mildly elevated troponin, and positive DIC panel led to confirmatory imaging tests. HIT-related thrombosis should be considered in the differential diagnosis of chest pain in patients undergoing PCI.
