Abstract
Rationale:Acute myocardial infarction is usually caused by coronary atherosclerotic plaque disruption (rupture or erosion), also including other uncommon etiologies. Pulmonary epithelioid hemangioendothelioma (PEH) is a rare low to intermediate malignant vascular tumor originating from vascular endothelial cells. Here, we report a rare case of acute ST-segment elevation myocardial infarction (STEMI) due to extrinsic compression of left coronary artery from PEH.Patient concerns:A 63-year-old woman with pulmonary nodules received left pulmonary nodulectomy, and the pathological examination indicated PEH. Five months after the pulmonary nodulectomy, the patient was admitted due to progressive dyspnea.Diagnosis:Electrocardiography showed the obvious ST-segment elevation in the leads I, aVL, and V1–3, and laboratory tests revealed the elevated level of cardiac troponin T. Emergent coronary angiography and the contrast-enhanced computed tomography scan conformed STEMI due to extrinsic compression of left coronary artery from PEH.Interventions:The patient did not undergo further therapy after the pulmonary nodulectomy. During the present hospitalization, she received basic life support and nutritional support treatment.Outcomes:The patient deteriorated rapidly into multi-organ failure and eventually died.Lessons:Acute STEMI could be caused by extrinsic compression of the coronary artery from the mass effects of PEH, and active therapy and close follow-up should be considered for patients with PEH.
