Acute ST-segment elevation myocardial infarction due to extrinsic compression of left coronary artery from pulmonary epithelioid hemangioendothelioma: A case report
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. 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. 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. The patient did not undergo further therapy after the pulmonary nodulectomy. During the present hospitalization, she received basic life support and nutritional support treatment. The patient deteriorated rapidly into multi-organ failure and eventually died. 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.
