A Case of Myocardial Infarction Occurred after Endoscopic Submucosal Dissection under Bridging Therapy with Low Molecular Weight Heparin

ABSTRACT

Myocardial infarction (MI) is a complication that can occur after endoscopic submucosal dissection (ESD). However, very few reports are available about this complication. A 71-year-old male, who had two drug eluting stents inserted due to ischemic heart disease, was referred to the Division of Gastroenterology for ESD of a lesion suspicious of early gastric cancer. ESD was performed after dual antiplatelet agents were discontinued and bridging therapy with low molecular weight heparin (LMWH) was initiated. However, MI occurred immediately after the ESD procedure. A coronary angiogram did not show any significant stent thrombosis or restenosis. The patient recovered spontaneously. Here, we report a case of MI that occurred after ESD under bridging therapy with LMWH.
