Electric Shock-Induced Coronary Artery Thrombosis and Dissection

Abstract

Electric shock-induced myocardial infarction is rare. Shock-induced coronary artery thrombosis and dissection in multiple distributions have not been reported. After shock, coronary thrombosis may cause anginal symptoms, and any coronary artery may be damaged. A 32-year-old man presented with angina and ischemia-related symptoms after 6,000-V electric shock. He reported occasional exertional angina; the stress echocardiography result was positive for ischemia. Cardiac catheterization showed severe multivessel disease, an occluded left anterior descending coronary artery, and an occluded circumflex artery with collateralization to the distal left anterior descending coronary artery. Surgical intervention detected global coronary dissection and thrombosis. Bypass grafting achieved complete revascularization. The patient was successfully discharged home.
