Abstract:
:The prediction of significant left main or diffuse three-vessel coronary artery disease is crucial in patients presenting with an acute coronary syndrome. ST-segment elevation in aVR has been reported to be associated with left main coronary artery obstruction or severe diffuse coronary artery disease in acute coronary syndrome. Herein we report another cause for this ECG finding, that is diffuse ischemia not due to left main coronary artery obstruction or diffuse coronary artery disease but secondary to prolonged hypotension.
