A case of dobutamine-induced coronary arterial spasm with ST-segment elevation.
A 55-year-old Japanese woman demonstrated ST-segment elevation in leads I, aVL, and V3-V6 with chest pain both in an ergometer exercise test and on dobutamine stress echocardiography. Although the baseline coronary arteriogram revealed no organic stenosis, total occlusion of the distal portion of the posterolateral branch of the left circumflex artery was observed during dobutamine infusion with ST-segment elevation and chest pain. This is a rare case of documented dobutamine-induced coronary arterial spasm.
