Abstract
During dobutamine stress echocardiography, ST-segment elevation developed in 20 of 372 patients (5%) without previous myocardial infarction and was associated with a transient severe asynergy of the myocardial region corresponding to the site of ST elevation. In 17 of 19 patients, ST-segment elevation was associated with a critical stenosis of the ischemia-related coronary artery, whereas in 2 of 19 patients with no critical lesions of the ischemia-related artery, coronary vasospasm was the most likely mechanism of myocardial ischemia.
