Relation of cardiac prognosis to segment location with apical left ventricular ischemia

Am J Cardiol. 2003 Nov 15;92(10):1206-8. doi: 10.1016/j.amjcard.2003.07.033.

Abstract

Previously, we have shown that myocardial ischemia induced during intravenous dobutamine in the distal segments composing the left ventricular apex is associated with a heightened risk of future myocardial infarction or cardiac death. In this study, we find this heightened risk is present independent of the location of the distal segment within the left ventricular apex.
