We studied 49 consecutive coronary artery disease patients who bad left ventricular dysfunction to determine if dobutamine stress echocardiography is useful for identifying hibernating myocardium and predicting improvement in left ventricular functional recovery after coronary revascularization. Contractile reserve was identified in 24 patients. In a subset of 25 patients who underwent successful revascularization, nine of 11 with contractile reserve before revascularization had improved systolic wall thickening whereas 12 of 14 without contractile reserve showed no improvement, a significant difference. Dobutamine echocardiography is a simple, inexpensive method for identifying hibernating myocardium and predicting left ventricular functional recovery after coronary revascularization.
