Abstract

Substantial progress has been made in understanding the pathophysiology of regional and global left ventricular (LV) dysfunction and the states of hibernation and stunning in patients with heart failure. The clinical literature on the use of noninvasive imaging to assess myocardial viability has evolved from predicting improvement in regional LV function to predicting patient-related outcomes, including heart failure symptom improvement and survival after revascularization. A substantial body of observational cohort data demonstrates that mortality risk is high in patients with coronary artery disease and LV dysfunction who have substantial viable myocardium, and that risk is reduced by revascularization. Thus, noninvasive imaging of myocardial ischemia and viability can provide important prognostic information in patients with heart failure and LV dysfunction, and provide a signal of the potential benefit of revascularization.

J Am Coll Cardiol 2002, 39:1151–1158. Meta-analysis of over 20 studies examining the relation of the presence or absence of viability and the influence of revascularization versus medical therapy on survival in patients with LV dysfunction. Demonstrated that patients with preserved viability are at high risk during follow-up on medical therapy, a risk that appeared to be lowered by revascularization. There appeared to be no advantage to revascularization in the absence of significant viability.

Circulation 1998, 98:II51-II56. This important study demonstrated that patients with hibernating myocardium may benefit less from revascularization if the procedure is delayed, suggesting that hibernation is not a stable steady-state adaptation, but rather a high-risk state.
