Myocardial dysfunction due to chronic hypoperfusion (so-called hibernating myocardium) is potentially reversible if the normal coronary flow is restored. Stress echocardiography (dobutamine, post-extrasystolic potentiation) may elicit contractile reserve of the hibernating myocardium and predict accurately its functional recovery after coronary revascularization. Thus, the identification of dysfunctioning but viable myocardium may be crucial to select patients with ischemic congestive heart failure who might benefit from coronary revascularization.

Abstract
Myocardial dysfunction due to chronic hypoperfusion (so-called hibernating myocardium) is potentially reversible if the normal coronary flow is restored. Stress echocardiography (dobutamine, post-extrasystolic potentiation) may elicit contractile reserve of the hibernating myocardium and predict accurately its functional recovery after coronary revascularization. Thus, the identification of dysfunctioning but viable myocardium may be crucial to select patients with ischemic congestive heart failure who might benefit from coronary revascularization.File in questo prodotto:
