Abstract/OtherAbstract:
Large areas of non-functional but viable myocardium with reversible dysfunction are commonly seen in patients with acute myocardial infarction. Both reperfusion of acutely ischemic myocardium and chronic myocardial ischemia may produce a reversible forms of ventricular dysfunction. The two main conditions that lead to reversible myocardial dysfunction are stunned myocardium and hibernating myocardium. Myocardial stunning represents post-ischemic myocardial dysfunction that persists despite restoration of normal flow, with gradual return of contractile function. Hibernating myocardium is a state of persistently impaired myocardial function at rest due to reduced coronary blood flow owing to residual stenosis that can be restored toward normal by revascularization. The success of the revascularization procedures depends on the presence of amount of dysfunctional but viable myocardium. The basics and evaluation of reversible myocardial dysfunction are reviewed.
