Myocardial ischaemia may lead to impaired function of the myocardium. Chronic severe myocardial ischaemia may lead to hibernation, a vegetative state with long-lasting
dysfunction of the heart. Hibernation is a potentially reversible condition, which may respond to successful revascularization. If myocardial viability is proven, revascularization
of the myocardial territory in question might translate into improved subject prognosis. We present an overview of the existing literature on methods for detection of myocardial
viability, and the clinical effects of revascularization.
