Noninvasive diagnosis of myocardial viability

Research output: Contribution to journalReview article

Abstract

Myocardial 'stunning' denotes a syndrome of severe regional contractile dysfunction that can occur following acute ischemic injury. Myocardial 'hibernation,' on the other hand, is a syndrome of chronic myocardial ischemic dysfunction resulting from sustained or repetitive episodes of relative hypoperfusion. Both stunned and hibernating myocardium represent viable tissue that can regain function following reperfusion therapy or revascularization. Recent investigations indicate that in patients with ischemic left-ventricular dysfunction, post-revascularization recovery of function influences subsequent functional status and prognosis. Using such noninvasive tests as thallium-201 or technetium-99m perfusion imaging or positron emission tomography, it is now possible to prospectively identify acutely stunned or chronically hibernating myocardium.
