myocardial viability, myocardial infarction, cardiovascular magnetic resonance, myocardial revascularizationAbstract
Background: Myocardial infarction initiates a dynamic continuum of ischemic injury ranging from transient contractile dysfunction to irreversible necrosis and replacement fibrosis. Although rapid reperfusion remains the principal determinant of myocardial salvage, the relationship between symptom duration and tissue viability is not absolute. Intermittent coronary occlusion, spontaneous reperfusion, residual antegrade flow, ischemic preconditioning, collateral circulation
