Box , Doha, Qatar. Some patients with chronic ischemic left ventricular dysfunction have shown significant improvements of contractility with favorable long-term prognosis after revascularization. Several imaging techniques are available for the assessment of viable myocardium, based on the detection of preserved perfusion, preserved glucose metabolism, intact cell membrane and mitochondria, and presence of contractile reserve. Nuclear cardiology techniques, dobutamine echocardiography and positron emission tomography are used to assess myocardial viability. In recent years, new advances have improved methods of detecting myocardial viability.

Myocardial Viability: What We Knew and What Is New

Metrics details. Percutaneous coronary interventions PCI in patients with ischemic systolic left ventricular dysfunction SLVD are routinely performed although their impact on prognosis remains unclear. Of note, PCI significantly reduced the symptom of angina from On the other hand, performing a stress testing before PCI seems to be associated with a more favorable outcome. Peer Review reports. Interestingly, a clearcut survival benefit of revascularization in comparison to medical treatment has never been demonstrated [ 4 — 7 ], Although benefits both on mortality and rate of hospitalization can be achieved with CABG [ 8 , 9 ], In addition, HF-REF patients with moderate-to-severe systolic dysfunction, i.

Background: Myocardial viability assessment in revascularization of ischemic heart failure remains controversial. This study evaluated the prognostic utility of cardiac magnetic resonance CMR late gadolinium enhancement LGE in ischemic heart failure. Analyses were stratified by treatment. Overall and anterior viability were assessed. Outcomes were all-cause mortality, cardiovascular CV mortality and major adverse CV events. A greater number of non-viable segments was significantly associated with higher all-cause and CV mortality in the CABG group adjusted hazard ratios 1. Anterior wall viability did not affect outcomes.

METHODS: In a substudy of patients with coronary artery disease and left ventricular dysfunction who were enrolled in a randomized trial of.

    The aim of revascularizing the infarct-related coronary artery IRCA is to restore interrupted or reduced blood flow, as well as to achieve some degree of functional recovery, avoid ventricular remodeling, and improve prognosis.
