IMPACT OF PRELIMINARY MYOCARDIAL VIABILITY ASSESSMENT ON REVASCULARIZATION OUTCOMES IN PATIENTS WITH REDUCED LEFT VENTRICULAR EJECTION FRACTION

Abstract

The article presents information about a research study conducted to investigate the outcomes of revascularization in patients with reduced left ventricular ejection fraction depending on myocardial viability. 416 patients with reduced LVEF were included in the study. Group I was prospective and included patients who underwent cardiac magnetic resonance imaging with delayed enhancement (192 patients). Group II was formed retrospectively, including 224 patients who underwent revascularization without myocardial viability detection. The clear improvement of left ventricular systolic function compared to preoperative data within each group by the follow-up was shown. The study results demonstrated that in both groups, left ventricular systolic function significantly improved regardless of the revascularization method, whether coronary artery bypass grafting (CABG) or percutaneous coronary intervention (PCI). That confirms the hypothesis of equal effectiveness of both revascularization strategies.
