Abstract

To determine independent predictors of left ventricular (LV) dyssynchrony after non-ST elevation myocardial infarction (NSTEMI) and prognostic value of combining dyssynchrony parameters for long-term LV dysfunction. Left ventricular dyssynchrony assessments were performed in 100 NSTEMI patients followed-up for 1 year using a composite dyssynchrony score. Early LV dyssynchrony was independently predicted by the presence of significant proximal left circumflex artery (LCx) stenosis and global systolic dysfunction. Left ventricular end-diastolic volume index decreased with time and was independently determined by a lower number of diseased vessels and the absence of early dyssynchrony. Left ventricular end-systolic volume index decreased with time and was independently determined by the absence of early dyssynchrony, lower number of diseased vessels, and revascularization. Left ventricular ejection fraction increased with time and was independently determined by the absence of early dyssynchrony, lower number of diseased vessels, and revascularization. The composite dyssynchrony score was an independent determinant of a persistently dilated LV and low LVEF at follow-up. After NSTEMI, proximal LCx stenosis and impaired LV function ...Continue Reading
