Abstract

Abstract:

Objective To explore the relationship between ST-segment elevation in lead aVR(STEaVR) and SYNTAX score(SS) in patients with acute non-ST-segment elevation myocardial infarction(NSTEMI).Methods Totally 316 patients with NSTEMI were retrospectively analyzed. Overall clinical features, electrocardiograms(ECGs) ST elevation and depression in different leads of patients unpon admission, scores and peak values of left ventricle ejection fraction(LVEF), peak troponin Ⅰ level of the patients were counted and analyzed SS after coronary angiography. The patients with or without STEaVR were divied, the relationship between STEaVR and SS were explored.Results The number with STEaVR and without STEaVR in 316 patients was 207 cases (65.5%) and 109 cases (34.5%), respectively;the rate of patients with STEaVR gaining higher SS scores was higher when compared to those without STEaVR (50.7% vs 21.1%; P<0.01),and the incidence of left main coronary artery and/ or three-vessel disease (LM/3VD) was higher (43.5% vs 22.9%; P<0.01). Multivariate analysis showed the independent predictors for higher SS were STEaVR (OR=2.640, CI=1.404-4.963, P=0.003) and precordial ST-segment depression (OR=1.817, CI=1.053-3.135, P=0.032).Conclusion The main independent predictor for higher SS is STEaVR.
