    Background: We aimed to evaluate possible association between QRS duration (QRSD), R wave peak time (RWPT), and coronary artery disease severity identified using the SYNTAX score (SS) in patients with unstable angina pectoris (USAP) or non-ST segment elevation myocardial infarction (NSTEMI). Method: A total of 176 USAP/NSTEMI patients were enrolled in the study. Results: The high SS group (>22, n:45) patients had a higher prevalence of diabetes mellitus (DM); presence of ST segment depression >= 0.5 mm and 1 mm; ST segment elevation in the AVR lead (AVRSTE); longer QRSD and RWPT; and lower left ventricular ejection fraction (LVEF) than the low SS group (22, n: 131). The LVEF, AVRSTE, and RWPT (OR: 1.035, 95% CI: 1.003-1.067; p = 0.030) were independent predictors of high SS. Conclusion: The present study demonstrated that RWPT and AVRSTE could be used as predictors of high SS. (C) 2017 Elsevier Inc. All rights reserved.
