Abstract
aVR(-) groups in the rate of TIMI flow grade of 0-2, inhospital percutaneous coronary intervention and in-hospital MACE. With the use of multivariate analysis in all studied population, ST depression was strongly associated with multivessel disease (odds ratio [OR] 1.90; 95% confidence interval [CI] 1.05 to 3.48; p1⁄40.034). However, ST elevation in lead aVR lost its statistical significance (OR 1.84; 95% CI 0.93 to 3.70; p1⁄40.082). CONCLUSION: In NSTEMI patients without ST depression, ST elevation in lead aVR has a predictive value for multivessel disease and in-hospital CABG. However, ST depression carries a stronger predictive value for multi-vessel disease and ST elevation in lead aVR lost its statistical significance in the presence of coexisting ST depression.
