HR = hazard ratio, CI = confidence interval, CK-MB = creatine kinase myocardial band, hs-CRP = high-sensitivity C-reactive protein, LVEF = left ventricular ejection fraction, NLR = neutrophil-to-lymphocyte ratio, PCI = percutaneous coronary intervention, TIMI = thrombolysis in myocardial infarction.
