*Variables with a p value <0.15 were submitted to multivariate
evaluation. APV = average peakflow velocity; CFR = coronary flow velocity reserve; cTfc = corrected TIMI frame count; LAD = left anterior descending coronary artery; LV = left ventricular; PCI = percutaneous coronary intervention; TIMI = Thrombolysis in Myocardial Infarction.
