CV, cardiovascular; HF, heart failure; IMR, index of microcirculatory resistance; MACE, major advanced cardiac events; MI, myocardial infarction; TLR, target lesion revascularization. MACE was defined as composite of CV death, hospitalization because of HF, TLR, stent thrombosis, nonfatal MI, stroke, and major bleeding.
