Data are presented as mean ± SD or number (%) of subjects. TIMI: thrombolysis in myocardial infarction; CTFC: corrected TIMI frame count; PCI: percutaneous coronary intervention; CTFC post1: CTFC immediately after stent deployment: CTFC post2: CTFC at the end of PCI; CK: creatine kinase, TNI: troponin.
