Data are shown as mean ± SD or n (%). Slow flow was defined as a reduced thrombolysis in a myocardial infarction (TIMI) flow grade of 2 or lower in coronary angiography. BMI, body mass index; CAD, coronary artery disease; hs-CRP, hypersensitive C-reactive protein; EF, ejection fraction; LA, left atrium; LVEDD, left ventricular end-diastolic diameter; LVESD, left ventricular end-systolic diameter; Lp (a), lipoprotein (a); PMI, periprocedural myocardial injury; SPAP, systolic pulmonary arterial pressure.
