Data are presented as the mean ± standard deviation, n (%), and median (IQR). Fisher’s exact test. IABP = intra-aortic balloon pump; LVEF = left ventricular ejection fraction; RCA = right coronary artery; NOAC = novel oral anticoagulants; NSTEMI = non-ST-elevation myocardial infarction; and UGI = upper gastrointestinal bleeding.
