ACS indicates acute coronary syndrome; CS, cardiogenic shock; EuroSCORE, European System for Cardiac Operative Risk Evaluation; LVEF, left ventricular ejection fraction; NSTEMI, non–ST‐segment–elevation myocardial infarction; OR, odds ratio; PCI, percutaneous coronary intervention; STEMI, ST‐segment–elevation myocardial infarction; ULN, upper limit of normal.
