Values are expressed as mean and standard deviation or percentages with counts as indicated. CPR indicates cardiopulmonary resuscitation; CS, cardiogenic shock; ECMO, extracorporeal membrane oxygenation; IABP, intra‐aortic balloon pump; ICU, intensive care unit; LCOS, low cardiac output syndrome; MACCE, major adverse cardiocerebral events; NSTEMI, non–STsegment–elevation myocardial infarction; PMI, perioperative myocardial infarction; RBC, red blood cell unit transfusion; STEMI, ST‐segment–elevation myocardial infarction.
