AMICS—acute myocardial infarction-associated cardiogenic shock; BMI—body mass index; CKD—chronic kidney disease; CMP—cardiomyopathy; CS—cardiogenic shock; eCPR—extracorporeal cardiopulmonary resuscitation; MAP—mean arterial pressure; PCCS—postcardiotomy syndrome cardiogenic shock; RRT—renal replacement therapy; stMCS—short-term mechanical circulatory support; v-a ECLS—venoarterial extracorporeal life support; VI score—vasoactive–inotropic score. Data are presented as number (%) or mean {SD}. Data followed by square brackets show the median with interquartile range. Grey highlighted fields indicate significantly differing results, assumed by a p-value < 0.05.
