  1. Categorical variables are expressed as absolute counts (%) and continuous variables as median (25th to 75th percentile). BMI = body mass index; CI: cardiac index; CPI: cardiac power index; LVEF = left ventricular ejection fraction; SCAI: Society for Cardiovascular Angiography and Interventions; SAPS = simplified acute physiology score; SOFA = sequential organ failure assessment; ICU = intensive care unit; VA-ECMO = venoarterial extracorporeal membrane oxygenation
  2. Values are median (1st quartile–3rd quartile) for continuous variables and n (%) for categorical variables
  3. *p value from Wilcoxon test for continuous variables and Fisher's exact test for categorical variables
