*, Early outcomes are given as OR; long-term outcomes are given as HR. **, Cox proportional hazards assumption (by Schoenfeld residuals): all-cause death (P=0.096), MACE (P=0.093) and Death + MACE (P=0.883). OR, odds ratio; HR, hazard ratio; CI, confidence interval; IPTW, inverse probability of treatment weighting; LCOS, low cardiac output syndrome; MCS, mechanical circulatory support; MACE, major adverse cardiac event.
