In\u2010hospital mortality associated with IABP was examined in each SCAI shock stage. Multivariable logistic regression was performed using inverse probability of treatment weighting (IPTW) to determine the association between IABP and in\u2010hospital mortality.<\/jats:p><\/jats:sec><jats:sec><jats:title>Results<\/jats:title><jats:p>We included 934 patients, with a mean age of 68\u2009\u00b1\u200914\u2009years; 60% had ACS. The distribution of SCAI shock stages was: B, 41%; C, 13%; D, 38%; E, 8%. In\u2010hospital mortality was lower in the 39% of patients who received IABP (27% vs. 43%, adjusted OR with IABP after IPTW 0.53, 95% CI 0.40\u20130.72, p\u2009&lt;\u2009.0001). IABP use was associated with lower crude in\u2010hospital mortality in each SCAI shock stage (all p\u2009&lt;\u2009.05, except p\u00a0=\u00a0.08 in SCAI shock stage E).
