Multivariate predictors of successful PCI. Results of hierarchical multivariate regression model modeling the probability of successful PCI (Thrombolysis in Myocardial Infarction [TIMI] III flow and 30-day survival). Model 1 adjusted for age, sex, BMI, systolic BP at baseline, number of pressors, cardiac arrest, intubated, lactate at baseline, prior CABG, and mechanical circulatory support. Model 2 adjusted for model 1 parameters + CardShock tertile (ref = tertile 3). Model 3 adjusted for model 2 + radial/femoral access (ref = femoral)
