Univariate and multivariate Cox regression analysis of variables associated with 30-day mortality.

CS cardiogenic shock; MAP Mean blood pressure, ADCHF acute decompensation of CHF, HR hazard ratio, CI confident interval, Lact/Chol Lactate/cholesterol, LDL low density lipoproteins, HDL high density lipoproteins, APACHE II acute physiology and chronic health evaluation II scoring system. *HRs of 30-day mortality outcomes adjusted for age and sex. = stepwise regression, significance level of the model P < 0.0001. †HR of patients in the highest quartile of Lact/Chol ratio (4th quartile Lact/Chol = 0.80 (95%CI, 0.66−1.90, n = 29); HR = 1, 1st −3rd quartile Lact/Chol = 0.33 (95%CI, 0.29−0.36, n = 97)).
