NPPB and complication: Independent predictors of the development of CV complications in the first 3 months were diabetes mellitus (HR 2.490, p=0.014), V-POSSUM- physiology score (HR 1.179, p<0.001), V-POSSUM-morbidity (HR 1.032, p<0.001), V-POSSUM-mortality (HR 1.193, p=0.003), number of days spent in the ICU (HR 1.668, p<0.001), CK-MB (HR 1.006, p=0.001), NT pro-BNP (HR 5.482, p<0.001), and upper quartile of NT pro-BNP (HR 9.661, p<0.001) (Table 3).
