At 30 days, diabetes (p = 0.01), urea (p < 0.05), Barthel index (p = 0.008), Charlson comorbidity index (p < 0.001), NT-proBNP (p = 0.001), and ST2 (p < 0.001) were all associated with the primary composite endpoint in the univariate analyses (Table 2). This evidence concerns the gene IL1RL1 and diabetes mellitus.
