According to the Cox multivariable regression, the significant determinants of all-cause mortality were age (HR: 1.057; 95% CI: 1.047, 1.067), male gender (HR: 1.315; 95% CI: 1.064; 1.626), dementia (HR: 1.373; 95% CI: 1.045, 1.803), CRP value (HR: 1.004; 95% CI: 1.003, 1.005), ICU admission directly from the emergency department (HR: 1.759; 95% CI: 1.292, 2.395), and incident AF during hospitalization (HR: 1.405; 95% CI: 1.027, 1.992). This evidence concerns the gene CRP and atrial fibrillation.
