In the multivariate Cox model adjusted for hypertension, smoking, troponin I, NT-proBNP, and creatinine level, independent predictors of atrial arrhythmias included: age ≥60 years (HR = 10.25, 95% CI: 1.01–104.56, P = 0.049), anthracycline use (HR = 2.70, 95% CI: 1.02–7.19, P = 0.045), eGFR <60 mL/min/1.73m2 (HR = 2.58, 95% CI: 1.04–6.39, P = 0.039), and diabetes duration ≥5 years (HR = 2.85, 95% CI: 1.22–6.70, P = 0.016) (Table 5). Here, NPPB is linked to diabetes mellitus.
