Abbreviations: AF, atrial fibrillation; BP, blood pressure; CI, confidence interval; Cr, creatinine; DM, diabetes mellitus; HR, hazard ratio; LVEF, left ventricular ejection fraction.

Data are presented as frequency of events (%) and HR (95% CI). In all analyses, the generalists group was taken as the reference group.

^aAdjusted for age, ischemic heart disease, hypertension, DM, AF, BP, race, sex, type of HF, imputed Cr, imputed heart rate, and imputed LVEF.

^bCox proportional hazards model was used to adjust for important potential confounders.
