Heart rate following short-term beta-blocker titration predicts all-cause mortality in elderly chronic heart failure patients: insights from the CIBIS-ELD trial.

Abstract：

AIMS:Beta-blockers (BBs) improve outcomes in heart failure. Results from the Cardiac Insufficiency Bisoprolol Study in Elderly (CIBIS-ELD) trial previously demonstrated the feasibility of heart rate, not maximum dose, as a treatment goal. In this pre-specified analysis, we investigated the prognostic value of achieved heart rate after BB optimization on long-term mortality. METHODS AND RESULTS:Elderly heart failure patients from the CIBIS-ELD trial were invited to participate in a follow-up examination 4 years after the initial 12-week BB up-titration period. The relationship between all-cause mortality, BB dose, and heart rate after titration and potentially confounding clinical variables was analysed by multivariable Cox regression. In total, 728 patients (38% women; mean age 72.9 ± 5.4 years) were included. During a mean follow-up period of 45 ± 9 months, 134 patients (19%) died, thus accumulating 2268 patient-years at risk. There was no significant difference in baseline heart rate for survivors and non-survivors (P = 0.19). In models adjusting for age, sex, BB pre-treatment, ventricular function, heart rate, and NYHA class at baseline, a heart rate increase by 10 b.p.m. following up-titration was associated with a subsequent mortality hazard ratio of 1.19 (95% confidence interval 1.02-1.38, P = 0.023). The heart rate range with the lowest mortality and the fewest treatment-related adverse events was 55-64 b.p.m. The achieved BB dose was not associated with mortality risk. CONCLUSION:The heart rate after up-titration, but not BB dose, predicted all-cause mortality risk in elderly patients with chronic heart failure. These patients should be titrated to resting heart rates between 55 and 64 b.p.m.
