Abstract

Background Among rate-control or rhythm-control strategies, there is conflicting evidence as to which is the best management approach for non-valvular atrial fibrillation (AF) in elderly patients. Design We performed an ancillary analysis from the ‘Registro Politerapie SIMI’ study, enrolling elderly inpatients from internal medicine and geriatric wards. Methods We considered patients enrolled from 2008 to 2014 with an AF diagnosis at admission, treated with a rate-control-only or rhythm-control-only strategy. Results Among 1114 patients, 241 (21.6%) were managed with observation only and 122 (11%) were managed with both the rate- and rhythm-control approaches. Of the remaining 751 patients, 626 (83.4%) were managed with a rate-control-only strategy and 125 (16.6%) were managed with a rhythm-control-only strategy. Rate-control-managed patients were older (p = 0.002), had a higher Short Blessed Test (SBT; p = 0.022) and a lower Barthel Index (p = 0.047). Polypharmacy (p = 0.001), heart failure (p = 0.005) and diabetes (p = 0.016) were more prevalent among these patients. Median CHA2DS2-VASc score was higher among rate-control-managed patients (p = 0.001). SBT [odds ratio (OR) 0.97, 95% confidence interval (CI) 0.94–1.00, p = 0.037], diabetes (OR 0.48, 95% CI 0.26–0.87, p = 0.016) and polypharmacy (OR 0.58, 95% CI 0.34–0.99, p = 0.045) were negatively associated with a rhythm-control strategy. At follow-up, no difference was found between rate- and rhythm-control strategies for cardiovascular (CV) and all-cause deaths (6.1 vs. 5.6%, p = 0.89; and 15.9 vs. 14.1%, p = 0.70, respectively). Conclusion A rate-control strategy is the most widely used among elderly AF patients with multiple comorbidities and polypharmacy. No differences were evident in CV death and all-cause death at follow-up.
