ABSTRACT
AIMS:
Prior studies have reported conflicting results on digoxin's impact on clinical outcomes and quality of life, and there are limited data from Asia. The aim of this study is to evaluate the use of digoxin and its impact on clinical outcomes and quality of life in a high-risk cohort of elderly Chinese atrial fibrillation (AF) patients. METHODS ANDRESULTS:
The Optimal Thromboprophylaxis in Elderly Chinese Patients with Atrial Fibrillation (ChiOTEAF) registry is a prospective, multicentre nationwide study conducted from October 2014 to December 2018. Endpoints of interest were the composite outcome of all-cause death/any thromboembolism (TE), all-cause death, cardiovascular death, sudden cardiac death, and TE events, as well as the quality of life. The eligible cohort for this analysis included 6391 individuals, of whom 751 (11.8%) patients were treated with digoxin. On multivariate analysis, the use of digoxin was associated with a higher odds ratio (OR) of composite outcome [OR 1.71; 95% confidence interval (CI) 1.32-2.22], all-cause death (OR 1.62; 95% CI 1.23-2.14), and any TE (OR 1.78; 95% CI 1.08-2.95). Results were consistent in a subgroup of patients with diagnosed heart failure (HF) and patients with permanent AF. The use of digoxin was associated with worse health-related quality of life (mean EQ index 0.76 ± 0.19 vs. 0.84 ± 0.18; P < 0.001).CONCLUSIONS:
In this nationwide cohort study, digoxin use was associated with an overall higher risk of the composite outcome of all-cause death/any TE, all-cause death, and any TE, regardless of HF diagnosis. Patients treated with digoxin had a worse health-related quality of life.Palavras-chave
