Comparison of rate and rhythm control in patients with atrial fibrillation and nonischemic heart failure.

摘要: Atrial fibrillation (AF) is a very common cardiac arrhythmia with an increased mortality in patients heart failure. Whether the best therapeutic approach to these restore sinus rhythm or adequately control ventricular rate still controversial. The aim of this study was compare both strategies AF and nonischemic One hundred fifty-four duration greater than 48 hours left dysfunction were randomized either (n = 84) 74) group. composite end points embolism, death, exercise capacity. average age 61 ± 10 years group 58 12 (P NS). follow-up period 35 21 months 37 19 In first year study, capacity ejection fraction (LVEF) improved compared LVEF < 0.0001 P 0.0005, respectively). There no statistically significant differences embolic event between two groups rate, especially for death due pump failure, significantly higher at 0.0001). Restoring maintaining had beneficial effect on failure AF.
