Abstract
The purpose of this investigation was to define cardioversion success rates, frequency of complications of cardioversion, and current treatment practices in elderly patients (aged > or = 65 years) with atrial fibrillation (AF). The results were compared with those in younger patients (aged < 65 years). The investigation was a prospective multicenter observational study with 61 participating cardiology clinics. Consecutive patients in whom cardioversion of AF was planned had to be prospectively registered. Of 1,152 patients registered, 570 (49.5%) were < 65 years old (group 1) and 582 (50.5%) were > or = 65 years (group 2). The overall success rate of cardioversion on an intention-to-treat basis was 76.1% in group 1 and 72.7% in group 2 (p = 0.18). In multivariate analysis, left atrial size and New York Heart Association functional class before cardioversion were identified as predictors of success (p < 0.001, respectively; p = 0.025). These clinical factors were not equally distributed between the age groups: Left atrial size was larger in the elderly than in younger patients (44.0 +/- 6.4 mm vs 42.8 +/- 6.4 mm; p = 0.006) and a New York Heart Association functional class > or = II was more prevalent in group 2 than in group 1 ...Continue Reading
