Abstract

AIMS

To determine the prevalence of atrial fibrillation (AF) in a population-based sample of adults.

METHODS AND RESULTS

Between January 2005 and December 2007 individuals aged > or =50 years, residents of the city of Geneva, who had participated in a previous random survey were invited for follow-up examination. AF was assessed on a single resting 6-lead ECG. Reported prevalences were standardized for the age distribution of Canton Geneva. Overall participation was 72.8%. Twenty-nine cases of AF (22 men) were diagnosed among 3285 subjects (1696 men). The crude prevalence of AF (95% CI) was 0.88% (0.86, 0.90) overall, but higher in men [1.30% (1.26, 1.34)] than in women [0.44% (0.41, 0.47)]. The age-standardized AF prevalence was slightly higher [overall: 0.94% (0.91, 0.97), men: 1.23% (1.19, 1.27), women: 0.54% (0.47, 0.61)]. AF prevalence increased with age in both sexes. A 'history of suspected arterial embolism' (brain or legs) was higher in the AF cases (10.3 vs. 3.3%; P = 0.03).

CONCLUSION

This population-based survey of a general Swiss population indicates that the prevalence of AF remains below 1%. These results are less alarming than those from previous studies based on patients seeking medical care.

摘要

目的

在一项基于人群的成年人样本中确定心房颤动（AF）的患病率。

方法和结果

在 2005 年 1 月至 2007 年 12 月期间，邀请年龄≥50 岁、居住在日内瓦市的、参加过先前随机调查的个体进行随访检查。在一次静息的 6 导心电图上评估 AF。报告的患病率按日内瓦州的年龄分布进行标准化。总体参与率为 72.8%。在 3285 名受试者（1696 名男性）中诊断出 29 例 AF（22 名男性）。AF 的总患病率（95%CI）为 0.88%（0.86，0.90），但男性更高[1.30%（1.26，1.34）]，女性较低[0.44%（0.41，0.47）]。年龄标准化的 AF 患病率略高[总人群：0.94%（0.91，0.97），男性：1.23%（1.19，1.27），女性：0.54%（0.47，0.61）]。两性的 AF 患病率均随年龄增长而增加。在 AF 病例中，“疑似动脉栓塞史”（脑或腿部）更高（10.3%比 3.3%；P=0.03）。
