858例老年人心房颤动患病率的调查

An investigation into prevalence of atrial fibrillation in 858 elders

目的调查老年人房颤的患病率及其转归。方法于2005年6～7月对在该院进行健康体检的老年人进行问卷调查、体格检查和心电图检查。结果858例年龄60￣99岁平均(75.6±6.6)岁的老年人,房颤患者76例,患病率8.9%,80岁年龄组房颤患病率高达25.0%,显著高于其他年龄组(P<0.001)。阵发性房颤转为永久性或持续性房颤的发生率为24.2%,胺碘酮对阵发性房颤复律总有效率为83.3%,无患者发生脑卒中,调查对象57.9%接受了抗血小板治疗。结论房颤是老年人常见的心律失常,患病率随年龄增长显著增高,冠心病是老年人房颤最主要的病因,胺碘酮转复老年人房颤安全有效,抗血小板治疗能显著降低脑卒中发生率。

[Objective] To investigate the prevalence and prognosis in elderly patients with atrial fibrillation （AF）. [Methods] We performed the questionnaire, health checkup and ECG on the elders who came to our hospital for medical examination from June to July in 2005. [Results] Among the 858 cases who were from 60 to 99 years old in whom the average was （75.6±6.6）, 76 AF cases existed, and the prevalence was 8.9%, especially, the prevalence in over 80 years old group was up to 25.0%, which was significantly higher than that of the other groups （P 〈 0.001）. The rate of paroxysm AF transformed into perpetual AF or lasting AF was 24.2%. The total effectual rate of restoring AF after taking amiodarone was 83.3%, no case of stroke happened, and 57.9% of the 858 cases were ac- cepted antiplatelet treatment. [Conclusions] AF is one of the most frequent type of arrhythmia in the elders. The prevalence is obviously increasing with aging, and coronary heart disease is the main cause of the eider AF cases. Amiodarone can safely and effectively restore the elder AF; accepting antiplatelet treatment can noticeably reduce the incidence of stroke.
