绵竹市农村成人心房颤动流行现况及危险因素

Adults Atrial Fibrillation and Relative Risk Factors in Rural Area of Mianzhu City

目的了解绵竹市农村成年人群中心房颤动(房颤)流行现状及相关危险因素,为心脑血管疾病的防治提供科学依据。方法应用整群随机抽样方法抽取2个镇、10个村、35岁以上农村居民2083人,进行以房颤为主要内容的心血管流行病学调查。结果该人群平均房颤患病率为0.8%,单因素分析房颤患病率男性大于女性,随年龄增长而增长;极轻体力劳动组明显高于其余各组;有心脏病史、现症高血压者高于正常组,房颤组脉率低于非房颤组、脉律不齐者房颤患病率为17.9%;脑卒中与房颤的发生关系密切。多因素Logistic回归分析结果显示,年龄、心脏病史、脑卒中史和脉律不齐与房颤患病率的OR值分别为1.081、16.357、26.048、15.966。结论房颤患病率与国内有关研究结果接近,年龄、心脏病史、脑卒中史、血压水平等是房颤的主要相关危险因素,需要加强对房颤的控制。

Objective To get the information about the current situation and relative risk factors of atrial fibrillation among adults in the rural area of Mianzhu City, and to provide scientific evidences for the prevention and treatment of cardio-cerebro vascular disease. Method By means of cluster sampling, 2 083 rural habitants aged over 35 year old were selected from 10 villages of 2 towns among who a cardio-vascular epidemiology investigation focusing on atrial fibrillation was carried out. Results The average prevalence of atrial fibrillation was 0. 8%. According to the single factor analysis, the prevalence of male was higher than that of female, and the prevalence tends to rise with the increase of the age. The prevalence of the group of very light manual labor workers was apparently higher than that of the other groups. The prevalence of those with the record of heart disease and those suffering from high-blood pressure was higher than that of the normal group. The pulse of the atrial fibrillation group was lower than that of the other groups, and the prevalence of atrial fibrillation among those with arrhythmia was 17.9%. The prevalence of atrial fibrillation was closely related to cerebral stroke. According to the multi-factor logistic analysis, the OR value between atrial fibrillation and age, heart disease, cerebral stroke and arrhythmia was 1. 081, 16. 357, 26. 048, and 15. 966, respectively. Conclusion The prevalence of atrial fibrillation of the sample is close to the result of domestic relative researches, and the main relative risk factors of atrial fibrillation are age, record of heart disease, record of cerebral stroke, and blood pressure, etc. Therefore, it is advisable to strengthen the control of atrial fibrillation.
