老年心房纤颤312例患者相关危险因素分析

目的探讨心房纤颤（房颤）患者的相关危险因素,旨在防止房颤的发生。方法对我院2007年1月~2009年12月312例老年人房颤患者住院资料进行回顾性分析,并按年龄分组,分析老年人房颤的危险因素。结果 312例房颤患者中,男162例（51.9%）,女150例（48.1%）,年龄60~107岁,平均（74.78±8.34）岁。其中60~69岁的患者35例（11.2%）,70~79岁的患者130例（41.7%）,〉80岁的患者147例（47.1%）。同期全院住院患者5362例,不同年龄组分别为：60~69岁的患者1254例,70~79岁的患者2420例,〉80岁的患者1688例。房颤患者占同年龄组住院患者的比例依次为35例（2.8%）、130例（5.4%）、147例（8.7%）;312例房颤患者,阵发性、持续性、永久性房颤患者分别为74例（23.7%）、33例（10.6%）、205例（65.7%）;基础疾病高血压占首位,其次为心功能不全、冠心病、慢性肺疾病、糖尿病、退行性钙化瓣膜病等。随年龄的增加房颤的发病率明显增加,同时312例房颤患者的左房内径与同年龄组同时期非房颤的302例患者的比较差异有统计学意义（t=16.79 P〈0.05）。而且房颤、心力衰竭、左房内径三者互为因果。结论房颤的发生随增龄而明显增加。高血压、心功能不全、冠心病、慢性肺疾病、糖尿病、退行性钙化瓣膜病、肾功能不全、风湿性心脏病均是房颤的危险因素,应早期预防、控制和治疗,以防止房颤的发生。

Clinical analysis of related risk factors in 312 elderly hospitalized cases with atrial fibrillation

Objective To investigate the related risk factors in patients with atrial fibrillation in order to prevent and delay the occurrence of atrial fibrillation.Methods Three hundred and twelve elderly inpatients with atrial fibrillation were retrospectively analyzed from January 2007 to December 2009.They were divided into several groups according to the age and the characteristics of the elder patients with atrial fibrillation were analyzed.Results In the 312 cases with atrial fibrillation,there were 162 males（51.9%） and 150 females（48.1%） aged from 60 to 107 years.the average age was（74.78±8.34） years.There were 35 cases aged 60~69 years（11.2%）,130 cases aged 70~79 years（41.7%）,147 cases aged over 80 years（47.1%）.The total number of inpatients in our hospital was 5362,and there were 1254 cases aged 60~69 years,2420 cases aged 70~79 years and 1688 cases aged over 80 years.The proportions of the inpatients with atrial fibrillation in the above three age groups of inpatients were 2.8%（35 cases）,5.4%（130 cases） and 8.7%（147 cases）,respectively.In 312 cases with atrial fibrillation,there were 74 cases（23.7%） with paroxysmal atrial fibrillation,33 cases（10.6%） with persistent atrial fibrillation and 205 cases（65.7%） with permanent atrial fibrillation.The most common underlying disease was hypertension in the 312 cases,followed by heart failure,coronary heart disease,chronic pulmonary disease,diabetes,senile degenerative calcific valvular disease,rheumatic heart disease and so on.A morbility rate of atrial fibrillation increases with age.There is to be differences in left atrial diameter among patiens with atrial fibrillation and patiens having no atrial fibrillation,and these differences have statistical significance（t=16.79,P0.01）.atrial fibrillation,left atrial diameter and heart failure are mutully causal and resultant.Conclusion The prevalence of atrial fibrillation is increased with aging.Hypertension,heart failure,coronary heart disease,chronic pulmonary disease,diabetes,senile degenerative calcific valvular disease,renal failure,rheumatic heart disease and hyperthyroidism,are all the risk factors atrial fibrillation.
