目的：了解克拉玛依炼油厂社区居民慢性心力衰竭的患病率及其危险因素。方法采用整群随机抽样法抽取2007年10月－2010年3月克拉玛依炼油厂社区年龄＞35岁常住成人作为调查对象，统计不同民族、不同性别、不同年龄段人群的慢性心力衰竭患病率，对危险因素进行分析。以问卷收集资料并进行体格检查及实验室检查。结果共抽取年龄＞35岁汉族、维吾尔族及哈萨克族居民3821人，慢性心力衰竭的患病率为0．3％，男性心力衰竭患病率为0．4％，女性为0．2％，男性高于女性。汉族慢性心力衰竭患病率为0．4％，汉族慢性心力衰竭患病率高于维吾尔族及哈萨克族；男性各年龄组间慢性心力衰竭患病率差异有统计学意义（P ＜0．05），并且慢性心力衰竭的患病率均随年龄的增长而增高。结论新疆慢性心力衰竭患病率存在民族差异。对新疆不同民族人群的心衰的流行病学调查对于高危人群进行早期社区干预及减少患病率、再住院率及死亡率具有重大意义。
