1、冠心病放置支架后监护期发生心律失常的危险因素分析［摘要］目的分析冠心病放置支架后令0护期发生心律失常的危险因素。方法回顾性分析大连大学附属新华医院2013年1月〜2015年6月收治的264例因冠心病需放置支架的患者资料。将所有患者根据不同临床因素进行分类，先用单因素分析法分析不同条件下患者发生心律失常的比例差异，再进行多因素Logistic回归分析，得出冠心病患者放置支架后在监护期发生心律失常的危险因素。结果264例冠心病放置支架患者中有73例在监护期发生心律失常，比例为27.65%。经Z2检验显示，年龄＜65

2、岁、术前心功能分级为I〜II级、术前左室射血分数＜50%、无高血压、无高血脂、无糖尿病、无慢性阻塞性肺疾病、无吸烟史、放置支架数量为1个以及术中不进行体外循环的条件下发生心律失常的比例低于同因素对立条件下发生心律失常的比例。多因素Logistic回归分析结果，年龄、术前心功能分级、LVEF、高血脂、COPD、支架数量是冠心病放置支架患者在监护期发生心律失常的独立危险因素。结论年龄、术前心功能分级、术前LVEF、高血脂、COPD、支架数量均会影响冠心病患者在置入支架术后发生心律失常的概率。［关键词］冠心病；支架置
