Clinical features of nosocomial infections in patients with acute myocardial infarction after percutaneous coronary intervention

目的探讨急性心肌梗死急诊冠脉介入术后住院患者医院感染的临床特征。方法回顾性调查分析2007年1月-2009年12月225例急性心肌梗死急诊冠脉介入术后住院患者的临床资料。结果急诊冠脉介入术后心肌梗死住院患者感染率为28.44%,感染部位以呼吸道感染多见,占74.99%,其次为消化道,占9.38%,泌尿道感染占9.38%;年龄、住院天数、合并糖尿病、慢性支气管炎、心功能不全（3~4级）、广泛前壁心肌梗死、多支病变是医院感染发生的相关危险因素。结论急性心肌梗死急诊冠脉介入术后住院患者医院感染有一定的发生率,有其临床特征,临床需引起注意,及时预防及治疗医院感染的发生。

OBJECTIVE To evaluate the clinical features of nosocomial infections in acute myocardial infarction（AMI） patients after percutaneous coronary intervention（PCI）.METHODS A retrospective study was carried out to investigate the clinical data of 225 inpatients with post-PCI AMI from Jan 2007 to Dec 2009.RESULTS The incidence of nosocomial infections of after PCI was 28.44%,the most common was in respiratory tract（74.99%）,followed gastrointestinal tract infection（9.38%）and the urinary tract infection（9.38%）.The infection was closely related with patient′s age,duration of hospitalization,diabetes,COPD,severe heart failure（NYHA Ⅲ-Ⅳ） and multivessel disease.CONCLUSION The nosocomial infection with AMI post-PCI has a certain incidence and its own features and needs the special attentions.Prevention and proper treatments can prevent the occurrence of nosocomial infection.
