急性心肌梗死患者医院感染临床分析

The correlation factor of hospital-acquired infection in patients with acute myocardial infarction

目的研究急性心肌梗死(AMI)患者医院感染的发生情况和相关因素,指导临床对AMI患者的治疗。方法回顾性分析254例AMI患者医院感染的发生率及其与性别、年龄、左室功能、心肌梗死部位、合并疾病、侵入性操作、抗生素应用等因素之间的关系。结果高龄、左室功能不全、前壁及多壁心肌梗死、延迟就诊、合并慢性肺部疾病和糖尿病等、侵入性操作均使医院感染发生增加(均P<0.01);发生医院感染的AMI患者有更高的病死率。结论预防性应用抗生素并不能减少医院感染的发生;积极控制好各项与医院感染有关的因素,减少感染的发生有助于提高AMI患者的生存率,从而提高AMI的救治水平。

Objective To investigate the circumstance of hospital-acquired infection in patients with acute myocardial infaretion（AMI）, analyse the correlation factors of hospital-aequired infeetion and guide the clinical treatment in AMI patients. Methods To retrospectively analyse the relation between the incidence rate of hospital-acquired infection and the factors such as sex, age, heart function, position of mycardiae infarction, complication, virulence operation, the use of antibiotics in 254 patients with AMI. Results The factors of advanced age, cardia insufficiency, anterior wall and multitude walks myeardiae infarction, delay visit, ehronicity pulmonary disease, diabetes mellitus, virulence operation could increase the ineidenee rate of hospital-acquired infection（ P 〈 0.01 ） ,the AMI patients with hospital-acquired infection had higher fatality rate. Conclusion The uses of preventive antibiotic can not reduce the incidence rate of hospital infection,actively control the correlation factors to hospital-acquired infection,and lower the incidence rate of hospital infection do benefit in raising the survival rate of AMI, shortening the length of stay and increasing the remedy level of AMI.
