老年肺部感染并发非ST段抬高性心肌梗死的临床特征分析

Analysis of Clinical Characteristics of Lung Infection Complicated with Non-ST Elevated Myo-cardial Infarction in Elderly Patients

【目的】分析老年肺部感染与急性心肌梗死的发病关系，了解老年肺部感染与非ST段抬高性心肌梗死（NSTEMI）的相关性。【方法】回顾性分析297例年龄〉75岁的老年肺部感染患者胸片、心电图检查、血气分析、心肌酶谱及治疗等多个项目资料，分析其发生NSTEMI的比率。【结果1297例肺部感染的老年患者，其中低危患者177例中34例患者并发NSTEMI，占19．21％（34／177）；高危患者120例中36例患者并发NSTEMI，占30．0%。％（36／120），两者相比较差异有显著性（P〈0．05）。【结论】对伴肺部感染的老年患者要警惕并发NSTEMI，特别是有高危因素的患者更应引起高度重视并及时确诊治疗。

[Objective] To analyze the relationship between lung infection and acute myocardial infarction in elderly patients so as to understand the correlation between lung infection and non-ST elevated myocardial infarction（NSTEMI）. [Methods] The different manifestations, chest film, electrocardiogram, blood gas anal- ysis, myocardial enzymes and treatment of 297 elderly patients with lung infection were studied retrospective- ly. The incidence of NSTEMI was analyzed. [Results] Of 297 elderly patients admitted to hospitalization due to lung infections, 34 patients in 177 low-risk patients were complicated with NSTEMI, accounting for 19.21%0 （34/177）, and 36 patients in 120 high-risk patients were complicated with NSTEMI, accounting for 30.00%（36/120）. There was significant difference between high-risk patients and low-risk patients（ P〈0.05）. [Conclusion] Elderly patients with lung infection should be cautious to be complicated with NSTEMI. Especially high-risk patients should be highly paid attention, and diagnosed and treated timely.
