摘　　要：目的:探讨慢性心力衰竭患者合并肺部感染的特点。方法:回顾性分析44例慢性心力衰竭合并肺部感染患者的临床资料,观察肺部感染的临床表现、痰培养、肺部感染相关因素及对预后的影响。结果:具有典型症状20例,表现非特异者17例,无症状者7例;痰培养结果包括革兰氏阴性菌33株次、革兰氏阳性菌12株次、真菌8株次;肺部感染组年龄(64.87±11.67)岁、NYHA-分级(2.51±0.29)、实施有创检查或治疗59.09%、应用制酸剂72.72%、预防应用抗生素56.82%高于无肺部感染组的(58.22±12.80)岁、(1.98±0.43)、22.73%、45.45%、18.18%(P<0.05),是引起肺部感染的危险因素。合并肺部感染患者住院(25.03±7.56)天,死亡率15.91%高于无肺部感染组(16.44±4.23)天,2.27%(P<0.05)。结论:慢性心力衰竭患者肺部感染难以完全避免,临床表现不典型,病原菌构成复杂,影响因素多样,对预后有不良影响,应实施相应的措施预防肺部感染的发生。Objective：To investigate the characteristics of pulmonary infection in patients with chronic heart failure. Methods：Retrospective analysis the clinical data of chronic heart failure with pulmonary infection 44 patients, clinical manifestations of pulmonary infection, sputum culture, related factors of pulmonary infection and influence on prognosis. Results：20 cases had typical symptoms, 17 cases were non-specific, 7 cases with no symptoms;sputum culture results including gram negative bacilli 33 isolates, Gram-negative bacteria12 strains, fungi 8 strains;the age of lung infection （64.87±11.67） years, NYHA-grade （2.51±0.29）, implementation acheck or treatment 59.09%, use of antacids 72.72%, prophylactic use antibiotics 56.82%higher than those without pulmonary infection group （58.22±12.80）, （1.98±0.43）, 22.73%, 45.45%, 18.18% （P〈0.05）, is caused risk factors of pulmonary infection. Patients with lung infection （25.03±7.56） days, the mortality rate was 15.91%higher than that without pulmonary infection group （16.44±4.23） days, 2.27%（P〈0.05）.Conclusion：It is difficult to completely avoid infection in patients with chronic heart failure, clinical manifestation is not typical, original bacteria form complex, various affecting factors, have an adverse impact on prognosis, should implement the corresponding measures to prevent the pulmonary infection.
