【摘要】 目的分析心力衰竭产妇继发肺部感染与心功能变化的关系,为肺部感染临床防治提供参考。方法对42例心力衰竭继发肺部感染产妇作为研究组,并将38例单纯心力衰竭产妇作为对照组,两组均检测并比较血管加压素、血浆脑钠肽水平。结果研究组血管加压素水平为(235.4±50.7)pg/300μl,对照组为(197.8±33.2)pg/300μl;研究组血浆脑钠肽水平为(324.6±22.3)ng/L,对照组为(96.5±7.8)ng/L;研究组血管加压素及血浆脑钠肽水平均高于对照组(P<0.01);研究组患者随着心功能下降其血浆脑钠肽水平及血管加压素水平不断升高(P<0.01)。结论心力衰竭产妇继发肺部感染可通过影响产妇机体血管加压素、血浆脑钠肽水平而影响心功能,加重心功能不全,临床对于心力衰竭产妇应积极控制肺部感染。更多还原

【Abstract】 OBJECTIVE To analyze the relationship between the change of cardiac function of the maternal with heart failure and the pulmonary infections so as to provide reference for the clinical prevention of pulmonary infections.METHODS A total of 42 maternal with heart failure complicated with lung infection were assigned as the study group,while 38 maternal with heart failure were set as the control group;the vasopressin and plasma brain natriuretic peptide levels of the two groups were detected and compared.RESULTS The vasopressin level of the study group was(235.4±50.7)pg/300μl,the control group(197.8±33.2)pg/300μl;the plasma brain natriuretic peptide level of the study group was(324.6±22.3)ng/l,the control group was(96.5±7.8)ng/l;the vasopressin level and the plasma brain natriuretic peptide level of the study group were higher than that of the control group(P<0.01);with the decreased of cardiac function,the plasma brain natriuretic peptide level and vascular vasopressin level elevated constantly(P<0.01).CONCLUSION The cardiac function of the maternal with heart failure can be affected through the impact of pulmonary infections on the levels of maternal body vascular vasopressin and the plasma brain natriuretic peptide,aggravating the ventricular dysfunction,therefore,the pulmonary infections in the heart failure maternal should be actively controlled.更多还原
