Abstract
Objective To investigate the clinical value of serum NT-proBNP level in the diagnosis of acute dyspnea in elderly patients.Methods Selected 2014 March 2015 August Jiexi County People's hospital emergency department of 90 patients with acute dyspnea patients as the research object,including 45 cases of cardiogenic dyspnea, pulmonary dyspnea in 45 cases,compared two groups of patients with serum NT-proBNP level and analysis the correlation between NT-proBNP levels and left ventricular ejection fraction.Results Serum NT-proBNP level in patients in cardiac dyspnea group was significantly higher than that of pulmonary respiratory difficulty group,LVEF was significantly lower than that of pulmonary respiratory difficulties,differences were statisticaly significant(P<0.05); cardiac dyspnea serum NT-proBNP levels in patients with LVEF was negative correlation(r=-0.768,P<0.01). Conclusion NT-proBNP can serve as an important indicator to identify cardiac dyspnea and pulmonary dyspnea,to a certain extent,can determine the degree of heart failure,and its detection method is simple and fast.关键词
