Role of N-terminal pro-brain natriuretic peptide in differentiating heart failure in the patients with acute dyspnea / 中国实用内科杂志

ABSTRACT

Objective To study the differential diagnostic value of serum N-terminal pro-brain natriuretic peptide(NT-proBNP)in the patients with acute dyspnea.Methods Sixty-two patients in Medical Department of the People's Hospital of Huangpu were included in this study.Patients were divided into two groupsdyspneic patients with heart failure and without heart failure.Thirty healthy cases were selected as the control group.The concentration of serum NT-proBNP,LVEF was determined in all cases.We analyzed the relationship between NT-proBNP and LVEF.Furthermore we analyzed the relationship between NT-proBNP and the NYHA Class.Results LVEF of the control group,dyspneic patients without heart failure and with heart failure was(60.82?5.53)%,(55.92?5.62)% and(40.25?4.85)%.It had significant difference in the control group,dyspneic patients without heart failure and with heart failure(P
