Abstract: Objective To observe the clinical curative effect of chronic heart failure (CHF) treated by noninvasive positive pressure ventilation ( NPPV). Methods 48 cases of CHF were randomly assigned to conventional drug treatment under oxygen (control group, n = 24) and non-invasive positive pressure ventilation ( NPPV) under the conventional therapy group (observation group, n =24). The plasma N-brain natriuretic peptide( proN-BNP) and cardiac function changes in two groups before and after treatment were observed. Results The total effective rate 92% in observation group was significantly higher than 66% in control group ( x2 =3. 7851, P ＜ 0. 05 ) ; The plasma proNBNP、respiratory rate and heart rate after treatment in two groups were lower than before treatment(t = 2.787,2.815, 2. 856,2.789,2.804,2.840,all P＜0.01) ;The plasma proN-BNPand heart rate in observation group after treatment were lower than the control group(t =2.123,2.221,all P ＜0.05). Conclusion Noninvasive positive pressure ventilation could significantly improve heart function,reduce plasma proN-BNP and enharce curative effect.
