Abstract:
Objective:To explore therapeutic effect of noninvasive bilevel positive airway pressure ventilation (Bi- PAP)on aged patients with acute left heart failure (ALHF)and evaluation value of NT-proBNP for therapeutic effect in these patients.Methods:A total of 80 aged ALHF patients treated in our hospital were selected.According to random number table,they were equally divided into routine treatment group and BiPAP group (received BiPAP therapy based on routine treatment group ).NT-proBNP level,heart rate (HR),systolic blood pressure (SBP),di- astolic blood pressure (DBP),respiratory rate (RR)and arterial blood gas were compared between two groups be- fore and after treatment.Linear correlation analysis was used to evaluate the correlation among plasma NT-proBNP level and above indexes.Results:There were no significant difference in all indexes between two groups before treatment (P>0.05 all).Compared with before treatment,on 4h after treatment,there were significant reductions in levels of HR,SBP,DBP,RR and NT-proBNP,and significant rise in partial pressure of oxygen in artery (PaO2 ) in both groups (P<0.05 or<0.01),and compared with routine treatment group,there was significant rise in PaO2 [(75.13±19.93)mmHg vs.(85.88±18.47)mmHg],and significant reduction in NT-proBNP level [(3786.71± 1270.38)pg/ml vs.(2658.65±1222.08)pg/ml]in BiPAP group (P<0.05 both).Linear correlation analysis indi- cated that NT-proBNP level was significant positively correlated with HR (r=0.383),SBP (r=0.360),RR (r=0.345)and PaCO2 (r=0.413),and significant inversely correlated with PaO2 (r=-0.471),P<0.05 or<0.01. Conclusion:BiPAP ventilation therapy can improve clinical therapeutic effect in aged ALHF patients,and NT-proB- NP is help to evaluating its therapeutic effects.
