Abstract: A total of 122 patients with acute left ventricular failure from January 2011 to December 2013 at our hospital were recruited and divided randomly into control group (n =62) and observation group (n =60).Control group received conventional therapy and Bi-level positive airway pressure (Bi-PAP) was added along with conventional therapy for observation group.And 12 and 8 patients died in control and observation groups respectively within 24 h after treatment and there was no statistical difference.The BNP levels of the control group pre-treatment and at 1 h and 24 h post-treatment were (1 040 ± 315),(995 ± 245) and (570 ± 164) ng/L.The BNP levels of observation group pre-treatment and at 1 h and 24 h posttreatment were (1 080 ±209),(995 ±245) and (490 ± 138) ng/L.BNP of observation group at 1 h and 24 h post-treatment decreased significantly compared with that pre-treatment and control group (P ＜0.01).Only at 24 h post-treatment,the BNP level of control group decreased significantly compared with that pretreatment (P ＜ 0.01).
