Abstract:
Objective To observe the efficacy and prognosis of recombinant human brain natriuretic peptide ( rhBNP) and conventional treatment in acute myocardial infarction patients undergoing percutaneous coronary intervention therapy complicated by acute of left heart failure. Methods Retrospective analysis of 229 cases of hospitalized patients with acute myocardial infarction undergoing percutaneous coronary intervention therapy in 24 hours after admission, complicating with acute left ventricular failure in Shenyang Military General Hospital from June 2012 to January 2014 were enrolled and devided into: the conventional heart failure therapy group (the control group, n=122) and the rhBNP plus conventional treatment group ( the treatment group, n =107 ) , according to the patient's economic conditions and wishes. Observed improvement in heart failure symptoms before and after treatment during hospitalization and follow-up and also the 30 days and 12 months mortality. Results After 72 hrs of treatment of heart failure, both groups had decrease in heart rates, systolic blood pressure and NT-proBNP levels as compared to pre-treatment levels ( all P ﹤ 0. 05 ) . The NT-proBNP levels and heart rate of the treatment group decreased more significantly compared to the control group (both P﹤0. 05). Compared with the control group, rhBNP which to be used 72 hrs, can improve the cardiac function of AMI patients with the ratio of KillipⅡ-Ⅲ(72. 9%vs. 54. 9%, P=0. 005). There was no significant differences between two groups in in-hospital mortality and early follow-up period ( 30 days ) ( P ﹥0. 05 ) . After 12 months of follow-up, the mortality of the treatment group was lower than the control group ( 6. 5% vs. 13. 9%, P = 0. 068 ) . Through logistic regression analysis, the value of NT-proBNP and whether patients were treated with rhBNP on the basis of the routine drug were independent influencing factors for mortality of 12 months. Conclusions Additional to standard conventional therapy for acute left heart failure in patients with acute myocardial infarction undergoing PCI, rhBNP can lower the 12 months mortality and improve prognosis.
