Abstract
Objective To study the therapeutic effect of recombinant human brain natriuretic peptide combined with dual-level positive airway pressure ventilation on patients with severe acute heart failure(AHF)and its impact on cardiac function,hemodynamics,and antioxidant indicators.Methods The clinical data of 107 patients with severe AHF admitted to Shanghai Pudong New Area People's Hospital from June 2020 to June 2022 were retrospectively analyzed.According to different emergency methods,they were divided into the control group(n=51)and the combination group(n=56).All patients underwent routine emergency measures such as cardiac strengthening,diuresis,and anti infection.The control group received dual-level positive airway pressure ventilation,while the combination group received dual level positive airway pressure ventilation combined with recombinant human brain natriuretic peptide treatment.The clinical effect,cardiac function indicators[left ventricular ejection fraction(LVEF),left ventricular end-systolic volume(LVESV),N-terminal pro-B-type natriuretic peptide(NT-proBNP)],he-modynamic indicators[heart rate,mean arterial pressure(MAP),arterial carbon dioxide pressure(PaCO2),and arterial oxygen pressure(PaO2)],antioxidant indicators[superoxide dismutase(SOD),catalase(CAT),glutathione peroxidase(GSH-Px)]of two groups of patients before treatment and after 72 hours of treatment were statistically analyzed,and the extubation time,and 24-hour urine output of two groups of pa-tients were recorded.Results The total clinical effective rate of the combination group was 91.07％,which was significantly higher than that of the control group(78.43％),the difference was statistically significant(P＜0.05).After 72 hours of treatment,the LVEF of patients in the combination group was(55.13±4.45)％,which was significantly higher than that of the control group[(47.96±4.75)％],LVESV and NT-proBNP were(53.61±5.45)mL and(1 848.43±209.31)ng/L in the combination group,respectively,which were significantly lower than those of the control group[69.14±5.37)mL and(2 731.35±221.57)ng/L],and the differences were statistically significant(P＜0.05).After 72 hours of treatment,the heart rate,the levels of MAP,and PaCO2 of patients in the combination group were(86.75±10.52)beats/min,(89.32±1.25)mmHg,and(40.24±3.63)mmHg,respectively,which were significantly lower than those of the control group[(98.18±8.65)times/min,(100.74±2.15)mmHg,(48.02±3.97)mmHg],the level of PaO2 was(69.37±5.07)mmHg,which was higher than that in the control group[(59.16±5.34)mmHg],and the differences were statistically significant(P＜0.05).After 72 hours of treatment,the levels of SOD,CAT,and GSH-Px of patients in the combination group were(558.16±54.35)μg/g,(281.07±45.69)μg/g and(55.34±4.14)U/L,respectively,which were significantly higher than those in the control group[(479.67±55.14)]μg/g,(229.81±45.62)μg/g,(41.05±4.91)U/L],the differences were statistically significant(P＜0.05).The extubation time for patients in the combined group was(22.31±5.81)h,which was shorter than that of the control group[(29.05±6.63)h],and the 24-hour urine output was(1 628.85± 138.92)mL,which was greater than that of the control group[(1 337.95±110.59)mL],the difference was statistically significant(P＜0.05).Conclusion The combination of recombinant human brain natriuretic peptide and dual-level positive airway pressure ventilation has sig-nificant clinical efficacy in emergency treatment of severe AHF failure.It can effectively improve the patient's cardiac function,hemodynamics,and antioxidant indicators,and is more beneficial for promoting sodium excretion and shortening extubation time.
