Meta-Analysis of the Effects of Recombinant Human Brain Natriuretic Peptides on Left Ventricular Remodeling in Patients with Acute Myocardial Infarction

Abstract

Objective. Systematic evaluation of the efficacy of natriuretic recombination in human brain on disease myocardial infarction, left ventricular heart failure, and the efficacy and safety of long-term left ventricular remodeling. Methods. Computerized search of CNKI, Wanfang database, Wipro Chinese Technology Publications (VIP) numerical database, Chinese Biomedical Literature Database (CBM), Medline Cochrane Library, clinical Trail.Gov clinical collection, and other documents. Randomized controlled trials (RCT) of recombinant human brain natriuretic peptide in the treatment of acute myocardial infarction from inception to December 2021 were searched. Based on the Jadad scale, inclusion-exclusion data for diseases were collected and elaborated by meta by RevMan 5.3 simulation software. In a total of 23 randomized controlled trials, 2 024 cases were used as the basic data, the control group was routinely treated for 1 012 cases, and 1 012 cases in the experimental group were also treated with natriuretic peptide in the recombinant human brain on the previous basis. Results. In terms of overall efficacy, the experimental group was better than the control group, statistically significant ( $\text{OR}=4.30$ , 95% CI (3.26, 5.67), $P<0.00001$ ), left ventricular ejection fraction in the experimental group than the control group ( $\text{OR}=1.58$ , 95% CI (1.27, 1.90), $P<0.00001$ ). In terms of a myocardial strain in the left ventricle, the experimental group was superior to the control group. The difference was significant ( $\text{OR}=-0.91$ , 95% CI (-1.50, -0.33), $P=0.002$ ). In terms of the cardiac output volume, the experimental group was superior to the control group ( $\text{OR}=1.24$ , 95% CI (0.55, 1.94), $P=0.0005$ ). Regarding brain natriuretic peptide precursors, the experimental group was superior to the control group ( $\text{OR}=-4.37$ , 95% CI (-6.21, -3.25), $P<0.00001$ ). In terms of the heart rate, the experimental group was superior to the control group. Measurement of differential significance is as follows: $\text{OR}=-13.70$ , 95% CI (-14.95, -12.46), $P<0.00001$ . In terms of contraction, the experimental group was superior to the comparison group ( $\text{OR}=-12.38$ , 95% CI (-17.98, -6.79), $P<0.00001$ ). The experimental group outperformed the control group ( $\text{OR}=-7.42$ , 95% CI (-8.53, -6.30), $P<0.00001$ ). In terms of bad influence, the measurement is as follows: $\text{OR}=0.95$ , 95% CI (0.29, 3.16), $P=0.94$ . Conclusion. In patients with acute myocardial infarction and left ventricular remodeling, if treated with a heavy treatment of the group of cerebral natriuretic peptide mode, it can increase clinical treatment, improve the cardiac effect, inhibit ventricular remodeling, improve blood pressure and heart rhythm, and have greater clinical treatment and safety.
