Effect of recombinant human brain natriuretic peptide-assisted interventional treatment on prognosis of acute myocardial infarction patients complicated with cardiogenic shock

摘要

Objective:To analyze the effect of recombinant human brain natriuretic peptide-assisted interventional treatment on prognosis of acute myocardial infarction patients complicated with cardiogenic shock.Methods: A total of 112 cases of inpatients treated in Cardiology Department of our hospital from March 2013 to March 2015 were selected, all of whom had acute myocardial infarction within 12 hours of onset and received direct PCI treatment. They were divided into observation group and control group according to random number table, each group with 56 cases, control group received conventional interventional treatment and observation group received recombinant human brain natriuretic peptide-assisted interventional treatment. Then differences of regional myocardial deformability, myocardial enzyme spectrum indicators, brain natriuretic peptide and inflammatory factors, blood sugar and stress hormones as well as myocardial infarction prognosis-associated indexes, etc, between two groups after treatment were compared.Results:After treatment, LVEF, SRs, SRe and Sra levels of observation group were higher than those of control group, WMSI level was lower than that of control group; serum myocardial enzyme spectrum indicators CK, CK-MB, AST and LDH values were lower than those of control group; serum BNP, CRP, TNF-α and IL-6 levels were lower than those of control group; serum cortisol, growth hormone and glucagon levels were lower than those of control group, insulin level was higher than that of control group; FT3 and IGF-1 levels were higher than those of control group, sPLA2 and Hcy levels were lower than those of control group.Conclusion: Recombinant human brain natriuretic peptide-assisted interventional treatment for acute myocardial infarction patients complicated with cardiogenic shock can reduce myocardial function injury, protect normal myocardial function and optimize patients' long-term prognosis; it has active clinical significance.
