Abstract:
Objective To investigate the clinical efficacy and safety of recombinant human B-type natriuretic peptide(rhBNP)in treatreat of patients with acute myocardial infarction(AMI).Methods 80 patients with AMI were randomly divided into control and treatment group.The two groups were accepted the standard foundation treatment(ABCDE)defined by the WHO and PCI therapy.The treatment group was added the rhBNP on the basis.The rhBNP was uniformly injected by intravenous with 1.5 μg/kg in 90s,and then with 0.0075 μg · kg-1 · min-1 in 48h; To investigate the BNP and myocardiolysis maker(Troponin I,cTnI)levels in blood-serum before and after the treatment;To evaluate left cardiac functions and left ventricular remodeling by left ventricular end-diastolic volume(LVEDV),left ventricular end-systolic volume(LVESV)and left ventricular ejection fraction(LVEF);To investigate the major cardiovascular events after treatment within 30 days.Results RhBNP could significantly reduce the concentration of the BNP and cTnI in blood-serum after treating one week(all P ＜ 0.05); It could remarkably deflate LV EDV and LVESV,improve LVEF(allP ＜0.05); It could reduce the incidence of major cardiovascular events(P ＜0.05)within 30 days(P ＜ 0.05).Conclusion The rhBNP could improve left ventricular pressure-phore and volume-phore,improve ventricular remodeling,improve myocardial ischemia and reduce major cardiovascular events within 30 days.It was proved that the rhBNP could improve AMI clinical prognosis.
