ABSTRACT
Objective: To evaluate the influence of recombinant human brain natriuretic peptide(rhBNP)on ventricular remodeling and ventricular systolic synchrony in patients with acute myocardial infarction (AMI) after percutaneous coronary intervention (PCI).Methods: A total of 48 patients with AMI after PCI were randomized into two groups: rhBNP Group (n=25) and Routine treatment Group (n=23).Two dimension echocardiography was used to measure the index of left ventricular end-diastolic volume (LVEDVI), the index of left ventricular end-systolic volume (LVESVI), left ventricular ejection fraction (LVEF), the index of left ventricular mass (LVMI), the movement index of infarcted regional wall (RWMI) at 1 week, 4 weeks and 24 weeks after the treatment procedure.And at 1 week and 24 weeks period, equilibrium radionuclide angiography was performed respectively to evaluate the ventricular systolic synchrony.Results: ①1 week after PCI, LVESVI in rhBNP group was decreased and LVEF was increased than that in Routine treatment group (P<0.05, respectively).4 and 24 weeks after PCI, LVEDVI, LVESVI, LVEF were significantly different in rhBNP group than those in Routine treatment group (P<0.05,respectively).24 weeks after PCI, RWMI and LVMI were significantly decreased in rhBNP group than those in Routine treatment group(P<0.05,respectively).②24 weeks after PCI, phase shift, full width at half maximum and peak phase standard deviation were significantly improved in rhBNP group than those in Routine treatment group (P<0.05, respectively).Conclusion: Intravenous injection of rhBNP could inhibit left ventricular remodeling and improve left ventricular function.
