Abstract:

Objective To investigate the therapeutic effects of varying treatment durations of recombinant human brain natriuretic peptide (rhBNP) on heart failure following percutaneous coronary intervention (PCI) in patients with acute ST-segment elevation myocardial infarction (STEMI). Methods A total of 196 STEMI patients with heart failure (HF) following emergency percutaneous coronary intervention (PCI) were enrolled and randomly assigned to one of four groups: control group (n = 53), short-course rhBNP group (n = 47), medium-course rhBNP group (n = 50), and long-course rhBNP group (n = 46). The rates of cardiovascular mortality and HF-related rehospitalization were evaluated at 30 days and 6 months post-treatment. Serum levels of N-terminal pro-B-type natriuretic peptide (NT-proBNP), matrix metalloproteinase-9 (MMP-9), tissue inhibitor of matrix metalloproteinase-1 (TIMP-1), left ventricular end-diastolic diameter (LVEDD), and left ventricular ejection fraction (LVEF) were measured at 24 hours, 3 days, 1 week, 30 days, and 6 months after HF treatment initiation. Results Compared with the control group, both the short- and medium-term rhBNP groups showed a significant reduction in cardiovascular mortality and HF-related rehospitalization rates in the long-term rhBNP group at 30 days and 6 months (P < 0.05). Additionally, the medium-term rhBNP group exhibited lower HF-related rehospitalization rates than both the control and short-term rhBNP groups (P < 0.05). Serum levels of NT-proBNP, MMP-9, and LVEDD significantly decreased in the short-term rhBNP group within 24 hours compared to the control group (P < 0.05), while TIMP and LVEF levels increased (P < 0.05). In comparison with the short-term rhBNP group, the medium-term rhBNP group demonstrated sustained reductions in NT-proBNP, MMP-9, and LVEDD levels at 72 hours, 1 week, 30 days, and 6 months (P < 0.05), accompanied by increases in TIMP and LVEF (P < 0.05). Furthermore, the long-term rhBNP group showed greater improvements than the medium-term group, with significantly lower NT-proBNP, MMP-9, and LVEDD levels and higher TIMP and LVEF values at 1 week, 30 days, and 6 months (P < 0.05). In terms of the adverse reactions, the incidence of hypotension in the control group, short course rhBNP group, medium course rhBNP group and long course rhBNP group increased successively (P < 0.05). Conclusion The clinical efficacy of rhBNP in STEMI patients with HF following PCI gradually improved as the treatment duration increased, but the incidence of hypotension also rose accordingly.
