Influence of bisoprolol on neuroendocrine factor levels in patients with chronic heart failure and its therapeutic effects / 心血管康复医学杂志

ABSTRACT

Objective: To explore influence of bisoprolol on neuroendocrine factor levels in patients with chronic heart failure (CHF), and its therapeutic effects.Methods: A total of 116 CHF patients, who were treated in our department from Jan 2014 to Nov 2015, were selected.According to random number table, they were randomly and equally divided into routine treatment group and bisoprolol group.Left ventricular ejection fraction (LVEF), left ventricular end-diastolic dimension (LVEDd), 6min walking distance (6MWD), serum levels of brain natriuretic peptide (BNP), endothelin (ET) and atrial natriuretic peptide (ANP) before and three months after treatment, and therapeutic effect were compared between two groups.Results: There were no significant difference in above indexes between two groups before treatment, P>0.05 all.Compared with routine treatment group after three-month treatment, there were significant rise in LVEF [(28.13±4.16)% vs.(36.02±5.14)%] and 6MWD [(245.74±44.62)m vs.(315.23±53.12)m], significant reductions in LVEDd [(62.73±10.14)mm vs.(52.82±9.47)mm], serum levels of BNP [(424.51±62.26) ng/ml vs.(324.35±50.46) ng/ml], ET [(80.14±13.25) ng/ml vs.(57.91±10.32) ng/ml] and ANP [(233.24±42.35)ng/ml vs.(164.83±31.26) ng/ml] in bisoprolol group, P<0.05 all.Compared with routine treatment group, there was significant rise in total effective rate (72.4% vs.86.2%) in bisoprolol group, P=0.04.Conclusion: Bisoprolol can significantly reduce BNP, ET and ANP levels, then delay ventricular remodeling and improve cardiac function in patients with chronic heart failure.The therapeutic effect is significant, which is worth extending.
