Abstract:
Objective To investigate the effects of ACEI combined with beta-blocker on cardiac function in patients with chronic heart failure (CHF)and explore its action mechanisms.Methods 60 CHF patients were enrolled in this study.The patients were randomly divided into the two groups:conventional treatment group(group A,n =30),ACEI combined with beta-blocker treatment group (group B,n =30).The LVEF,LVEDD,MMP-9,and hsCRP were recorded after treatment.The expression of MMP-9 was measured by ELISA.The level of serum hs-CRP was measured by latex enhanced immunoturbidimetric assay.Results The improvement of LVEF and LVEDD in B group [(63.21 ± 6.09) ％,(58.42 ± 5.73)mm] were better than those in A group [(41.13 ± 3.67) ％,(66.24 ± 4.24) mm] (t =7.62,6.54,P ＜ 0.01).The expressions of MMP-9 and hs-CRP in group B [(1.31 ± 0.24) ng/ml,(6.34 ± 0.58) mg/L] were significantly lower than those in A group[(2.23 ±0.39) ng/mL,(8.31 ±0.74) mg/L] (t =6.82,7.03,P ＜0.01).The total effective rate in A group was 36.7％,which was significantly lower than 73.3％ in B group(x2 =6.90,P ＜ 0.05).Conclusion The cardiac function was improved by ACEI combined with beta-blocker treatment in CHF patients.The downregulation of MMP-9 and hs-CRP may play a key role in the effective ACEI combined with beta-blocker treatment.
