Abstract:
Objective To investigate the changes in serum matrix metalloproteinase(MMP)-2 and MMP-9 and their relationship with serum B-type brain natriuretic peptide(BNP)in patients with chronic heart failure.Methods MMP-2,MMP-9 and serum BNP levels were measured in 184 patients with chronic heart failure and 61 healthy controls.The relationship between changes in MMP-2 and-9 and serum BNP was analyzed.Results Chronic heart failure was categorized into grade Ⅱ,Ⅲ and Ⅳ according to NYHA.In grade Ⅱ,Ⅲ and Ⅳ and the control group,the levels of MMP-2 were(309.1±60.1)nmol/L,(422.6±89.6)nmol/L,(694.8±126.2)nmol/L and(217.2±26.3)nmol/L respectively,and the levels of MMP-9 were (321.2±63.2)nmol/L,(454.4±96.3)nmol/L,(634.1±51.2)nmol/L and(210.8±23.6)nmol/L respectively.The levels of MMP-2 and MMP-9 were significantly higher in chronic heart failure subgroups than in the control group(F=3.65,12.52;P=0.000,0.000).According to the pairwise comparison among the chronic heart failure subgroups,the levels of serum MMP-2 and MMP-9 were significantly higher in NYHA Ⅳ grade than in NYHA Ⅲ grade,and higher in NYHA Ⅲ grade than in NYHA Ⅱ grade(all P<0.05).In patients with chronic heart failure groups,MMP-2 was positively correlated with serum BNP(r=0.866,P=0.000),and with MMP-9(r=0.516,P=0.001).Conclusions MMP-2 and MMP-9 levels might be closely correlated with chronic heart failure and show an upward trend with the progression of chronic heart failure.The levels of MMP-2 and MMP-9 are associated with BNP,which indicates that clinical monitoring of the serum level changes can provide a certain reference for diagnosis,treatment and prognosis in patients with chronic heart failure.
