The effect observation of carvedilol and metoprolol on MMP-9 changes and left ventricular remodeling in patients with hypertension heart disease / 中国基层医药

ABSTRACT

Objective To study the curative effect of MMP-9 changes on left ventricular hypertrophy patients with hypertension heart disease by carvedilol and metoprolol.Methods 168 cases were divided into two groups.The control group(84 cases)applied metoprolol.The observation group applied carvedilol.The changes of IVST,LVPWT, LVMI and LVGI,expression of MMP-9 were observed in two groups after treatment.Results The values of IVST, LVPWT,LVMI and LVGI,expression of MMP-9 were decreased after treatment.But the decreased values of IVST [(1.72 ±0.35 )mm vs (0.36 ±0.11 )mm,t =5.75,P <0.05 ],LVPWT[(0.66 ±0.25 )mm vs (0.24 ± 0.18)mm,t =4.32,P <0.05],LVMI[(16.23 ±3.35)g/m2 vs (7.44 ±2.24)g/m2 ,t =9.86,P <0.05 ],LVGI [(0.52 ±0.12)g/m2 vs (0.40 ±0.11)g/m2 ,t =4.24,P <0.05],MMP-9[(76.23 ±20.87)vs(42.55 ±10.87),t =6.54,P <0.05]were higher in the observation group than in the control group.Conclusion The treatment of carvedilol is satisfied,can improve ventricular remodeling,decreased the expression of MMP-9,and is worthy of being recommended in left ventricular hypertrophy patients with hypertension heart disease.
