Reversal effect of perindopril combined with amlodipine on essential hypertension with left ventricular hypertrophy and effect on plasma N-terminal B-type natriuretic peptide level
Objective:To investigate the effect of perindopril combined with amlodipine on the reversal of essen-tial hypertension with left ventricular hypertrophy and the plasma N-terminal B-type natriuretic peptide(NT-Pro BNP)level.Methods:A total of 138 patients with essential hypertension and left ventricular hypertrophy were selected as the study subjects and divided into three groups(46 cases)according to random number table method.Control group 1 was treated with amlodipine,control group 2 was treated with perindopril,observation group was treated with perindopril combined with amlodipine.The clinical efficacy,blood pressure before and after treatment,end-diastolic left ventricular diameter(LVDd),ventricular septal thickness(IvsT),left ventricular posterior wall thickness(PWT),left ventricular mass index(LVMI),NT-ProBNP,homocysteine(Hey)cardiac natriuretic peptide(ANP)levels were compared.Result:The total effective rate of the observation group was 95.65%(44/46)higher than that of the control group1[80.43%(37/46)]and control group 2[76.09%(35/46)](all P<0.05),there was no significant difference between control group 1 and control group 2(P>0.05).Before treatment,there were no significant differences in systolic blood pressure,diastolic blood pressure,I vs T,PWT,LVMI and serum NT-ProBNP,Hcy and ANP levels between the three groups(all P>0.05).After treatment,systolic blood pressure(127.87±13.66 vs 136.46±15.73 vs 135.00±15.98),diastolic blood pressure(81.07±5.58 vs 83.98±7.16 vs 85.57±7.22),LVDd(46.48±2.24 vs 48.37±3.62 vs 48.30±3.57),I vs T(10.00±1.38 vs 11.20±1.50 vs 11.24±1.55),PWT(10.52±1.35 vs 12.24±1.40 vs 12.37±1.39),LVMI(124.57±10.80 vs 145.13±10.27 vs 144.93±10.34),NT-ProBNP(64.53±15.63 vs 75.23±18.46 vs 78.15±18.54),Hcy(8.93±2.68 vs 15.48±4.66 vs 14.88±4.62)and ANP(139.95±38.64 vs 216.84±59.15 vs 213.87±59.23)were lower than those of control group 1 and control group 2(P<0.05),there was no significant difference between control group 1 and control group 2(P>0.05).Conclusion:Perindopril combined with amlodipine is effective in the treatment of essential hypertension with left ventricular hy-pertrophy,which can effectively reduce blood pressure,improve left ventricular related indexes,and reduce NT-Pro BNP level.
