The effect and safety of amlodipine besylate combined with benazepril in treatment of old patients with primary hypertension and left ventricular hypertrophy

Abstract

Objective To observe the effect of amlodipine besylate combined with benazepril in treatment of old patients with primary hypertension and left ventricular hypertrophy,and analyze the safety.Methods One hundred and eight old patients with primary hypertension and left ventricular hypertrophy were divided into observation group (54 cases) and control group (54 cases) by random digits table.The patients in observation group were treated with amlodipine besylate combined with benazepril and the patients in control group were only treated with amlodipine besylate.The levels of blood pressure,interventricular septal thickness (IVST),left ventricular posterior wall (LVPW),left ventricular end-diastolic dimension (LVEDD) and left ventficular mass index (LVMI) before and after treatment for 6 months were measured and compared between two groups.The adverse effects after treatment were compared too.Results After treatment,the levels of 24hSBP,24hDBP,IVST,LVPW,LVEDD and LVMI were significantly decreased in both groups (P ＜ 0.05).Moreover,the levels of 24hSBP,24hDBP,IVST,LVPW,LVEDD and LVMI after treatment in observation group were significantly lower than those in control group(P ＜ 0.05).There was 1 case ( 1.9％ ) of dry cough,2 cases (3.7％) of mild ankle edema in observation group,while only 2 cases (3.7％) of mild ankle edema in control group.There was no significant difference in adverse effects between two groups (P ＞ 0.05).Conclusions Compared with amlodipine besylate single treatment,amlodipine besylate combined with benazepril in treatment of old patients with primary hypertension and left ventricular hypertrophy can more effectively control blood pressure and reverse left ventricular hypertrophy.The adverse effects are not increased,which can be applied in clinic.
