Effect of type-A behavior pattern on intervention of benazepril in patients with essential hypertension / 中华全科医师杂志

ABSTRACT

ObjectiveTo investigate the effects of type-A behavior pattern on intervention of benasepril in patients with essential hypertension.MethodsAccording to the type-A behavior score patients with essential hypertension were divided into two groupstype-A group(n=80)and non-type-A group(n=80).Benazepfil was given to all patients for 3 months with gradual increase of dosage till the blood pressure (Bp)was controlled under 140/90 nlln Hg(1 mm Hg=0.133 kPa).The plasma levels of angiotensin II (Ang Ⅱ)was measured by radioimmunoassay and left yentrieular mass index(LVMI)was examined by ultrasonic echoeardiography(UCG)before and after treatmenL ResultsBefore benazepril treatment.plasma AngⅡ levels and LVMI in type-A group were higher than those in non-type-A group(P＜0.05),but there was no difference in Bp between two groups.Type-A behavior value were positively correlated with Ang Ⅱ and LVMI in two groups,but only Ang Ⅱ level was independent risk factor.Ang II levels were positively correlated with LVMI in two groups and that was more significantly in type-A group(P＜0.05-0.01).After treatment,Bp,plasma Ang Ⅱ and LVMI were all decreased significantly in two groups(P＜0.05-0.01)and Ang Ⅱ and LVMI were decreased more markedly in type-A group(P＜0.05).The variations of Ang Ⅱ and LVMI before and after treatment were positively correlated in two groups.but more markedly in type.A group (P＜0.05-0.01).CondusionCharacters may affect left ventricular hypertrophy in patients with essential hypertension through some stress factors and benazepril has better intervening effect on it.
