ABSTRACT
<p><b>OBJECTIVE</b>To investigate the efficacy of ACEI drugs in the treatment of hypertension patients and the effect of two levels of prevention of hypertension complicated with coronary heart disease and stroke.</p><p><b>METHDOS</b>210 cases of hypertension patients in our hospital from January 2012 to December 2015 were randomly divided into experimental group and control group, 105 cases in each group. According to the conventional symptomatic treatment, the experimental group was given lisinopril treatment, while control group was given the captopril treatment. Changes of blood pressure parameters and the level of baPWV in two groups were observed before and after treatment coronary heart disease and stroke, recurrence rate and death rate were compared in these two groups.</p><p><b>RESULTS</b>No significant difference of SBP, DBP, PP and baPWV between two groups before treatment (P>0.05). The indexes of the two groups were significantly decreased after 1 months and 3 months, and the level of patients in the experimental group was lower than that of the control group (P<0.05). The recurrence rate in the experimental group was lower than those in the control group (P<0.05).</p><p><b>CONCLUSIONS</b>ACEI drugs in the treatment of hypertension can effectively reduce the level of blood pressure, improve arterial elasticity function, reduce the recurrence rate and mortality rate of coronary heart disease and stroke. The effect of antihypertensive and two levels of prevention of hypertension complicated with coronary heart disease and stroke of lisinopril is positive.</p>
