To investigate the effect of simvastatin on blood lipid incidence in patients with hypertension and normal blood pressure control and cardiovascular events. Methods:180 cases of patients with hypertension, were randomly divided into routine treatment group (90 cases) and simvastatin group (90 cases), al the patients were treated with calcium antagonist combined with angiotensin converting enzyme inhibitor (ACEI) of antihypertensive treatment, simvastatin group were treated with simvastatin capsules of 20mg/ D. And 1 years of folow-up, two groups were observed in patients with blood pressure control and cardiovascular events (heart function of angina, myocardial infarction, no difference in the incidence of total).Results:after 1 years of treatment, simvastatin group blood pressure and cardiovascular events were compared with routine treatment group decreased significantly (P <0.05)conclusion:blood pressure control with simvastatin can beter, and reduce the incidence of cardiovascular events in patients with hypertension.
