ABSTRACT
Objective To explore the effect of pravastatin on carotid atherosclerosis in the patients with type 2 diabetes mellitus (T2DM) complicating hypertension.Methods One hundred and six patients.with T2DM complicating hypertension treated in this hospital from April 2015 to April 2016 were selected and divided into the conventional treatment group (n=52) and pravastatin group (n=54).The patients of conventional treatment group were given the conventional therapy of diet control,reducing blood glucose,controlling hypertension,symptomatic and support treatment,while on the basis of conventional therapy the patients of pravastatin group were added with pravastatin.The carotid intima-medial thickness (IMT),detection rate of carotid atherosclerotic plaque and carotid plaque score were measured by ultrasound before and after the treatment in all cases.Meanwhile the levels of serum lipid and hyper sensitive C reactive protein (hs-CRP) were determined.Results The above indicators in the conventional treatment group had no statistically significant difference between before and after treatment (P＞0.05),but the IMT value,detection rate of carotid atherosclerotic plaque and carotid plaque score after treatment in the pravastatin group were decreased compared with before treatment,the levels of serum total cholesterol (TC),triacylglycerol (TG),low density lipoprotein cholesterol (LDL-C) and hs-CRP were also significantly reduced compared with before treatment,the differences were statistically significant (P＜0.05),moreover the above indicators after treatment in the pravastatin group were remarkably lower than those in the conventional treatment group (P＜0.05).There was no statistically significant difference in the incidence rate of adverse reactions between the two groups (P＞0.05).Conclusion Pravastatin can effectively and safely improve the carotid atherosclerosis degree in the patients with T2DM complicating hypertension.
