摘　　要：目的通过应用瑞舒伐他汀对高血压合并颈动脉斑块的患者进行干预,观察其对血脂、斑块及缺血性卒中发生率的影响。方法选取2013年5月—2015年5月就诊于邯郸市第一医院存在颈动脉斑块的高血压患者255例,随机分为对照组、瑞舒伐他汀低规剂量组(观察1组)和常规剂量组(观察2组),每组85例,均给予降压治疗及生活方式干预,对照组口服与瑞舒伐他汀相同外观的安慰剂1片,观察1组口服瑞舒伐他汀5 mg/d,观察2组口服瑞舒伐他汀10 mg/d,随访6个月。治疗前及治疗后检测血脂、血压,颈部血管超声检测颈动脉内膜-中膜厚度(iatima-media thickness,IMT)、斑块面积和Crouse斑块积分。比较治疗6个月后的脑缺血事件发生率。结果对照组治疗前、后各指标水平比较差异无统计学意义(P>0.05);治疗后观察1组、观察2组收缩压、舒张压均较治疗前下降,但差异无统计学意义(P>0.05);观察1组、观察2组治疗后TC水平较治疗前明显下降,IMT、斑块面积、Crouse积分、易损斑块率较治疗前降低,差异均有统计学意义(P<0.05),且观察2组各指标改善较观察1组明显(P<0.05)。结论瑞舒伐他汀除具有降脂作用外,还能逆转和稳定斑块,减少缺血性卒中事件的发生,且与剂量呈正相关。Objective To investigate the effect of rosuvastatin intervention on blood lipid level, carotid artery plaque and cerebral ischemic events in patients with hypertension and carotid atherosclerosis. Methods A total of 255 hypertensive patients with carotid plaques in our hospital between May,2013 and May,2015 were prospectively included, and randomly divided into control group,low dose rosuvastatin group （ observation group 1 ） and routine dose group （ observation group 2）, with 85 cases in each group. All the three group were given antihypertensive therapy and lifestyle intervention, while the control group received 1 tablet of placebo which had the same the appearance of rosuvastatin, the observe group 1 received rosuvastatin 5 mg/day, and the observe group 2 received rosuvastatin 10 mg/day. The follow up was 6 months. Before and after the treatment, the blood lipids levels, blood pressure and carotid artery intima media thickness （ IMT）, plaque area and Crouse plaque score were detected. The incidence of ischemic events after 6 months of treatment was compared. Results The indexes of the control group showed no significant difference before and after treatment （ P 〉 0.05 ） ; after treatment, the systolic blood pressure and diastolic blood pressure observation of group 1 and observation group 2 de- creased compared with prior treatment, but there was no statistical significance （ P 〉 0.05 ） ; the level of TC, LDL-C in Observation group 1, Observation group 2 was declined than before; the level of IMT, plaque area, Crouse plaque score, The rate of vulnerable plaque were elevated than before, with statistical significance（ P 〈 0.05 ）. The index improvement is obvious in Observation group 2 than Observation group. Conclusion In addition to hypolipidemic effects,Rosuvastatin can also reverse and stabilize the plaque,reduce the incidence of ischemic stroke, and is positively correlated with the dose.
