 加拿大学者的一项研究表明,依折麦布似可逆转颈动脉粥样斑块负担。论文于2012年1月5日在线发表于《卒中》(Stroke)杂志。

  目前对依折麦布未能减少颈动脉内中膜厚度存在争议。此项研究以在血管预防门诊内接受随访的患者为受试者,并对添加依折麦布的效果进行了分析;受试者均测定颈动脉粥样斑块负担(总斑块面积)用于指导治疗。

   结果显示,231例患者具有依折麦布治疗启动之前和之后2年的总斑块面积完整资料。在依折麦布其中治疗之前和之后2年间,总胆固醇于启动治疗前(P<0.0001)、后(P<0.0001)出现显著降低;低密度脂蛋白胆固醇在启动治疗前(P<0.0001)、后(P=0.003)显著降低。甘油三酯在启动治疗前显著降低(P<0.0001),但添加依折麦布后无显著变化(P=0.48)。高密度脂蛋白胆固醇在启动治疗前无显著变化(P=0.87),但之后出现显著降低(P=0.03)。尽管添加依折麦布前低密度脂蛋白胆固醇出现降低,但个体内平均总斑块面积显著增加(6.89±39.57 mm2);添加依折麦布后尽管高密度脂蛋白出现降低,但斑块面积显著减少(−3.05±38.18 mm2)。

英文摘要:

Background and Purpose—There has been recent controversy over failure of ezetimibe to reduce carotid intima-media thickness. Much of this is based on failure to understand important differences among ultrasound phenotypes of atherosclerosis.

Methods—We analyzed the effect of adding ezetimibe to the regimen of patients being followed in vascular prevention clinics where measurement of carotid plaque burden (total plaque area) is used to guide therapy.

Results—There were complete data in 231 patients with total plaque area for 2 years before and 2 years after initiation of ezetimibe. In the 2 years before and after initiation of ezetimibe, total cholesterol decreased significantly before (P<0.0001) and after initiation of ezetimibe (P<0.0001); low-density lipoprotein cholesterol declined significantly before (P<0.0001) and after (P=0.003) initiation of ezetimibe. Triglycerides declined significantly before ezetimibe (P<0.0001) but did not change after addition of ezetimibe (P=0.48). High-density lipoprotein cholesterol did not change significantly before (P=0.87) but declined significantly after ezetimibe (P=0.03). Despite the decline in low-density lipoprotein cholesterol before addition of ezetimibe, there was a significant mean increase in within-individual total plaque area in the 2 years before addition of ezetimibe by 6.89±39.57 mm2 (SD); after addition of ezetimibe, despite the decline in high-density lipoprotein, plaque area decreased by −3.05±SD 38.18 mm2 SD (P<0.01).

Conclusions—Ezetimibe appears to regress carotid plaque burden. To assess effects of antiatherosclerotic therapies, it is important to measure plaque burden. These findings should be tested in a clinical trial.
