阿托伐他汀对老年高脂血症患者颈动脉斑块的影响

目的 探讨阿托伐他汀对老年高脂血症患者颈动脉斑块的影响.方法 155例伴有颈动脉斑块的老年高脂血症患者应用阿托伐他汀20 mg/d治疗.治疗前、治疗后6个月检测血脂水平,经彩色多普勒超声检测颈动脉内膜中层厚度(IMT)、斑块最大厚度(Tmax)及最大面积(Smax).结果 治疗后患者TC、TG、LDL-C较治疗前明显下降(4.07±0.52)mmol/L比(5.83±0.76)mmol/L,(1.65±0.24)mmol/L比(2.18±0.37)mmol/L,(2.98±0.31)mmol/L比(3.75±0.49)mmol/L,均P＜0.05)],HDL-C较治疗前明显升高(1.27±0.19)mmol/L(0.94±0.15)mmol/L,P＜0.05];颈动脉IMT、Tmax、Smax较治疗前明显下降(1.15±0.13)mm比(1.41±0.19)mm,(2.01±0.19)mm比(2.29±0.24)mm,(13.61±2.87)mm2比(16.75±3.06)mm2,均P＜0.05].结论 阿托伐他汀具有延缓动脉粥样硬化进程及稳定斑块的作用.

Abstract：

Objective To study the effects of atorvastatin on atherosclerotic plaques in the elderly patients with hyperlipoidemia. Methods Atorvastatin 20 mg/d was administered in 55 cases of atherosclerotic plaques in elderly patients with hyperlipoidemia. The levels of blood fat and carotid intima-media thickness (IMT) , maximal plaque thickness (Tmax) and maximum size (Smax) were observed by Color Doppler ultrasound before and after 6 months treatment. Results The levels of TC, TG, LDL-C in patients after treatment were significant lower than those before treatment (4.07±0.52) mmol/L vs (5. 83 ±0. 76)mmol/L, (1. 65 ±0.24)mmol/L vs (2. 18 ± 0.37)mmol/L, (2.98 ±0. 31)mmol/L vs (3.75 ±0.49)mmol/L,P＜0. 05] , HDL-C was significant higher than that before treatment (1.27 ±0.19) mmol/L vs(0.94 ±0.15) mmol/L,P＜0.05]. The carotid IMT, Tmax, Smax were significantly lower than those before treatment (1. 15 ±0.13) mm vs (1.41±0.19) mm, (2.01 ± 0.19)mm vs (2.29 ±0.24)mm,(13.61 ±2.87)mm2 vs (16.75 ±3.06)mm2,P＜0.05]. Conclusion Atorvastatin can delay the process of atherosclerosis and stabilize plaques.
