摘要
目的 旨在通过高脂餐试验 ,研究调脂治疗对冠心病患者餐后血管内皮功能变化的影响。方法  5 0例来源于我院心血管内科门诊和住院的冠心病患者。经饮食宣教 4周后 ,开始高脂餐试验和采用高分辨血管外超声法检测肱动脉血流介导的内皮依赖性血管舒张功能 (FMD)。随后将受试者随机分为常规治疗组和血脂康组。治疗 6周后重复上述检查。结果 治疗前两组高脂餐后 4h的FMD明显受损 (P <0 0 5 ) ,餐后血清甘油三酯 (TG)浓度明显升高 (P <0 0 5 ) ,两组间餐后甘油三酯曲线下面积 (TG AUC)差异无显著性。 6周后血脂康组餐前和餐后FMD有明显改善 (P <0 0 5 ) ,且空腹FMD和餐后FMD差异无显著性 ,而常规治疗组空腹FMD和餐后FMD较治疗前无明显变化 ,餐后FMD仍显著受损 (P <0 0 5 )。相关分析显示餐后TG AUC与餐后 4h内皮依赖性血管舒张功能下降值正相关 (r=0 32 2 ,P <0 0 5 )。治疗后TG AUC的变化与空腹和餐后FMD的变化显著相关 (P <0 0 1)。结论 高脂餐后冠心病患者血管内皮功能受损 ,可能与餐后血脂紊乱有关。提示血脂康调脂治疗有效改善冠心病患者空腹和高脂餐后血管内皮功能。
