摘　　要：目的:探讨增强型体外反搏(EECP)对高血压并急性脑梗死患者血管内皮功能的影响。方法:46例高血压并急性脑梗死患者分为常规治疗组(CT,n=24),常规治疗+EECP组(CT+EECP,n=22)。EECP组隔天反搏治疗2 h,总共反搏36 h,36 d。分别于体外反搏前、反搏后,采用高频超声检测肱动脉血流介导的内皮依赖血管舒张功能(FMD)方法,比较反搏组与非反搏组治疗前后FMD的变化。同时检测血浆内皮素(ET)、一氧化氮(NO)。结果:CT组、CT+EECP组治疗后FMD明显升高,分别为5.15%±1.01%(P<0.05),7.87%±0.86%(P<0.01),两组比较差异有统计学意义(P<0.05),CT+EECP组NMD也得到改善(P<0.05),而常规治疗组NMD无显著改善;两组患者经治疗后ET均明显下降(78.55±12.63,60.21±10.58,P<0.05和P<0.01)、NO均明显上升(67.88±16.56,82.21±20.12,P<0.05和P<0.01);EECP组下降更为显著,下降幅度与常规治疗组比较,差异有统计学意义(P<0.05)。结论:增强型体外反搏可改善急性脑梗死患者血管内皮功能。Objective：To explore the effect of Enhanced External Counterpulsation（EECP） on vascular endothelial function in acute cerebral infarction Patients.Methods：Forty-six acute cerebral infarction patients were randomly divided into 2 groups：the conventional therapeutics group（CT,n=24）,and the ＂conventional therapeutics＋EECP＂ group（CT＋EECP,n=22）.EECP was performed on CT＋EECP group,2 hours every other day lasting for 36 days.Endothelial dependent flow-mediated vasodilation（FMD） of the right brachial artery was assessed by day 0（prior to EECP） and day 36,respectively,immediately after EECP treatment.Plasma ET and Nitric oxide（NO） were measured at the same time points in all Patients.Results：In CT＋EECP group,FMD was improved significantly [（7.87%±0.86%）,P 0.01]after treatment,comparing to the CT group [（5.15%±1.01%）,P0.05].In CT＋EECP group NMD was improved significantly too（P0.05）.Level of Endothelin（ET） was significantly decreased in CT＋EECP group（60.21±10.58,P0.01）,comparing to the CT group [（78.55±12.63） mg/L,P0.05] after 36-day treatment.However,Level of Nitric oxide（NO） was significantly improved in CT＋EECP group（82.21±20.21,P0.01）,comparing to the CT group [（67.88±16.56） mg/L,P0.05] after treatment.Conclusions：EECP could improve endothelial dysfunction of acute cerebral infarction patients.
