摘要
目的探讨高脂血症对肱动脉内径达峰时间的影响。方法选取到我院就诊、未曾治疗的40例高脂血症患者作为研究对象(高脂血症组),另选对照组30名,应用在血管回声跟踪技术(eTRACKING)基础上实现的血流介导血管舒张(FMD)检测技术及FMD专用检测装置测量肱动脉内径达峰时间,并进行分析。结果高脂血症组肱动脉内径达峰时间为(70.70±6.99)s,对照组为(60.25±5.38)s,差异有统计学意义(P<0.001)。结论高脂血症患者动脉内膜出现异常改变之前已出现内皮功能损伤,运用这种新的FMD检测技术测量肱动脉内径达峰时间,可作为判断早期血管功能受损的新指标。
Objective To explore the impact of Hyperlipoidemia on time to peak of the brachial artery diameter.Methods Forty patients with untreated Hyperlipoidemia（Hyperlipoidemia group） and 30 normal subjects（control group） were enrolled in this research.Flow mediated dilation（FMD） detection based on the echo-tracking technology（eTRACKING） and the FMD-specific device were applied to measure time to peak of the brachial artery diameter.Data were statistically analyzed.Results Time to peak of the brachial artery in Hyperlipoidemia group was（70.70±6.99）s and that of control group was（60.25±5.38）s.There was significant difference between the two groups（P0.001）.Conclusion Endothelial damage may occur before its dysfunction.Time to peak of the brachial artery diameter measured by the new FMD detection technology can be used as a useful indicator for early endothelial damage.
