无创动脉检测在2型糖尿病合并下肢血管病变的应用

目的分析无创动脉检测技术在2型糖尿病合并下肢血管病变的应用价值。方法选择2007年1月～2008年9月治疗的2型糖尿病患者56例为糖尿病组，选择同期健康体检人员60例为对照组，检测脉搏波传导速度（PWV）、踝臂指数（ABI）及脉压指数，对糖尿病组下肢动脉斑块情况进行统计。结果糖尿病组PWV（19．08±5．16）m／s]高于对照组（15．40±3．36）m／s]，糖尿病组ABI（1．06±0．11）低于对照组（1．14±0．08），糖尿病组脉压指数（0．42±0．04）高于对照组（0．34±0．05），差异均有高度统计学意义（均P〈0．01）。其中7例患者ABI〈0．9，进一步行下肢动脉彩超发现5例患者有动脉斑块形成。结论无创动脉检测技术对2型糖尿病合并下肢血管病变患者有较好的敏感性，能早期发现动脉硬化和可能存在动脉阻塞患者，为临床早期干预治疗提供较好的应用价值。

Application of non-invasive atherosclerosis detection technology in type 2 diabetic patients with lower extremity vascular disease

Objective To analyze the application value of non-invasive atherosclerosis detection technology in type 2 diabetic patients with lower extremity vascular disease. Methods 56 patients with type 2 diabetes from January 2007 to September 2008 were selected as diabetes mellitus group, 60 cases of healthy personnel were chosen as control group; pulse wave speed （PWV）, ankle-brachial index （ABI） and pulse pressure index were detected, lower limb artery plaque situation of diabetes mellitus group was analyzed. Results PWV in diabetes mellitus group （19.08±5.16） m/s] was higher than that in control group （15.40±3.36） m/s], ABI in diabetes mellitus group （1.06±0.11） was lower than that in control group （1.14±0.08）, pulse pressure index in diabetes mellitus group （0.42±0.04） was higher than that in control group （0.34±0.05）, the differences were statistically significant （P 〈 0.01）. 5 cases with artery plaque formation were found by color Doppler ultrasound in 7 cases whose ABI was less than 0.9. Conclusion Non-invasive atheroscle- rosis detection technology has better sensitivity to the early detection of type 2 diabetes patients with atherosclerosis, and can find patients with blocked arteries earlier, provides better value for early clinical intervention.
