血管内超声对合并糖尿病心绞痛患者罪犯病变斑块特点的研究

【目的】用血管内超声（intravascular ultrasound，1VUS）对有无糖尿病（diabetes mellims，DM）冠心病患者的冠状动脉影像特征进行分析。【方法】入选经冠状动脉造影确诊为冠心病的患者141例，按是否合并DM分为两组，DM组23例，非DM组118例。用IVUS对两组的141处缺血相关病变进行分析。【结果】共分析141处病变，DM组最小管腔横截面积（LA）明显〈非DM组，而最小外弹力膜横截面积（EEM）、斑块面积（PA）和斑块负荷（PB）明显〉非DM组（P〈O．05）。DM组参考节段管腔横截面积（RLA）明显〈非DM组，而参考节段斑块面积（RPA）、斑块负荷（RPB）则明显〉后组（P〈0．001）。两组病变的重构类型、斑块性质、偏心性无显著的统计学差异。【结论】合并DM冠心病的缺血相关病变和参考节段的斑块负荷明显〉无DM者，血管动脉粥样硬化程度非常严重，并且非常弥漫。两组斑块的稳定性无显著性差异。

Analysis of culprit plaque in angina pectoris patients accompanied with diabetes using in-travascular ultrasound imaging

Objective] To observe the features of the cttlprit vessel in patients with accompanied angina pectoris patients with diabetes by Intravasctdar ultrasound. Methods] 141 cases that were proved AP by IVUS were selected and divided into two groups according to with or without diabetes. DM group 23 cases; without DM group 118.IVUS were applied in all patients with CAD. Results] 141lesions were analyzed, the LA of DM was smaller than without DM, the EEM, PA, PB were larger than without DM. （ P 〈0.05）; the RLA of section with DM was smaller than without DM, the RPA, RPB of section with DM were larger than without DM, （ P 〈 0.001） .There were no significant differences in plaque character and remodeling index type between two groups. Conclusions] The PB in lesion segment and reference segment were larger in patients with AP accompanied with diabetes. The lesion was very hard and diffuse. There were no significant differences in plaque character.
