摘要 目的 探讨256层螺旋计算机断层摄影术(256 iCT)定量参数与伴2型糖尿病(T2DM)的冠状动脉粥样硬化斑块性质、糖代谢的关系。方法 选取2019年10月至2021年10月太和县人民医院收治的100例T2DM合并冠状动脉粥样硬化斑块患者作为研究组,并选择同期83例健康者为对照组。两组均行256 iCT冠状动脉CT血管造影(CTA)、糖代谢指标检测。研究组通过冠状动脉CTA图像判断斑块性质,并对比非钙化斑块、钙化斑块、混合斑块患者的CTA定量参数(斑块CT值、左前降支与回旋支夹角、左前降支径线、左前降支截面积、回旋支径线、回旋支截面积);分析256 iCT定量参数与糖代谢的相关性。结果 研究组共发现36个非钙化斑块、62个钙化斑块、78个混合斑块。含有非钙化斑块的患者左前降支与回旋支夹角、左前降支径线、左前降支截面积、回旋支径线、回旋支截面积、斑块CT值均低于钙化斑块、混合斑块者(P<0.05),钙化斑块CT值高于混合斑块(P<0.05)。研究组回旋支径线、回旋支截面积、斑块CT值均与糖代谢呈正相关(P<0.05),左前降支与回旋支夹角、左前降支径线、左前降支截面积与糖代谢均呈负相关(P<0.05)。结论 T2DM并冠状动脉粥样硬化斑块患者256 iCT定量参数均有明显差异,且与糖代谢指标均存在相关性。
