Risk Factors of Vulnerable Coronary Plaque Formation in Type 2 Diabetes

  • 摘要: 目的:探讨2型糖尿病(T2DM)冠状动脉易损斑块的相关因素,为临床预测和管理T2DM患者冠脉易损斑块提供重要依据。方法:回顾性分析150例T2DM患者的相关临床指标及冠脉斑块的CT血管造影(CTA)数据,并以是否存在易损斑块分组,探讨T2DM患者冠脉易损斑块形成的独立危险因素,并对相关因素进行ROC曲线分析其诊断效能。结果:甘油三脂(TG)为T2DM患者出现易损斑块的独立危险因素(OR=1.49,95% CI 1.02~2.18);范围内时间(TIR)(OR=0.95,95% CI 0.92~0.97)和高密度脂蛋白(HDL)(OR=0.32,95% CI 0.13~0.78)为独立保护因素。TIR、TG、HDL的曲线下面积(AUC)分别是:0.71、0.69、0.65。联合预测的AUC为0.76,95% CI:0.68~0.83,灵敏度75%,特异度70%。结论:T2DM患者TIR及HDL减低、TG升高时,临床应警惕合并冠脉易损斑块的可能。
