目的探讨趾臂指数(TBI)和踝臂指数(ABI)检查在糖耐量异常合并冠心病患者中的意义。方法对76例糖耐量异常合并冠心病患者和50例正常对照组进行冠状动脉造影和TBI、ABI检查,根据TBI、ABI检查结果和临床资料分组,进行统计学分析。结果糖耐量异常的冠心病患者Gensini评分、多支血管病变发生率高,TBI、ABI明显降低,TBI、ABI和Gensini评分呈负相关(P<0.01),TBI与ABI仅轻度相关(r=0.62,P<0.05)。结论糖耐量异常阶段即可出现TBI与ABI的降低,TBI与ABI相关性不高,联合检测可以更有效地预测和评价糖耐量异常合并冠心病患者血管病变。
Objective To investigate the significance of toe index (TBI) and ankle brachial index (ABI) in patients with impaired glucose tolerance and coronary heart disease. Methods 76 patients with abnormal glucose tolerance and coronary heart disease in 50 normal control group were examined by coronary angiography, TBI and ABI. According to the results of TBI, ABI examination and clinical data, statistical analysis was made. Results The Gensini score, the incidence of multivessel disease, TBI and ABI in patients with impaired glucose tolerance were significantly lower, TBI, ABI and Gensini scores were negatively correlated (P <0.01), and TBI was only slightly correlated with ABI (r = 0.62, P <0.05). Conclusion The incidence of TBI and ABI may be decreased during the stage of impaired glucose tolerance. The correlation between TBI and ABI is not high. Combined detection may be more effective in predicting and assessing the vascular disease in patients with impaired glucose tolerance and coronary heart disease.
