Abstract：Objective To detect indicators of dynamic ECG（ST，ST/HR，SDNN） and preliminary evaluate the value in elderly diabetic patients before and after stent placement. Methods The indexes of ST，ST/HR and SDNN changing was selected by 12-lead dynamic electrocardiograph from young people with diabetes combined with coronary heart disease and elderly diabetes，the relativity between the indexes and coronary stenting was analysed，the ST，ST/HR and SDNN indicators in each group was compared. Results Significant difference of the indexes of ST，ST/HR，SDNN was found between the youth without stenting and older group（P <0.05），as well as the youngth with stenting（P <0.05）. There was significant difference between the young group and old group before and after coronary angiography（P <0.05）. Conclusion Significant difference was found in the indexes of ST，ST/HR，SDNN between young group and old group before and after coronary angiography as well as the stenting. The age is proved to relate with the myocardial ischemia.
