摘　　要：目的观察老年糖尿病合并冠心病患者冠脉支架安放前后动态心电图各项指标(ST、ST/HR、SDNN)的变化,初步评价其在老年糖尿病患者安放支架术前后中的价值。方法收集青年糖尿病患者(对照组)、老年糖尿病患者(实验组),采用12导动态心电图仪观测ST、ST/HR、SDNN各项指标的变化,分析各组患者中ST、ST/HR、SDNN各指标与冠状动脉支架术的相关性。结果糖尿病合并冠心病≤60岁组ST、ST/HR、SDNN各指标安放支架前与>60岁组相比,差异有统计学意义(P<0.05);安放支架后相比有差异(P<0.05);青年组与老年组冠脉造影术前后各自相比有差异(P<0.05)。结论 ST、ST/HR、SDNN各项指标青年组、老年组各自冠脉造影术前后相比有统计学意义,冠脉造影术改善了心肌缺血。安放支架前后,≤60岁组与老年组ST、ST/HR、SDNN相比皆有统计学意义,年龄与心肌缺血有直接相关性。Objective To detect indicators of dynamic ECG（ ST, ST/HR, SDNN） and prelimi- nary evaluate the value in elderly diabetic patients before and after stent placement. Methods The inde- xes 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.
