目的 了解老年 2型糖尿病患者胃肠并发症与心率变异性 (HRV)之间的关系。方法 老年 2型糖尿病患者 73例 ,按有无胃肠道症状分成两组 ,分别为 37例和 36例 ,正常老年人 31例为对照组 ,进行HRV分析。结果 HRV各指标在对照组、糖尿病无消化道症状组、糖尿病伴有消化道症状组中依次降低 ,除了无症状组和对照组的SDNNindex无显著差异 (P >0 0 5 )外 ,各组间比较差异均有显著性 (P <0 0 5或P <0 0 1 )。同时糖尿病有消化道症状组较无症状组病程明显增长 (P <0 0 5 )。结论 糖尿病自主神经的损害随着病程的延长而加重 ,严重至一定程度始出现胃肠并发症的症状
Objective To understand the relationship between gastrointestinal complications and heart rate variability (HRV) in elderly type 2 diabetic patients. Methods Seventy-three elderly patients with type 2 diabetes were divided into two groups according to the presence or absence of gastrointestinal symptoms: 37 cases and 36 cases, and 31 cases of normal controls as control group. HRV analysis was performed. Results The indexes of HRV were decreased in control group, non-digestive symptoms of diabetes mellitus group, and diabetes mellitus with gastrointestinal symptoms group. Except SDNNindex of asymptomatic group and control group, there was no significant difference (P> 0.05) The difference was significant (P <0 05 or P 0 01). At the same time, there was a significant increase in the course of diabetes mellitus patients with gastrointestinal symptoms than the asymptomatic group (P <0.05). Conclusion The damage of diabetic autonomic nerve aggravates with the prolongation of the course of the disease, and the symptom of gastrointestinal complications is serious to some extent
