目的探讨2型糖尿病患者无症状心肌缺血(SMI)发作与其心率变异性之间的临床关系。方法：选取2009年1月至2012年1月间于我院行运动负荷心肌灌注显像检查的2型糖尿病患者76例,所有患者在1个月内均行动脉心电图监测,38例诊断SMI患者为观察组,38例无心肌缺血发作患者为对照组。结果：观察组SDNN、SDANN、PNN50、PMSSD、SDNNI均明显低于对照组,以上组间差异均具有统计学意义(P<0.05)；而其24h的Mean HR明显高于对照组,组间差异在统计学上有意义(P<0.05)。结论：心率变异性减低与2型糖尿病SMI发生相关性明显,可作为2型糖尿病患者SMI筛查的一种安全、有效、无创、重复性好的观察指标。

Objective:To investigate the type 2 diabetes of the relationship between the clinical on silent myocardial ischemia attack (SMI) and heart rate variability. Methods:Stressed myocardial perfusion imaging examination of 76 patients with type 2 diabetes in our hospital from January 2009 to January 2012, all patients were performed arterial electrocardiogram (ecg) monitoring, within 1 month, the Observation group of 38 patients with SMI, the control group of 38 cases of patients without myocardial ischemia attack.Results:The observation group SDNN,SDANN,PNN50,PMSSD,SDNNI were significantly lower than control group, the difference between above group were statistically significant (P<0.05);mean HR of 24 h was obviously higher than that of control group, the difference between groups was statistically significant (P<0.05). Conclusion:The correlation was obvious between heart rate variability reduction and SMI type 2 diabetes mellitus, It can be as an observed index was about SMI in type 2 diabetes patients,It is safe, effective, non-invasive and reproducible.
