摘　　要：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.
