目的探讨 QTc值对糖尿病心脏微血管病变的诊断和对死亡预测的价值。方法将糖尿病微血管病变患者 (n=38)的 QTc均值42 8.2 90 3± 33.95 41)毫秒与无糖尿病微血管病变患者 (n=46 )的 QTc均值 (40 5 .5 2 38± 30 .32 12 )毫秒进行比较 ,并将糖尿病微血管病变组 QTc均值与糖尿病死亡病例 12例 QTc均值 434.0 0 0 0± 34.5 86 1)毫秒比较。结果两组之间存在高度显著性差异 (P<0 .0 1)。后者两组之间无显著性差异 (P>0 .0 5 )。结论 QTc延长对糖尿病心脏微血管病变的诊断有一定参考价值
Objective To investigate the value of QTc in the diagnosis of diabetic microangiopathy and prediction of death. Methods The QTc mean (40.5238 ± 30.3212) QTc of patients with diabetic microangiopathy (n = 38) was 42 8.2 90 3 ± 33.95 41 msec and that of non-diabetic microangiopathy patients (n = 46) The mean QTc in diabetic microangiopathy group was compared with the QTc mean of 12 cases of death from diabetes mellitus 434.0 0 ± 34.5 86 1) milliseconds. Results There was a highly significant difference between the two groups (P <0.01). There was no significant difference between the latter two groups (P> 0.05). Conclusions QTc prolongation has some reference value for the diagnosis of diabetic microangiopathy
