Abstract

The prevalence of QT prolongation in a large random sample of Type 1 diabetic patients in Piemonte, Italy and its association with autonomic neuropathy were assessed. Three hundred and seventy-nine Type 1 diabetic patients (age 15-59) with (94, DAN+) and without (280, DAN-) autonomic neuropathy and 118 non-diabetic control subjects participated in the study. QT interval was measured on an ECG recorded at rest and QTc calculated according to Bazett's formula. QTc was greater than 0.440 s in 7.6% (95% CI 2.9-12.3) of control subjects, 25.6% (21.0-30.0) of diabetic patients, 30.8% (21.5-40.1) of DAN+, 23.9% (18.9-28.9) of DAN-. QTc was greater than 0.460 s (mean + 2SD of QTc in control subjects) in 11.7% (8.5-14.9) of diabetic patients, 18.1% (10.3-25.9) of DAN+, 9.6% (6.2-13.0) of DAN-. QT was above the 95% upper limit for the control subjects in the plot of measured QT against RR interval in 21.4% (17.3-25.5) of diabetic patients, 26.6% (17.7-35.5) of DAN+, 19.3% (14.7-23.9) of DAN-. No correlation was found between QT interval and age or disease duration. The prevalence of QT prolongation was higher in diabetic patients than in control subjects and in DAN+ than in DAN-.

摘要

评估了意大利皮埃蒙特地区一大群1型糖尿病患者QT间期延长的患病率及其与自主神经病变的关联。379例15至59岁的1型糖尿病患者参与了研究,其中伴有自主神经病变的患者94例(DAN +),不伴有自主神经病变的患者280例(DAN -),另有118名非糖尿病对照者。静息心电图测量QT间期,并根据Bazett公式计算QTc。对照者中QTc大于0.440秒的比例为7.6%(95%CI 2.9 - 12.3),糖尿病患者为25.6%(21.0 - 30.0),DAN +患者为30.8%(21.5 - 40.1),DAN -患者为23.9%(18.9 - 28.9)。糖尿病患者中QTc大于0.460秒(对照者QTc均值 + 2SD)的比例为11.7%(8.5 - 14.9),DAN +患者为18.1%(10.3 - 25.9),DAN -患者为9.6%(6.2 - 13.0)。在测量的QT与RR间期的关系图中,糖尿病患者中QT高于对照者95%上限的比例为21.4%(17.3 - 25.5),DAN +患者为26.6%(17.7 - 35.5),DAN -患者为19.3%(14.7 - 23.9)。未发现QT间期与年龄或病程之间存在相关性。糖尿病患者中QT间期延长的患病率高于对照者,DAN +患者高于DAN -患者。
