ABSTRACT
Objective To investigate characteristics of deceleration capacity (DC) and Tp-e/QT value in different age groups of patients with diabetic autonomic neuropathy, and to analyze their influencing factors. Methods A total of 487 subjects were enrolled in this study, and divided into three groups:patients with diabetic autonomic neuropathy (DM+CAN group,n=287), normal glucose tolerance patients with diabetic autonomic neuropathy (CAN group,n=130) and healthy controls (NC group,n=150).Then the DM+CAN group were further divided into three subgroups according to age tertiles:the lowest tertile group (35.0~47.2 years old,n=91),the middle tertile group (47.3~59.6 years old,n=116)and the highest tertile group (59.7~72.0 years old,n=80).All subjects were underwent 24-hour dynamic electrocardiogram recordings.DC and Tp-e/QT values were calculated,and then the correlation between DC and Tp-e/QT with other indicators was analyzed. Results The levels of WC,SBP,BMI,FPG,HbA1c,FIns and HOMA-IR were higher in DM+CAN group than in CAN group and in NC group (P0.05).DC increased [(2.90±0.47) vs (4.22±0.41) vs (4.97±0.35) ms],and the Tp-e/QT decreased [(0.23±0.05) vs (0.18±0.03) vs (0.12±0.02)] from the highest tertile group to the lowest tertile group,(P<0.05 or P<0.01),and the pairwise comparisons were statistically significant (P<0.05 or P<0.01).Multiple stepwise regression analysis showed that age,DM duration,WC,FPG,HbA1c,complicated with hypertension and coronary heart disease (CHD) were risk factors for DC and Tp-e/QT values (P<0.05). Conclusion Together with the increased age,DC level is reduced and Tp-e/QT value increased in patients with diabetic autonomic neuropathy.Dynamic electrocardiogram should be considered in patients with advanced age,long DM duration,high level of WC,FPG,HbA1c,and complicated with hypertension and CHD,in order to prevent the occurrence of cardiovascular events effectively.
