Differences in Prevalence and Incidence of Electrocardiogram Abnormalities and Cardiovascular Autonomic Neuropathy Among Randomized Glucose-Lowering Treatments in Early Type 2 Diabetes: The Glycemia Reduction Approaches in Diabetes (GRADE) Cohort.

ABSTRACT:

Objective

To describe the prevalence and incidence of electrocardiogram (ECG) abnormalities and ECG-derived cardiovascular autonomic neuropathy (CAN) in the GRADE cohort of adults with type 2 diabetes (T2D) <10 years.

Research design and methods

Individuals with T2D taking metformin alone were randomly assigned to add insulin glargine, glimepiride, liraglutide, or sitagliptin. Resting ECGs were completed at the baseline, 2-year, and 4-year study visits and analyzed for minor and major abnormalities and CAN assessed with heart rate variability (HRV) in 4,769 participants. Incidence of new major, minor, and any ECG abnormalities and CAN by treatment group was analyzed using logistic repeated-measures models at years 2 and 4 adjusted for baseline risk factors.
