Abstract

Background: Silent myocardial infarction and sudden death in diabetics are caused by the presence of cardiac autonomic neuropathy (CAN). Therefore, detecting cardiac dysautonomia early—when it is asymptomatic—will aid in slowing or stopping its progression. Methods A cross-sectional study was conducted to assess the prevalence of cardiovascular autonomic neuropathy in people with type 2 diabetes, correlate it with the duration of the disease, and explore into the relationship between cardiac autonomic dysfunction and corrected QT interval. Results: In the study population, the prevalence of definite CAN was 8%, 24% and 58% in group A, B and C respectively. The prevalence of definite CAN increases with increase in duration of diabetes. P value Conclusions: A significant correlation is present between Cardiovascular autonomic dysfunction and QTc prolongation. QTc interval in the ECG can be used to diagnose Cardiovascular autonomic neuropathy with a reasonable sensitivity and specificity.
