Heart rate variability evaluation in the assessment of cardiac autonomic neuropathy in patients with type 2 diabetes

Presented cross-sectional study in type 2 diabetes mellitus demonstrated a significant autonomic dysfunction in majority patients examined, independently of diabetes duration. It supports the recommendation to assess the ANS integrity in type 2 diabetes already at diagnosis, within the initial staging of the illness. The severity of CAN correlates well with metabolic control of diabetes as evaluated by glycated hemoglobin.
