Abstract

The dependence of heart rate variability in patients with chronic heart failure (CHF) and type 2 diabetes on the severity of diabetic autonomic cardiac neuropathy (DACN) is described. 60 patients with Functional Class II–III CHF and type 2 diabetes, 30 of them had signs of DACN of varying severity were examined. The temporary values of heart rate variability, spectral characteristics were estimated, as well as the ratio of sympathetic and parasympathetic influences. It was revealed that patients with CHF and type 2 diabetes complicated by DACN had significant disturbance of autonomic regulation and the prevalence of adverse types of autonomic reactivity. At the same time, the severity of autonomic disorders increased with the aggravation of autonomic dysfunction.

Keywords
