Background: Hypertension, diabetes and obesity are not isolated findings, but a series of interacting interactive physiologic derangements. Taking into account genetic background and lifestyle behavior, AI (autonomic imbalance) could be a common root for RHTN (resistant hypertension) or RHTN plus type 2 diabetes (T2D) comorbidity development. Moreover, circadian disruption can lead to metabolic and vasomotor impairments such as obesity, insulin resistance and resistant hypertension.

The function of the autonomic nervous system was assessed in 23 patients with dysmotility-like functional dyspepsia and 12 healthy volunteers by analysis of 24-hr heart rate variability and a battery of five standardized sympathetic and parasympathetic cardiovascular reflex tests. Measures of heart rate variability were obtained by analysis of ambulatory electrocardiographic recordings using both the time and the frequency domain methods. The values of parameters reflecting vagal activity (HF, rMSSD) were significantly lower in patients with functional dyspepsia.
