Heart Rate Variability as Early Biomarker for the Evaluation of Diabetes Mellitus Progress

Abstract EN

According to the American Diabetes Association (ADA), the side effects of diabetes mellitus have recently increased the global health expenditure each year.

Of these, the early diagnostic can contribute to the decrease on renal, cardiovascular, and nervous systems complications.

However, the diagnostic criteria, which are commonly used, do not suggest the diabetes progress in the patient.

In this study, the streptozotocin model in mice (cDM) was used as early diagnostic criterion to reduce the side effects related to the illness.

The results showed some clinical signs similarly to five-year diabetes progress without renal injury, neuropathies, and cardiac neuropathy autonomic in the cDM-model.

On the other hand, the electrocardiogram was used to determine alterations in heart rate and heart rate variability (HRV), using the Poincaré plot to quantify the HRV decrease in the cDM-model.

Additionally, the SD1/SD2 ratio and ventricular arrhythmias showed increase without side effects of diabetes.

Therefore, the use of HRV as an early biomarker contributes to evaluating diabetes mellitus complications from the diagnostic.
