Abstract
TORRES-LEYVA, Michel et al. Nonlinear dynamics of cardiovascular autonomic regulation during the sustained weight test in patients with type 2 diabetes mellitus. Rev. Colomb. Cardiol. [online]. 2021, vol.28, n.5, pp.421-430. Epub Nov 29, 2021. ISSN 0120-5633. https://doi.org/10.24875/rccar.m21000079.
Introduction:
The analysis of non-linear dynamics of cardiovascular autonomic regulation based on heart rate variability has not been previously studied in patients with type 2 diabetes mellitus using the sustained weight test as an inducer of cardiovascular hyperreactivity.
Objective:
To determine the variations in the non-linear dynamics of cardiovascular autonomic regulation during the sustained weight test in patients with type 2 diabetes mellitus.
Method:
A quasi-experimental, before-after study with a control group, from June-August 2018, at the No. 1 School of Medicine in Santiago de Cuba. We worked with 15 patients suffering from type 2 diabetes mellitus without other associated disease and 15 healthy subjects, to whom the sustained weight test was applied.
Results:
In patients with diabetes mellitus, when performing the sustained weight test, there was a significant increase in the hemodynamic parameters TAS, TAD, TAM and FC. In the sample entropy, a parameter that evaluates the adaptability of the systems, there is a significant decrease (2.28 ± 0.33 vs. 1.83 ± 0.47 ms; p = 0.003143). The value of the C statistic of the sample entropy at baseline was established at 0.973, being the variable with the highest predictive capacity.
Conclusions:
In patients with type 2 diabetes mellitus during the sustained weight test, there was a decrease in the complexity of cardiovascular autonomic regulation, the basal sample entropy was the indicator of greater efficacy in the identification of cardiovascular autonomic alterations.
