Abstract
The aim of this study was to evaluate the relationship between Shannon entropy (SE) and symbolic analysis (SA) of heart rate variability at rest in 3 groups: patients with coronary artery disease (CAD), CAD with diabetes mellitus (CAD-DM), and healthy individuals (H). We evaluated 44 men into the groups (CAD, n=16, CAD-DM, n=13 and H, n=15). The R-R intervals (R-Ri) were recorded at rest in the supine position for 15 minutes. SA analysis classified patterns of R-Ri according to the number of variations into stable and unstable patterns. Significant and negative correlation was found between SE and the percentage of stable patterns for CAD and CAD-DM. Positive correlation was found between SE and the percentage of unstable patterns in all the groups. We conclude that complexity of cardiovascular control had a positive relationship with the cardiac parasympathetic modulation in all groups and negative relationship with the sympathetic modulation in CAD and CAD-DM groups.
