Introduction:

an important cardiovascular risk factor is diabetes; however, the analysis of cardiac dynamics is not clear when evaluating quantitatively the impact of this disease.

Objective:

to determine the clinical applicability of a methodology based on an exponential chaotic law to analyze the cardiac dynamics of diabetic patients.

Method:

10 Holter records were taken from patients with type 2 diabetes mellitus, 10 from patients with cardiovascular diseases and 10 normal. Afterwards, attractors were constructed with the heart rate values and the occupation spaces were calculated for each case. Sensitivity and specificity calculations and diagnostic agreement were performed.

Results:

the normal records had occupation spaces in the Kp grid greater than 200; records of people with diabetes ranged from normal to acute heart disease. Sensitivity and specificity of 100% were obtained.

Conclusion:

this methodology detects chronic and acute alterations in patients with type 2 diabetes mellitus.
