Abstract:

Cardiovascular variability (blood pressure and heart rate) is affected by Diabetes Mellitus (DM). To study this effect, simultaneous non-invasive records of interbeat intervals (IBI) and beat-to-beat systolic blood pressure (SBP) variability of patients during supine, standing and controlled breathing tests were analyzed for recently diagnosed and long-standing DM patients comparing the results for 30 rigorously screened healthy subjects (Control). The most relevant changes as diabetes evolves are the loss of the cardio-respiratory modulation, standard deviation of the IBI detrended signal diminishes (Heart rate signal becomes more “rigid”) while for SBP increases, skewness for IBI approaches zero (Signal fluctuations gain symmetry), while for SBP becomes asymmetric and kurtosis increases (Fluctuations concentrate around the median). This may be due to a progressive decrease of parasympathetic and sympathetic activity to the heart and blood vessels as diabetes evolves.
