Abstract :

Aim: This study purpose was to determine the autonomic nervous system (ANS) parameters that may differ the pathogenesis of transient ischemic attack (TIA) from stroke. Methodology: A prospective cohort study was conducted in the Department of Neurology and Neurosurgery at the Gomel State Medical University, Stroke Unit of the Gomel Regional Veterans Hospital, between May 2014 and March 2016 which includes 97 patients: TIA group - 13 patients and 84 stroke patients: 61 having size of stroke lower than 15 mm (lacunar stroke â?? LS), 23 having size of stroke greater than 15 mm (total stroke â?? TS). Heart rate variability (HRV) was used to describe status of the ANS. It was measured at 1st and 10th day after admission. Obtained HRV records were analyzed using the following four parameters: SDNN (standard deviation of the normal-to-normal R-R intervals, in ms), ??X (the difference between maximal and minimal R-R interval, in ms), Mo (mode of the duration of R-R intervals, in ms), AMo (amplitude of the R-R intervals mode, in percent). Results: For the HRV taken on the 1st day, the dependence between ??X (representing activity of parasympathetic part of ANS) and Mo (representing sympathetic part of ANS) was found to be significantly different for TIA and TS groups (p=0.016). Conclusion: The key difference between TIA and TS is a difference in the relationship between the humoral regulation of the activities of the ANS and the parasympathetic part activity at 1st day, which determines specific features of pathogenesis of the transient ischemia.
