| Description
| - Aims: Orthostatic stimuli are known to elicit changes in vasoactive peptide levels. The hypothesis of no difference in adrenomedullin and/or galanin levels in patients with recurrent vasovagal syncope and healthy controls was tested in a passive 35-min head-up tilt test (HUTT). Methods: Twenty eight persons (14 patients and 14 healthy controls) were tested in a 35-min/60° head-up tilt test with telemetry monitoring. Three blood samples were evaluated for each person during the HUTT. Plasma levels of adrenomedullin and galanin were analysed by the Kruskal-Wallis test for all sampling periods. Vagal influence was indirectly assessed by the break index. Results: There were no significant differences between groups in median values for either adrenomedullin or galanin plasma levels (all 6 p-values were greater than 0.4). For adrenomedullin, no significant difference between groups was found. For galanin, the rate of change between the 1st and 2nd measurement was significantly greater for patients (P=0.04), regardless of HUTT result but between the 2nd and 3rd measurement it was insignificant (P=0.36). In the group of positive cases, the break index increased significantly (P=0.02). Conclusion: We confirmed that there is a different galanin secretion pattern during orthostatic provocation in patients with recurrent vasovagal syncope than healthy individuals. For adrenomedullin, no significant difference was found. A significant increment of the break index confirmed increased vagal influence in the subgroup of positive cases.
