Dynamics of psychovegetative syndrome in patients during the period of rehabilitation after coronary bypass

OBJECTIVE: The study was to investigate the role of moderate and severe anxiety in development of psychovegetative syndrome after coronary artery bypass graft (CABG), to describe the nature and direction of resulting autonomic dysfunction and to study possibilities of anti-ancient therapy. MATERIAL AND METHODS: We studied 33 patients (19 - in the main group, 14 - in the comparison group) on average 13 days after CABG and in dynamics in the process of early postoperative rehabilitation. A point assessment of the psychological and autonomic spheres, and sleep quality was made. Indicators of vegetative tone and vegetative regulation were studied, in particular, temporal and spectral indicators of heart rate variability. In addition to basic therapy for ischemic heart disease (IHD), the patients in main group were received therapy with alimemazine. RESULTS: In most cases, after CABG, moderate situational and personal anxiety and sleep disturbances were recorded in combination with autonomic dysregulation with a predominance of sympathetic influences from the autonomic nervous system (ANS). Adding to the basic therapy of IHD among patients of the main group of the drug with a mild anti-anxiety effect, allowed for 2 weeks to significantly reduce the level of anxiety and correct the existing autonomic disorders. CONCLUSION: This study found that patients with an increased level of anxiety after CABG are characterized by the formation of a psychovegetative syndrome with a predominance of sympathetic activity. The using anti-anxiety drugs can reduce the severity of anxiety and autonomic dysfunction, which can probably become a factor contributing to the successful rehabilitation of patients after CABG in the early and late postoperative periods, and the prevention of progression of IHD.
