Abstract
Quality of life (QoL) is reduced in patients with recurrent vasovagal (VVS) or unexplained syncope (US). Little is known concerning the natural evolution of QoL following diagnosis. Psychological factors contributing to QoL improvement, such as psychological distress and self-efficacy remain to be explored. The objective of this study is to examine whether QoL changes 2 months and 6 months following head-up tilt (HUT) testing as well as to determine whether psychological factors are predictive of changes in QoL. Seventy-three patients undergoing HUT for recurrent syncope were interviewed 1 month before as well as 2 months and 6 months following HUT, using semi-structured interviews and questionnaires. Pre-HUT QoL was significantly worse than at the 2-month (p = 0.000) and 6-month follow-ups (p = 0.000). Psychological distress at baseline was associated with worse QoL 2 months post-HUT (Beta = .280; p = .024), independently of socio-demographic and clinical factors. Improved self-efficacy at follow-up predicted improvements in QoL (Beta = −.186; p = .023). Two and 6 months post-HUT, QoL is mproved in patients with recurrent syncope. Better QoL is predicted by low psychological distress and a heightened sense of self-efficacy following HUT. Strategies for enhancing self-efficacy and reducing psychological distress could be an efficient way to promote QoL in patients suffering from recurrent syncope.
