Prevalence and Dynamic of Sleep-disordered Breathing in Patients Pre and Post Heart Transplantation (HTx-HDZ-SDB-1)
May 5, 2021 updated by: Henrik Fox, MD, Heart and Diabetes Center North-Rhine Westfalia
Prevalence and Dynamic of Sleep-disordered Breathing in Patients Pre and Post Heart Transplantation - a Prospective Single Center Trial
Sleep-disordered breathing is believed to appear at a high prevalence in end-stage heart failure patients and the presence of sleep-disordered breathing has been associated with increased mortality.
This study is designed to investigate prevalence and dynamics of sleep-disordered breathing in end-stage heart failure patients pre and post heart transplantation.

Detailed Description
Sleep-disordered breathing is believed to appear at a high prevalence in end-stage heart failure patients and the presence of sleep-disordered breathing has been associated with increased mortality.
This study is designed to investigate prevalence and dynamics of sleep-disordered breathing in end-stage heart failure patients pre and post heart transplantation, as this topic is hardly studied yet and previous reports suggest changes in the entity of sleep-disordered breathing through heart transplantation.
The circumstances and the impact of sleep-disordered breathing or residuals in heart transplant patients is not well understood yet and will be subject of this study.
