Effects of Adaptive Servoventilation in Patients With Systolic Heart Failure and Sleep-Disordered Breathing
Study Overview
Status
Intervention / Treatment
Detailed Description
The study is intended to investigate therapeutic effects of adaptive servoventilation in patients with sleep-disordered breathing and chronic heart failure. These effects include short-/long-term effects on
- symptoms and quality of life
- physical and cardiac performance (6min walking test, cardiopulmonary exercise testing)
- echocardiographic parameters
- arrhythmias
- NT-proBNP
- Respiratory stability (blood gases, rebreathing test, VE/VCO2-slope in cardiopulmonary exercise testing)
- Compliance with ASV therapy
- Event free survival (death, heart transplantation, assist device implantation)
All of these data are also obtained in patients who basically meet the inclusion criteria but in whom sleep-disordered breathing was excluded by means of cardiorespiratory polygraphy or polysomnography and in patients with sleep-disordered breathing who do not undergo adaptive servoventilation for various reasons.
