Effects of Adaptive Servoventilation in Patients With Systolic Heart Failure and Sleep-Disordered Breathing

September 2, 2019 updated by: Olaf Oldenburg, Ruhr University of Bochum
Prospective, follow-up registry of heart failure patients with or without sleep-disordered breathing (SDB). To test the hypothesis that treatment of nocturnal central sleep apnea with Cheyne-Stokes respiration by adaptive servoventilation (ASV) improves symptoms, cardiac performance and event-free survival.

Study Overview

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.
