VIDEO: Adverse ventilation effect means rethinking Cheyne-Stokes respiration




LONDON – The management of Cheyne-Stokes respiration in patients with heart failure with reduced ejection fraction needs to be reconsidered following the troubling outcome of a major trial that tested adaptive servo-ventilation as treatment for this symptom, Dr. Lars Køber commented during an interview at the annual congress of the European Society of Cardiology.

Cheyne-Stokes respiration, a form of central sleep apnea, differs from obstructive sleep apnea in that heart failure patients do not seem to derive symptomatic benefit from adaptive servo-ventilation treatment, but “physicians have thought they could treat this sleep apnea [with ventilation] and it would change prognosis,” said Dr. Køber. “Treatment of sleep apnea is possible, so physicians had started doing it.” But instead of helping patients, the trial results strongly suggested that patients were harmed by treatment, which was significantly linked with increased rates of both all-cause and cardiovascular mortality (N Engl J Med. 2015 Sep 1. doi: 10.1056/NEJMoa1506459).

In our video interview, Dr. Køber, professor of cardiology at Rigshospitalet and the University of Copenhagen, discusses the results and what the findings imply for future treatment.
