ResMed today announced data from two studies about sleep-disordered breathing (SDB) in chronic heart failure will be presented at the 64th Annual Scientific Sessions of the American College of Cardiology, from March 14 through 16.

“The data we are presenting are important because they point toward a connection between breathing disorders in sleep, like sleep apnea, and chronic heart failure,” says ResMed chief medical officer, Glenn Richards, MD, in a release. “We look forward to learning the results of our landmark clinical study called SERVE-HF, that examines whether addressing sleep-disordered breathing in people with chronic heart failure improves survival.”

Final data from nearly 7,000 patients in a German registry of more than 10,000 patients with stable chronic heart failure showed that SDB was present in nearly one out of two people (46%). Prevalence of SDB increased rapidly with age. Other risk factors include male gender, more severe heart failure, atrial fibrillation, and increased weight.

This data will be presented in a poster session by Olaf Oldenburg, senior cardiologist in the Department of Cardiology at the Heart and Diabetes Center North Rhine-Westphalia, Bad Oeynhausen, Germany, on March 16 from 9:45 AM to 10:30 AM. (Session 1252, Poster 212; Prevalence and Predictors of Sleep-Disordered Breathing in Patients with Stable Chronic Heart Failure: Final data of the SchlaHF Registry; Poster Hall B1)

Data from an American study suggests that treatment of SDB may reduce hospital admission rates in patients with chronic heart failure. Patients compliant with PAP therapy had significantly reduced hospital visits in the 6 months after starting therapy compared to the 6 months before therapy. A comparable group who were not compliant with PAP therapy had no change in frequency of hospital visits.

This data will be presented in a poster session by Dr Sunil Sharma, associate professor in the Department of Medicine at Thomas Jefferson University on March 14 from 3:45 PM to 4:30 PM.
