The Impact of Low Flow Nocturnal Oxygen Therapy on Hospital Admissions and Mortality in Patients with Heart Failure and Central Sleep Apnea (LOFTHF) study is a research study for patients with heart failure and a specific type of sleep apnea, central sleep apnea (CSA). This project is designed to find out whether nighttime oxygen therapy improves heart failure and well-being in patients with heart failure and CSA.
Many people with heart failure also have central sleep apnea (CSA). Sleep apnea is a disorder where breathing pauses occur during sleep. Sleep apnea can cause poor sleep quality and worsen heart function. However, there are no documented effective treatments for patients with heart failure and CSA. Nighttime use of supplemental oxygen may improve heart failure and general health, but has not been rigorously studied. The LOFT-HF study is designed to help us understand how to better treat patients with heart failure who have sleep apnea.
During this study you will:
Participants will be assessed for CSA based on a prior sleep study or an at-home sleep study completed during study participation. Individuals will then be randomly placed into one of two groups:
