BACKGROUND Central sleep apnea, often found in patients with chronic heart failure (CHF), has a high risk of poor prognosis. METHODS AND RESULTS This study involved 20 patients with CHF (left ventricular ejection fraction (LVEF) <45%, M/F =19/1, age 65+/-10 years) and an apnea-hypopnea index (AHI) >5 times/h who were divided into 2 groups: 10 patients treated with nocturnal home oxygen therapy (HOT) and 10 patients without HOT (non-HOT). All patients had dilated cardiomyopathy and underwent… CONTINUE READING
