Differing Effects of Adaptive Servoventilation and Continuous Positive Airway Pressure on Muscle Sympathetic Nerve Activity in Patients With Heart Failure Ryuichi Ushijima, MD; Shuji Joho, MD; Takashi Akabane, MD; Yoshitaka Oda, MD; Hiroshi Inoue, MD

Background:  Long-term adaptive servoventilation (ASV) increases cardiac function more effectively than continuous positive airway pressure (CPAP), possibly via alleviation of sympathetic overactivation. The present study evaluated the effect of ASV and CPAP at comparable pressure on muscle sympathetic nerve activity (MSNA) in patients with heart failure (HF) and with or without periodic breathing (PB). Methods and Results:  A total of 57 patients with HF (ejection fraction
