Effects of Short-Term Continuous Positive Airway Pressure on Myocardial Sympathetic Nerve Function and Energetics in Patients With Heart Failure and Obstructive Sleep Apnea: A Randomized Study

Study Questions:

In patients with obstructive sleep apnea (OSA) and heart failure with reduced ejection fraction (HFrEF), what is the impact on myocardial energetics and sympathetic nervous system (SNS) activation of short-term treatment of OSA by nocturnal continuous positive airway pressure (CPAP)?
