Sleep-disordered breathing is one of the important factors contributing to the development and/or progression of heart failure (HF). This condition is related to recurring attacks of apnea, hypopnea, and hyperpnea, sleep disruptions, arousals, intermittent hypoxemia, hypocapnia, and hypercapnia, and intrathoracic pressure changes. Obstructive sleep apnea (OSA) is characterized by recurrent upper airway obstruction (apnea and hypopnea), increased breathing effort against totally or partially occluded upper airway, and sleep disruptions. Cardiovascular consequences are the most serious complications of OSA and include acute myocardial infarction, heart failure, left/right ventricular dysfunction, arrhythmias, stroke, and systemic and pulmonary hypertension. Cheyne-Stokes respiration and central apneas may also occur in patients with HF. This article reviews the most recent information on the physiopathology, diagnosis, and treatment modalities of obstructive and central apneas in patients with HF.
