[Central sleep apnea in patients with chronic heart failure].

Cheyne-Stokes respiration (CSR) is a form of sleep-disordered breathing seen in approximately half of patients with chronic heart failure and low left ventricular ejection fraction. The authors describe clinical features of CSR, mortality rate, treatment variants. Effects of continuous positive airway pressure (CPAP), bi-level ventilation, adaptive servoventilation (ASV) in patients with CSR and chronic heart failure are discussed. Diuretic acetazolamide is one more therapeutic option for CSR. It improves central sleep apnea and related daytime symptoms in patients with heart failure.
