Screening for sleep-disordered breathing is recommended in patients with chronic heart failure

Screening for sleep-disordered breathing is recommended in patients with chronic heart failure.

The Canadian Continuous Positive Airway Pressure for Patients with Central Sleep Apnea and Heart Failure (CANPAP) trial was the first study to assess the effect of CPAP therapy in patients with chronic heart failure (CHF) and predominantly central sleep apnoea (CSA) on mortality [2]. Unfortunately, this study failed to demonstrate a prognostic benefit. However, there is ongoing debate as to how...

Sleep-Disordered Breathing in Patients with Heart Failure

Breathing disturbances during sleep play a significant role in patients with cardiac diseases due to their high prevalence and impact on outcome. Obstructive sleep apnea (OSA) is a major risk factor of arterial hypertension and is associated with atrial fibrillation. A majority of heart failure (HF) patients suffer from OSA or central sleep apnoea (CSA), both associated with impaired prognosis....

Screening for Sleep-Disordered Breathing in Patients Hospitalized for Heart Failure.

S leep-disordered breathing (SDB) represents a highly prevalent comorbidity in heart failure (HF) patients. Approximately 45% of stable patients with either heart failure with reduced ejection fraction (HFrEF) or preserved ejection fraction have moderate to severe obstructive sleep apnea (OSA) or central sleep apnea (CSA) (1,2), and this prevalence is even greater in patients with acutely decom...

pretest probability of moderate to severe obstructive sleep apnea.6 A randomized control study is a well-designed clinical trial to examine clinical problems.7 However, our study was a prospective but not a randomized trial and was performed in a single center with a small number of patients. We agree that a study with a better design and larger sample size may solve the issues raised. Finally,...
