چکیده

Studies from the USA have reported that sleep apnoea is common in congestive heart failure (CHF), with Cheyne-Stokes respiration (CSR) being the most frequent type of sleep-disordered breathing (SDB) in these patients. Within the present study, the authors sought to assess the prevalence and type of SDB among CHF patients in Germany. A total of 203 CHF patients participated in this prospective multicentre study. All patients were stable in New York Heart Association classes II and III and had a left ventricular ejection fraction (LVEF)<40%. The patients were investigated by polygraphy and all data were centrally analysed. Patient enrolment was irrespective of sleep-related symptoms. The majority of patients were male with a mean age of 65 yrs and hospitalised. Of the 203 patients, 145 (71%) had an apnoea/hypopnoea index>10.h(-1), obstructive sleep apnoea (OSA) occurred in 43% (n=88) and CSR in 28% (n=57) of patients. The prevalence of sleep-disordered breathing is high in patients with stable severe congestive heart failure from a European population. As sleep-disordered breathing may have a negative impact on the prognosis of congestive heart failure, a sleep study should be performed in every patient with congestive heart failure and a left ventricular ejection fraction of <40%. This diagnostic approach should probably be adopted for all of these patients irrespective of the presence of sleep-related symptoms.

Treatment of obstructive and central sleep apnoea in heart failure: practical options

Sleep apnoea, both central and obstructive disordered breathing, commonly occurs in patients with heart failure. Obstructive sleep apnoea occurs both in systolic and diastolic heart failure and is best treated with nasal positive airway pressure devices. Central sleep apnoea occurs primarily in systolic heart failure and therapeutic options are

Sleep apnoea and the heart.

Sleep apnoea is associated with significant daytime functioning impairment and marked cardiovascular morbidities, leading to a significant increase in mortality. Sympathetic activation, oxidative stress and systemic inflammation have been shown to be the main intermediary mechanisms associated with sleep apnoea and intermittent hypoxia. There are now convincing data regarding the association be...

Impact of heart failure on quality of sleep.

Chronic heart failure is an important health problem associated with a high mortality and morbidity. Appropriate treatment reduces mortality and leads to improved exercise tolerance but many patients report poor quality of sleep. Sleep studies of patients with heart failure suggest that sleep disordered breathing is experienced in 50% of patients and is a powerful predictor of poor prognosis. S...

Sleep-Disordered Breathing—Do We Have to Change Gears in Heart Failure?

The majority of patients with heart failure have sleep-disordered breathing (SDB)-with central (rather than obstructive) sleep apnoea becoming the predominant form in those with more severe disease. Cyclical apnoeas and hypopnoeas are associated with sleep disturbance, hypoxaemia, haemodynamic changes, and sympathetic activation. Such patients have a worse prognosis than those without SDB. Mask...

Sleep apnoea screening in heart failure? Not until benefit is proven!

I n the current issue of European Respiratory Journal, in a German multicentre study, SCHULZ et al. [1] report a high frequency of sleep apnoea in patients with congestive heart failure (CHF). They also state that obstructive sleep apnoea (OSA) is more common in patients with heart failure than previously reported. Moving into the field of cardiology, the authors suggest that sleep studies shou...

Central sleep apnoea in congestive heart failure despite vagal denervation after bilateral lung transplantation.

Nonhypercapnic central sleep apnoea is a disorder of respiratory control characterized by hyperventilation previously attributed to the stimulation of either pulmonary vagal afferent nerve fibres or respiratory chemoreceptors. This report describes central sleep apnoea in a patient with congestive heart failure following bilateral lung transplant in whom pulmonary vagal afferent nerve activity ...
