BACKGROUND: Sleep-disordered breathing (SDB), including central and obstructive sleep apnea, is a marker of poor prognosis in heart failure (HF) and may worsen cardiac dysfunction over time. Treatment of SDB with adaptive servoventilation (ASV) may reverse pathologic cardiac remodeling in HF patients. METHODS: The Cardiovascular Improvements with Minute Ventilation-targeted Adaptive Servo-Ventilation Therapy in Heart Failure (CAT-HF) trial randomized patients with acute decompensated HF and confirmed SDB to either optimal medical therapy (OMT) or treatment with ASV and OMT...

Central sleep apnoea (CSA) occurs in a large proportion of HF patients. CSA has clear detrimental effects, resulting in intermittent hypoxia and sympathetic activation, and is associated with significant morbidity and mortality. Treatment options are limited following the results of a recent trial in which adaptive servo-ventilation resulted in an increase in cardiovascular mortality. Ongoing studies utilising other forms of positive airway pressure may provide additional insight into the results of this trial...

As seen in this CME online activity (available at http://journal.cme.chestnet.org/sv-sleep-disorder), central sleep apnea (CSA) is associated with increased mortality in patients with heart failure (HF), and it has been thought that treatment of CSA may improve underlying HF. Positive airway pressure therapy, specifically auto-servoventilation (ASV), can not only suppress abnormal breathing patterns but has been reported to improve cardiac function in HF patients with CSA. In patients with HF and with CSA unsuppressed with CPAP, newer ASV use has been associated with significant CSA improvement; in addition, several studies have reported efficacy of ASV in the treatment of underlying cardiac dysfunction in HF patients with CSA...

Clinical advantages in the adaptive servo-ventilation (ASV) therapy have been reported in selected heart failure patients with/without sleep-disorder breathing, whereas multicenter randomized control trials could not demonstrate such advantages. Considering this discrepancy, optimal patient selection and device setting may be a key for the successful ASV therapy. Hemodynamic and echocardiographic parameters indicating pulmonary congestion such as elevated pulmonary capillary wedge pressure were reported as predictors of good response to ASV therapy...

Sleep-disordered breathing (SDB) is a risk factor for cardiovascular disease including acute coronary syndrome and acute myocardial infarction, and treating SDB prevents their development and recurrence and improves a patient's prognosis. Therefore, SDB is considered a therapeutic target for cardiovascular disease. In 2010, the Japanese Circulation Society published guidelines for the diagnosis and treatment of SDB in patients with cardiovascular disease. However, therapeutic intervention for patients with SDB was recently reported not to suppress the development or deterioration of cardiovascular disease in three middle- to large-sized randomized clinical trials: the SERVE-HF trial, which examined the effects of adaptive servo-ventilation (ASV) on patients with chronic heart failure (CHF) and central sleep apnea; the CAT-HF trial, which examined the effects of ASV therapy on patients with CHF after acute deterioration; and the SAVE study, which examined the secondary preventive effect of continuous positive airway pressure (CPAP) on patients with ischemic heart disease who had mild to moderate obstructive sleep apnea...

Central sleep apnea (CSA) is common in heart failure (HF) patients. Traditional treatment of CSA, including continuous positive airway pressure (CPAP), adaptive servo ventilation (ASV), oxygen therapy, and CO2 inhalation, has respective limitations. Transvenous phrenic nerve stimulation (PNS), a novel therapeutic approach for CSA, was proved to be effective and safe. The remedē® system and related transvenous PNS methods was approved by FDA in 2017, for treating moderate to severe CSA.

PURPOSE OF REVIEW: This paper reviews treatment options for sleep disordered breathing (SDB) in patients with heart failure. We sought to identify therapies for SDB with the best evidence for long-term use in patients with heart failure and to minimize uncertainties in clinical practice by examining frequently discussed questions: what is the role of continuous positive airway pressure (CPAP) in patients with heart failure? Is adaptive servo-ventilation (ASV) safe in patients with heart failure? To what extent is SDB a modifiable risk factor? RECENT FINDINGS: Consistent evidence has demonstrated that the development of SDB in patients with heart failure is a poor prognostic indicator and a risk factor for cardiovascular mortality...

Adaptive servo-ventilation (ASV) therapy is a novel modality of noninvasive positive pressure ventilation and is now widely utilized to treat patients with chronic heart failure (CHF). However, there has been no clinical study of the effect of ASV therapy on readmission and cost-effectiveness for the treatment of CHF. The present study was conducted to evaluate the clinical efficacy and cost-effectiveness of home ASV therapy in 45 patients with a history of two or more admissions a year for worsening CHF. Seven patients refused to undergo chronic ASV therapy and three died...

Noninvasively applied positive airway pressure therapy (PAP) is available in 3 basic modes: continuous positive airway pressure (CPAP), bi-level positive airway pressure (BPAP), and adaptive servo-ventilation. These are in widespread use in home and hospital settings to treat a variety of disorders of ventilation or gas exchange, including obstructive sleep apnea, sleep-related hypoventilation, periodic breathing, acute and chronic hypercapnic respiratory failure, and acute respiratory failure. They are increasingly being used perioperatively to prevent or treat upper airway obstruction, hypoventilation, and periodic breathing, and they have been found to improve postoperative outcomes in the case of obstructive sleep apnea...

Background: Acute effects of positive airway pressure (PAP) [including continuous PAP (CPAP) and adaptive servo-ventilation, an advanced form of bi-level PAP] on functional mitral regurgitation (fMR) in patients with heart failure (HF) with left ventricular (LV) systolic dysfunction remain unclear. Thus, whether PAP therapy reduces fMR in such patients with HF was investigated. Methods and Results: Twenty patients with HF and LV systolic dysfunction defined as LV ejection fraction (LVEF) <50% (14 men; mean LVEF, 35...

Study objectives: Patients with comorbid posttraumatic stress disorder (PTSD) and obstructive sleep apnea (OSA) manifest low adherence to continuous positive airway pressure (CPAP) due to fixed, pressure-induced expiratory pressure intolerance (EPI), a subjective symptom and objective sign aggravated by anxiety sensitivity and somatosensory amplification. As advanced PAP therapy modes (ie, auto-bilevel PAP [ABPAP] or adaptive servo-ventilation [ASV]) may address these side effects, we hypothesized such treatment would be associated with decreased expiratory intolerance and increased adherence in posttraumatic stress patients with co-occurring OSA...

RATIONALE: Adaptive servo-ventilation (ASV), a novel respiratory support therapy for sleep disorders, may improve cardiac function in heart failure (HF). However, the reasons that ASV improves cardiac function have not been fully studied especially in sympathetic nervous function (SNF). The purpose of the present study was to investigate the effects of ASV therapy on cardiac SNF in patients with HF. METHODS: We evaluated ASV therapeutic effects before and 6 months after ASV therapy in 9 HF patients [57...
