Heart failure patients with sleep-disordered breathing (SDB) require assessment and treatment. Management includes addressing heart failure, weight loss, positional therapy, and positive airway pressure therapy for SDB.

Area of Science:

  • Cardiology
  • Sleep Medicine
  • Pulmonology

Background:

  • Sleep-related breathing disorders (SRBD) are prevalent in heart failure (HF) patients.
  • SRBD significantly worsen clinical outcomes in HF.
  • Daytime sleepiness and SRBD are common in HF patients.

Purpose of the Study:

  • To outline assessment and management strategies for SRBD in heart failure patients.
  • To provide recommendations for diagnosing and treating sleep-disordered breathing in this population.

Main Methods:

  • Assessment includes evaluating hemodynamic status and considering weight loss and positional modifications (elevated head of bed, avoiding supine position).
  • Polysomnography is recommended to diagnose the type and severity of SRBD.
  • Treatment options include nasal continuous positive airway pressure (CPAP) or bilevel positive airway pressure (BiPAP).

Main Results:

  • Heart failure exacerbations can precipitate central sleep apneas.
  • Weight loss and positional therapy are supportive measures.
  • Positive airway pressure therapies are effective treatments for SRBD in HF.

Conclusions:

  • Timely assessment and management of SRBD are crucial for improving outcomes in heart failure patients.
  • A multi-faceted approach addressing both HF and SRBD is necessary.
  • Nasal CPAP and BiPAP are key therapeutic interventions for SRBD in this cohort.
