Future of Sleep-Disordered Breathing Therapy Using a Mechanistic Approach

Area of Science:

• Cardiology
• Sleep Medicine
• Pulmonology

Background:

• Sleep disordered breathing (SDB) is highly prevalent in cardiovascular disease (CVD) patients, with a potential bidirectional relationship.
• SDB is frequently underdiagnosed and undertreated, partly due to low satisfaction with current therapies.
• Treatment discordance with SDB's complex pathophysiology is a key barrier.

Purpose of the Study:

• To review the pathophysiological characteristics of SDB.
• To propose an individualized treatment approach for SDB based on underlying mechanisms.
• To explore potential improvements in SDB therapy adherence and success.

Main Methods:

• Literature review of SDB pathophysiology.
• Classification of SDB mechanisms: upper airway anatomy, muscle dysfunction, ventilatory control.
• Discussion of current SDB treatment limitations, primarily positive airway pressure therapy.

Main Results:

• SDB involves multiple pathophysiological mechanisms, including anatomical, muscular, and neural factors.
• Current SDB treatments, mainly positive airway pressure, have limitations.
• Individualized treatment strategies tailored to specific SDB mechanisms are proposed.

Conclusions:

• Understanding SDB's diverse pathophysiological mechanisms is crucial.
• An individualized, mechanism-based treatment approach for SDB warrants further investigation.
• This tailored approach may enhance patient adherence and therapeutic outcomes in SDB management.
