Background
Sleep-disordered breathing (SDB), comprising obstructive sleep apnea (OSA) and central sleep apnea (CSA), could promote left ventricular (LV) remodeling and systolic dysfunction.
Objectives
The authors tested the hypothesis, in the ADVENT-HF (Adaptive Servo-ventilation for Sleep-disordered Breathing in Patients with Heart Failure with Reduced Ejection Fraction) trial, that SDB is associated with reversible impairment of LV structure and function.
Methods
Participants underwent echocardiography (ejection fraction ≤45%) and polysomnography. They were classified as no-SDB (apnea-hypopnea index [AHI] <15/h); OSA (AHI ≥15/h with ≥50% of events obstructive), or CSA (AHI ≥15 with >50% of events central). Those with SDB were randomized to a control group or to peak-flow-triggered adaptive servo-ventilation (ASVPF) to treat SDB and, in them, echocardiography was repeated 6 months later.
Results
Subjects with OSA (n = 543) had similar LV structure and function to those without SDB (n = 56). Subjects with CSA (n = 201) had greater LV mass index and lower LV ejection fraction than the other groups. LV volumes were higher in the CSA than in the OSA group (P < 0.05 for all). ASVPF abolished SDB, but had no significant effect, whether evaluated by allocation or adherence, 6 months post-randomization on LV structure or function for the entire cohort (n = 549), or either subgroup.
Conclusions
Among patients with heart failure with reduced ejection fraction, those with OSA had similar LV structure and function to those without SDB. Patients with CSA had greater LV remodeling and systolic dysfunction than those with OSA or without SDB. Six months of SDB suppression of OSA and CSA by ASVPF had no impact on LV structure or function.

<div><h3>Background</h3><div>Older age is associated with a high prevalence of comorbidities and worse cardiovascular (CV) outcomes in patients with heart failure (HF) with reduced ejection fraction. Omecamtiv mecarbil, a selective cardiac myosin activator, exerts minimal effects on blood pressure and heart rate and has limited extracardiac activity, and thus it may be well-tolerated in older individuals. The safety profile and clinical benefits of omecamtiv mecarbil across the age spectrum remain uncertain.</div></div><div><h3>Objectives</h3><div>This study aims to assess CV outcomes, treatment response, and tolerability to omecamtiv mecarbil according to age in patients enrolled in the GALACTIC-HF (Global Approach to Lowering Adverse Cardiac Outcomes Through Improving Contractility in Heart Failure) trial.</div></div><div><h3>Methods</h3><div>GALACTIC-HF was a randomized, global, double-blind clinical trial testing omecamtiv mecarbil vs placebo in patients with symptomatic HF with reduced ejection fraction. Key eligibility criteria included an age between 18-85 years, elevated natriuretic peptides, and a left ventricular ejection fraction (LVEF) ≤35%. We examined the treatment effect of omecamtiv mecarbil vs placebo for the primary endpoint of CV death or first HF event (hospitalization or urgent visit for HF) in both the overall population and the severe HF subgroup (LVEF ≤30%, NYHA functional class III/IV, HF hospitalization within 6 months), as well as safety outcomes according to prespecified age groups (<65 or ≥65 years).</div></div><div><h3>Results</h3><div>A total of 8,232 patients (age 64.5 ± 11.4 years, 54.5% ≥65 years, 21% female) were included. The rate of the primary outcome was 21.4 per 100 patient years (py) in those <65 years of age and 28.8 per 100 py in those ≥65 years of age. The treatment effect of omecamtiv mecarbil for the primary outcome (HR: 0.92 [95% CI: 0.86-0.99]; <em>P =</em> 0.03) was consistent in age groups (<em>P</em><sub>interaction</sub> = 0.76) and irrespective of age as a continuous variable (<em>P</em><sub>interaction</sub> = 0.19, after adjusting for treatment interactions with known modifiers of the effects of omecamtiv mecarbil: LVEF and baseline atrial fibrillation status). In patients with severe HF, omecamtiv mecarbil significantly reduced the risk of the primary outcome in both patients <65 years of age (HR: 0.77 [95% CI: 0.64-0.92]) and those ≥65 years of age (HR: 0.83 [95% CI: 0.71-0.97]; <em>P</em><sub>interaction</sub> = 0.47).
