Abstract

Study Objectives: To determine the effect of continuous positive airway pressure (CPAP) treatment on health-related quality of life (HRQoL) in adults with coronary artery disease (CAD) and nonsleepy obstructive sleep apnea (OSA). Methods: This was a secondary outcome analysis of the RICCADSA trial, conducted in Sweden between 2005 and 2013. Adults with CAD, nonsleepy OSA (apnea-hypopnea index [AHI] ≥ 15 events/h; Epworth Sleepiness Scale [ESS] score < 10) and complete Short-Form (SF)-36 questionnaires at baseline and after 12 months were included. Patients were randomized to CPAP (n = 102) or no CPAP (n = 104). The primary outcome was the between-group difference in absolute change in the SF-36 components. Within-group changes as well as variables associated with absolute change in the domains in the entire population were also tested. Results: Mean SF-36 scores were similar at baseline, ranging from 44.9 ± 9.6 to 92.2 ± 15.8 in various domains, and between-group changes from baseline were not statistically significant at 1 year. There was a significant increase in Role physical, Vitality, Role emotional, Mental health and Mental Component Summary (MCS), and a decrease in Bodily pain and General health scores in the CPAP group. The change in Physical Component Summary (PCS) was determined by female sex (beta coefficient −0.19, 95% confidence interval [CI] −7.25 to −0.98, P =.010), baseline AHI (beta coefficient −0.19, 95% CI −0.21 to −0.03, P =.009), CPAP use (h/night) (beta coefficient −0.16, 95% CI −0.93 to −0.06, P =.028), and acute myocardial infarction at baseline (beta coefficient 0.18, 95% CI 0.59 to 5.19, P =.014). Determinants of the change in MCS from baseline were change in the ESS score (beta coefficient −0.14, 95% CI −0.87 to −0.01, P =.054) and change in the Zung Self-rated Depression Scale scores (beta coefficient −0.33, 95% CI −0.58 to −0.24, P < .001). Conclusions: Assignment to CPAP treatment compared to no CPAP had no significant effect on HRQoL as measured by the SF-36 in adults with CAD and nonsleepy OSA. Although several components of the SF-36 scores were improved within the CPAP group, CPAP use was associated with a decrease in PCS. The improvement in MCS was determined by the improvement in daytime sleepiness and depressive mood. Clinical Trial Registration: Registry: ClinicalTrials.gov; Identifier: NCT00519597.
