Treatment of OSA Reduces the Risk of Repeat Revascularization After Percutaneous Coronary Intervention

BACKGROUND The impact of OSA treatment with CPAP on percutaneous coronary intervention (PCI) outcomes remains largely unknown. METHODS Between 2002 and 2012, we identified 390 patients with OSA who had undergone PCI. OSA was diagnosed through in-laboratory sleep studies and defined by an apnea-hypop...

Zusammenfassung:BACKGROUND The impact of OSA treatment with CPAP on percutaneous coronary intervention (PCI) outcomes remains largely unknown. METHODS Between 2002 and 2012, we identified 390 patients with OSA who had undergone PCI. OSA was diagnosed through in-laboratory sleep studies and defined by an apnea-hypopnea index ≥ 5 events/h. The cohort was divided into three groups: (1) moderate-severe OSA successfully treated with CPAP (n = 128), (2) untreated moderate-severe OSA (n = 167), and (3) untreated mild OSA (n = 95). Main outcomes included repeat revascularization, major adverse cardiac events (MACEs) (ie, death, nonfatal myocardial infarction, repeat revascularization), and major adverse cardiac or cerebrovascular events (MACCEs). The median follow-up period was 4.8 years (interquartile range, 3.0-7.1). RESULTS The untreated moderate-severe OSA group had a higher incidence of repeat revascularization than the treated moderate-severe OSA group (25.1% vs 14.1%, P = .019). There were no differences in mortality ( P = .64), MACE ( P = .33), and MACCE ( P = .76) among the groups. In multivariate analysis adjusted for potential confounders, untreated moderate-severe OSA was associated with increased risk of repeat revascularization (hazard ratio, 2.13; 95% CI, 1.19-3.81; P = .011). CONCLUSIONS Untreated moderate-severe OSA was independently associated with a significant increased risk of repeat revascularization after PCI. CPAP treatment reduced this risk.
