Purpose
Recent studies have shown an association between obstructive sleep apnea (OSA) and coronary artery disease; however, the association between OSA and cardiac outcomes in patients after percutaneous coronary intervention (PCI) remains undetermined.
Methods
PubMed, EMBASE, and CENTRAL were searched from inception to July 2016 for cohort studies that followed up with patients after PCI, and evaluated their overnight sleep patterns within 1 month for major adverse cardiac events (MACEs) as primary outcomes including cardiac death, non-fatal myocardial infarction (MI), and coronary revascularization and secondary outcomes including re-admission for heart failure and stroke. Outcomes data were pooled using fixed-effect meta-analysis, and heterogeneity was assessed with the I
2 statistics. The methodological quality of the studies was assessed using the Newcastle-Ottawa Scale checklist, and publication bias was evaluated by a visual investigation of funnel plots.
Results
We identified seven pertinent studies including 2465 patients from 178 related articles. OSA was associated with MACEs (odds ratio [OR], 1.52, 95% confidence interval [CI], 1.20–1.93, I
2 = 29%), which included cardiac death (OR 2.05, 95% CI, 1.15–3.65, I
2 = 0%), non-fatal MI (OR 1.59, 95% CI, 1.14–2.23, I
2 = 15%), and coronary revascularization (OR 1.69, 95% CI, 1.28–2.23, I
2 = 0%). However, OSA was not associated with re-admission for heart failure (OR 1.71, 95% CI, 0.99–2.96, I
2 = 0%) and/or stroke (OR 1.68, 95% CI, 0.91–3.11, I
2 = 0%) according to the pooled results.
Conclusions
In patients after PCI, OSA appears to increase the risk of cardiac death, non-fatal MI, and coronary revascularization.
