biostudies-literatureUnknown26(1)Yang W<h4>Background</h4>Extensive research has established obstructive sleep apnea (OSA) as a contributing factor to numerous cardiovascular and cerebrovascular diseases. However, whether OSA affects in-stent restenosis (ISR) after elective drug-eluting stenting is unclear. Therefore, the objective of this study was to examine the impact of OSA on ISR in patients with coronary heart disease (CHD) who underwent successful elective drug-eluting stent (DES) implantation.<h4>Methods</h4>This study retrospectively analyzed CHD patients who successfully underwent elective coronary stent implantation and overnight sleep breathing monitoring and were readmitted for coronary angiography due to symptoms of CHD at 12 to 26 months after percutaneous coronary intervention (PCI).
