| Summary: | Background: 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. Methods: 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). OSA was diagnosed when the apnea-hypopnea index (AHI) was ≥5 events/hour. ISR was defined as >50% restenosis of the vessel diameter in which the DES was implanted. To explore the association between OSA and ISR among patients with CHD, multivariate logistic regression models were developed and utilized. Results: This study enrolled 206 individuals who were diagnosed with CHD, with a mean age of 62.01 ± 10.27 years, and males constituted 76.2% of the patient population. After a median follow-up period of 15 months following DES implantation, there was a significant increase in the incidence of ISR among patients with moderate to severe OSA, increasing from 10.9% to 31.3% (p < 0.001). According to the fully adjusted model, the occurrence of ISR was found to be independently associated with the presence of OSA (OR: 3.247, 95% CI: 1.373–7.677, p = 0.007). Conclusions: In individuals who underwent elective drug-eluting stenting, OSA is an independent risk factor for ISR. |
