Elucidating the effects of obstructive sleep apnea (OSA) on cardiovascular outcomes is crucial in risk assessments and therapeutic recommendations for affected individuals. The Sleep and Stent Study is a multi-center observational study investigating the relationships between OSA and cardiovascular outcomes in patients treated with percutaneous coronary intervention (PCI).

Primary Outcome Measures:
  • Number of Participants with Major Adverse Cardiac and Cerebrovascular events (MACCE) [ Time Frame: Two years ]
    Cardiovascular Death, Myocardial Infarction, Stroke/TIA, Unplanned revascularization

Secondary Outcome Measures:
  • Number of Participants with Adverse Events other than MACCE [ Time Frame: Two years ]
    All-cause mortality, Target vessel revascularization, Stent thrombosis, Hospitalization for heart failure.

Enrollment: 1815
Study Start Date: December 2011
Study Completion Date: September 2015
Primary Completion Date: September 2015 (Final data collection date for primary outcome measure)
OSA group
Patients found to have OSA based on an overnight sleep study
Non-OSA group
Patients found not to have OSA based on an overnight sleep study

Detailed Description:
Preliminary data suggest that OSA may lead to adverse cardiovascular outcomes after PCI. However, existing data were generated from small-scale, single-center studies. Therefore, in the Sleep and Stent Study, the investigators aim to conduct a large-scale multi-national cohort study to determine the association between OSA and the incidence of adverse cardiovascular outcomes over a long-term follow-up period. The investigators hypothesize that OSA is an independent risk factor for the development of major adverse cardiovascular and cerebrovascular events (MACCEs) in coronary artery disease patients treated with PCI. Results from the Sleep and Stent Study will advance the fundamental understanding of the burden and prognostic implications of OSA in patients undergoing PCI for coronary artery disease.

Ages Eligible for Study:   18 Years to 80 Years   (Adult, Senior)
Sexes Eligible for Study:   All
Accepts Healthy Volunteers:   No
Sampling Method:   Non-Probability Sample
Study Population
This is a prospective, observational multi-national cohort study of patients undergoing PCI for coronary artery disease. Adult patients undergoing clinically indicated PCI for coronary artery disease will be enrolled in the Sleep and Stent Study.

  • Successful PCI to at least one of the epicardial coronary arteries

Exclusion Criteria:

  • Known OSA on CPAP treatment
  • Intubation for mechanical ventilation
  • Intra-aortic balloon pump or other hemodynamic support device
  • Sedation or other muscle relaxant given before overnight sleep study
  • Perceived high risk of malignant ventricular arrhythmia
  • Cardiogenic shock with systolic blood pressure <90 mmHg
  • Clinical heart failure requiring oxygen supplementation
  • Pregnancy
  • History of malignancy (except non-melanoma skin cancer, cervical in-situ carcinoma, breast ductal carcinoma in situ or stage 1 prostate carcinoma)
