About this study

Official title: Impact of Obstructive Sleep Apnea on Cardiovascular Outcomes in Patients Treated With Percutaneous Coronary Intervention

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).

Read the 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.

Questions about this trial

What is this clinical trial studying?

An observational study of Obstructive Sleep Apnea, run by National University of Singapore at 1 site in Singapore.

The full registered description is in the About this study section and the official record.

Who may be eligible to take part?

The sponsor lists 2 inclusion and 9 exclusion criteria. Eligibility is decided by the study team after screening, so read the full criteria and contact a listed site.

Is this clinical trial currently recruiting?

The record says: finished, as of the sponsor's last update on 23 Feb 2017. Status can change between updates, so confirm with the study contact before making plans.

Where is the study taking place?

The record lists 1 site in Singapore. Whether a site is taking part right now should be confirmed with that site. See every site.

What are the possible benefits and risks?

They depend on the study and the treatment, and no study can promise a benefit. The study team explains the known risks during informed consent, before anyone joins; the record itself does not list them.

Are results available for this study?

The study is completed, but results are not available in the source record. That does not mean the treatment did or did not work.

How can a doctor refer a patient or contact the research team?

The record lists no contact. The official record names the sponsor, who can be asked directly. AzTrials does not enrol participants or take referrals.

What does the primary outcome measure?

Number of Participants with Major Adverse Cardiac and Cerebrovascular events (MACCE) (time frame: Two years). It is what the study was designed to measure, not a finding.

Where can I read the original study information?

On the ClinicalTrials.gov record for NCT02215317, which also lists 1 linked publication.

Does a listing mean the treatment is approved or proven to work?

No. A listing means the study is registered. It does not show that the treatment is safe, works, or is approved by a regulator.

How often is this information updated?

AzTrials copies changed records from ClinicalTrials.gov every night and reloads the whole registry every week. The sponsor last updated this record on 23 Feb 2017.
