Relationship Between Obstructive Sleep Apnea and Coronary Atherosclerosis — IDEAS-OSA  

Coronary Artery Disease Clinical Trial

Official title:
Intravascular Ultrasound Diagnostic Evaluation of Atherosclerosis in Singapore- Obstructive Sleep Apnea (IDEAS-OSA) Study

Clinical Trial Summary

Obstructive sleep apnea (OSA) is a respiratory disorder of sleep characterized by recurrent episodes of complete or partial upper airway obstruction, leading to intermittent oxygen deprivation. This results in sympathetic activation and surges in blood pressure, production of vasoactive substances, as well as activation of the inflammatory and procoagulant pathways. Epidemiological evidence indicates the prevalence of OSA is higher in patients with coronary artery disease than in the general population. The investigators recently showed that 65.7% and 41.9% of the Singapore patients admitted with myocardial infarction were found to have previously undiagnosed OSA and severe OSA, respectively. In a 10-year follow-up epidemiological study, OSA was independently associated with a higher prevalence of fatal and non-fatal cardiovascular events among the otherwise healthy general population. The investigators further showed that in patients who have undergone primary percutaneous coronary intervention for acute myocardial infarction, OSA was an independent predictor of future adverse event rates. Despite the observed association between OSA and adverse cardiovascular outcomes, the underlying pathophysiological mechanisms remain unclear. In this proposal, the investigators aim to elucidate the relationship between OSA and composition of coronary atherosclerotic plaques.
