Investigating microparticles in patients with obstructive sleep apnea

Microparticles as a Biomarker of Incident Cardiovascular Risk in Patients With Obstructive Sleep Apnea

Observational University Hospital, Angers · NCT03438149

This study is testing how higher levels of certain tiny particles in the blood might affect heart health in people who have both obstructive sleep apnea and existing heart problems.

What this trial studies

This observational study aims to evaluate the impact of increased levels of leukocyte-derived microparticles (MPs) on cardiovascular outcomes in patients diagnosed with obstructive sleep apnea (OSA) who also have prevalent cardiovascular diseases. It focuses on understanding how these microparticles, which are known to be elevated in OSA, may contribute to endothelial dysfunction and other cardiovascular risks. The study will involve assessing patients with coronary artery disease or cerebrovascular disease who are also diagnosed with moderate-to-severe OSA, to determine the relationship between MP levels and cardiovascular prognosis.

Who should consider this trial

Good fit: Ideal candidates for this study are individuals diagnosed with moderate-to-severe obstructive sleep apnea and prevalent cardiovascular diseases such as coronary artery disease or cerebrovascular disease.

Not a fit: Patients who are pregnant or have previously treated obstructive sleep apnea may not receive benefit from this study.

Why it matters

Potential benefit: If successful, this study could provide insights into the cardiovascular risks associated with obstructive sleep apnea, potentially leading to improved management strategies for affected patients.

How similar studies have performed: While there is growing evidence regarding the role of microparticles in cardiovascular diseases, this specific approach focusing on OSA and its cardiovascular implications is relatively novel.
