Study of Role of Blood Microvescicles and Exosomes in Patients With Graft Occlusion After Aortocoronary Bypass Surgery

Sponsor: Maria Cecilia Hospital

Summary

Coronary artery bypass graft (CABG) surgery is still the standard treatment of coronary revascularization for patients with severe coronary artery disease (CAD). Graft patency, together with completeness of revascularization, is a major determinant of long-term outcome following CABG. The surgical procedure elicits a persistent systemic inflammatory response associated with the activation of the hemostatic system leading to perturbation of endothelial and vascular function and activation of platelets and leukocytes. All of these events are the main players responsible for the early and late graft failure in a significant percentage of patients.
