Abstract

Background and purpose: The association of circulating endothelial progenitor cells (EPCs) with different cardiovascular diseases and their related major adverse cardiovascular events (MACE) remained inconclusive. We aimed to clarify associations between the circulating EPC levels and the risk of MACE concerning different atherosclerosis-related diseases. Methods: This prospective cohort study was conducted from December 2009 to March 2015. Patients who underwent non-emergent coronary angiography (CAG) were included. The circulating EPC levels were measured using flow cytometry prior to the CAG procedure. The study evaluation of circulating EPC levels among patients with obstructive coronary artery disease (CAD) and other comorbidities. Patients were then assigned to tertiles by circulating EPC levels to evaluate the predictive values of the development of MACEs. Results: The study enrolled 1099 patients, of whom, 736 (67%) were men, with a mean age of 66.7 ± 12.5 years old. Overall, 637 (58%) patients were diagnosed with obstructive CAD according to CAG. MACE occurred in 268 (24.4%) patients. Circulating EPC levels were lower in patients with peripheral artery disease (PAD) but not associated with the presence of obstructive CAD, atrial fibrillation, chronic kidney disease (CKD), heart failure, and diabetes mellitus. Higher circulating EPC levels are linked with higher MACE among patients with suspected CAD, regardless of the presence or absence of obstructive CAD or CKD. The association did not present in patients with PAD. Conclusions: Higher circulating EPC levels are associated with a greater risk of MACE, regardless of the presence of obstructive CAD or CKD. This association was not apparent in the patients with PAD, suggesting impaired endothelial repair in these patients.
