TL;DR: Coexistent mild to moderate SDB in patients with AMI increased the mobilization, proliferative and Angiogenic capacities of EPCs, angiogenic T-cell numbers, and vascular endothelial growth factor expression in monocytes compared with patients withAMI without SDB.
Abstract: Rationale: Mobilization and functions of endothelial progenitor cells (EPCs) are increased in patients with acute myocardial infarction (AMI). Yet, sleep-disordered breathing (SDB) is highly prevalent in patients with AMI.Objectives: To compare EPC numbers and functions in patients with AMI with SDB (AMI-SDB) and without SDB (AMI-only) and to determine the effects of intermittent hypoxia (IH) in vitro on EPC proliferative and angiogenic properties.Methods: Forty male patients with AMI underwent a whole-night sleep study using ambulatory monitoring. Nineteen had SDB (oxygen desaturation index > 5 events/h). AMI-SDB and AMI-only patients were matched by age, body mass index, blood chemistry, and comorbidities. Blood samples were analyzed by flow cytometry, endothelial cell colony-forming units (EC-CFU), paracrine measures, blood chemistry, and oxidative stress, inflammatory, and angiogenic markers. Effects of IH in vitro were studied in 12 healthy subjects.Measurements and Main Results: Circulating EPCs (CD...
