Impact of depression on circulating endothelial progenitor cells in patients with acute coronary syndromes: a pilot study.

Aims: Depression has been identified as a risk factor for an adverse prognosis and reduced survival in patients with acute coronary syndrome (ACS). The number of endothelial progenitor cells (EPCs) is an independent predictor of clinical outcomes in patients with ACS. The aim of this study was to evaluate the impact of depression on EPC levels in patients with ACS.
