KDR and congestive heart failure: Recent evidence suggests that the number of circulating proangiogenic CD14+CD309+ and CD14+CD309+Tie+2 MPCs is decreased in patients with compensated CHF, however, a linear relation between the number of these cells and SUA level has yet to be investigated.14 the objective of this study was to evaluate such a relationship between SUA and the number of proangiogenic population of MPCs in the peripheral blood of the patients with ischemic CHF.
