Interpretation of these results in chronic ischemic diseases may be even more complex when considering that a previous study from our group has shown that SDF-1-induced migration of CD45(dim)CD34+CXCR4+KDR+ MNCs was higher in patients with cardiovascular death, forecasting cardiovascular mortality independently of other validated predictors, such as age, diagnosed coronary artery disease, serum C-reactive protein, and estimated glomerular filtration rate [21]. Here, CD34 is linked to coronary artery disorder.
