Among CPCs, CD34+cells (CD34+CPCs) seem to predict outcome in CV disease, also in elderly people. A decline in CD34+CPCs was reported with advancing age. Moreover, aging is associated with a state of chronic inflammation, influencing life expectancy. Our purpose was to investigate a 10-year predictive ability of CD34+CPCs, inflammatory marker levels, classic CV risk factors (CVRFs), and Framingham Risk Score (FRS) in a population of healthy, self-sufficient octogenarians. We found that baseline CD34+CPCs was strongly associated with mortality, showing a significant difference in CD34+CPC numbers between deceased and living patients. Moreover, by dividing our patients into tertiles based on age reached, this difference was more remarkable the higher the age reached. Regressive analyses suggested that the chances of reaching an older age depend on higher CD34+CPCs at baseline and are not significantly affected by inflammatory markers levels, FRS, CVFRs, or HDL-C levels.
