Background:
This study explored the clinical significance of CD34(+)/133(+) circulating progenitor cell (CPC) counts in patients with stable angina pectoris (AP) who underwent percutaneous coronary intervention (PCI).
Methods And Results:
Subjects comprised 52 patients with stable AP requiring PCI and 50 control patients without AP. In the AP group, blood samples were taken before and 20 min and 24 h after PCI to measure CPC counts by fluorescence-activated cell sorter analysis. The baseline number of CPCs was smaller in the AP group than in controls. In the AP group, body mass index (BMI) correlated positively with the baseline number of CPCs and was an independent predictor of CPC count in multivariate regression analysis. Other conventional risk factors, daily exercise activity and statin administration showed no association with CPC count. CPC counts remained unchanged within 24 h after PCI.
Conclusions:
CPC counts in patients with AP are influenced by BMI, but not by other coronary risk factors. CPC counts remain unchanged within 24 h after PCI.
