Abstract
Previous studies have suggested that physical exercise may have an effect on the turnover of the endothelial compartment. Following a maximal exercise testing (Bruce protocol), a prompt and significant increase in the number of circulating endothelial cells (CECs) was detected (Δ 1 50% vs. basal; P = 0.0001) in 12 healthy volunteers, without significant changes in the marker of myocardial ischemia; the frequency of CECs correlated significantly with systolic blood pressure (SBP) and rate-pressure product at peak exercise (r = 0.78, P = 0.003, and r = 0.64, P = 0.03, respectively). These results support the role of peak SBP during maximal exercise possibly as mechanical factor facilitating the detachment of CECs and the endothelial turnover.File | Dimensione | Formato | |
