Circulating endothelial progenitor cells increase in patients with coronary artery disease after exercise.

The aim of this study was to analyze whether a maximal stress test in patients with coronary artery disease increases the number of circulating endothelial progenitor cells (EPCs). They found that patients with symptomatic coronary artery disease respond to a single episode of exercise-induced myocardial ischemia with an increase in circulating EPCs.
