Abstract


The aim of this study was to assess the effect of acute and programmed physical exercise on plasma VEGF levels in chronicstable coronary artery disease patients. Following baseline evaluation, 21 patients <75 years underwent a stress myocardialperfusion scan (acute), and were then randomly assigned to perform programmed rehabilitation exercise or continue withtheir normal therapy. VEGF assessed by SPECT imaging significantly decreased after stress ergometry (from 49.59±6.06 to31.83±5.62 pg/ml; p=0.021). At one month, it increased (70.90±14.44 pg/ml) though not significantly with respect to baselinevalues (p=0.1) and significantly with respect to immediate post-stress values (p<0.01). No significant changes were observedin VEGF at 3 months or when results were compared according to the presence of ischemia or programmed exercise.Acute exercise induced a significant reduction in VEGF values, without differences between programmed exercise and thecontrol group.
