Brief Summary

Chronic kidney disease (CKD) is a prevalent disorder and a major health concern. Cardiovascular disease is the most prevailing and life-threatening complication observed in patients with CKD. The diagnosis of CKD places a patient at the highest cardiovascular risk level irrespective of the stage of renal decline. Therefore, fatal cardiovascular events are more likely to occur than the evolution to final stages of kidney disease with the need for dialysis. Counter intuitively, treatment of classical cardiovascular risk factors does not affect cardiovascular prognosis in CKD, which suggests that the missing link between these two entities has not been elucidated yet. In the present project, the investigators focus on endothelial dysfunction in patients with CKD. Endothelial dysfunction precedes overt atherosclerotic changes by many years. In the absence of structural changes, endothelial dysfunction is still reversible, which offers therapeutic perspectives to tackle the progression towards atherosclerosis in an early stage. The purpose of this study is to determine whether an exercise training program is effective in ameliorating endothelial dysfunction in patients with chronic kidney disease.

  3 months

• change in Intima Media Thickness (µm) of the right common carotid artery

  3 months

Other Outcomes (2)

• change in circulating endothelial progenitor cells (cells/1 million CD45+ events)

  3 months

• change in migratory function of circulating angiogenic cells

  3 months
