Chronic Kidney Disease
Conditions
Brief summary
The primary objective is to determine whether reduction of serum calcium concentration by cinacalcet leads to reduction of mean blood pressure adjusted c-fPWV. The secondary objectives are to study the effects of calcium reduction on 1) carotid-radial PWV (c-rPWV), 2) common carotid artery (CCA) biomechanics, 3) pulse wave profile and cardiac function.
Interventions
One sequence receives Cinacalcet 30mg /d for 7 days followed by placebo for 7 days
