ABSTRACT
<p><b>OBJECTIVE</b>To assess the value of renal vein renin , plasma endothelin (ET), nitric oxide (NO), calcitonin gene-related peptide (CGRP) in predicting the therapeutic effect of percutaneous renal artery stenting.</p><p><b>METHODS</b>Selective renal angiography was performed in 60 patients with coronary artery disease and hypertension. All the patients with obvious unilateral renal artery stenosis (lumen narrowing >or =50%) underwent percutaneous transluminal renal angioplasty and stenting. Bilateral renal vein and inferior vena cava plasma renin activity (PRA) and plasma ET, NO, and CGRP levels were measured and the two-year follow-up data of the patients analyzed.</p><p><b>RESULTS</b>In all the patients, PRA in the ischemic kidney was significantly higher than that in the contralateral kidney (3.89-/+3.14 vs 2.01-/+1.93 nmol/L/h, P>0.05). After renal artery revascularization with stenting, PRA in the ischemic kidney was reduced obviously (P<0.05), which was significantly lower in patients with renal vein renin ratio (RVRR)>1.5 than in those with RVRR <1.5 (1.92-/+2.15 vs 2.42-/+0.56 nmol/L/h, P<0.05]. Plasma ET level was significantly higher, whereas plasma NO level significantly lower in patients with PVRR>1.5 (P<0.05). Greater improvement of blood pressure was observed in patients with RVRR>1.5 after two years than in those with RVRR< 1.5 (P<0.05).</p><p><b>CONCLUSION</b>The activity of penal vein renin, plasma ET, NO, and CGRP may provide valuable information for predicting the therapeutic effect of percutaneous renal artery stenting.</p>
