Increased C-Reactive Protein Level After Renal Stent Implantation in Patients with Atherosclerotic Renal Stenosis:

Elevated C-reactive protein (CRP) level has been demonstrated in patients with coronary artery disease after coronary stent implantation, but no data are available in patients with atherosclerotic renal artery stenosis concerning whether such changes of CRP also exist after renal artery stent implantation. The authors hypothesize that elevated CRP level may also be present in patients with atherosclerotic renal artery stenosis after stent implantation owing to mechanical disruption of atherosclerotic plaque. In total, 24 patients were enrolled in this study. Of these, 14 patients with atherosclerotic renal artery stenosis received renal angioplasty plus stent implantation (group A, mean age 51 ±8 years), and 14 age- and gender-matched patients underwent renal angiography for diagnostic purpose as a control group (group B, mean age 50 ±8 years). Peripheral blood samples were taken before the procedure and at 6 and 24 hours after the procedure in both groups. Plasma CRP concentration was measured by using i...
