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.
