Periprocedural levels of various inflammatory markers have been correlated with prognosis in patients undergoing percutaneous coronary interventions. However, long‐term variations of interleukin‐1 receptor antagonist (IL‐1Ra) or C‐reactive protein (CRP) during follow‐up after coronary interventions were not previously investigated. The aim of our study was to perform serial evaluations of these markers before and after coronary stenting and to correlate them with clinical status. Plasma levels of IL‐1Ra and CRP were measured at baseline and 3 and 6 months after the procedure in 31 patients with symptomatic coronary artery disease undergoing stent implantation, who had no evidence of myocardial ischemia at 6‐month follow‐up. While at 3 months there were no significant variations of baseline values, 6 months after the procedure a significant decrease from baseline was observed both in IL‐1Ra and CRP levels (median −24 pg/ml, P = 0.048, and −0.13 mg/dl, P = 0.017, respectively). Six‐month reduction in both IL‐1Ra and CRP levels was significant in patients with unstable angina (n = 18; IL‐1Ra: from 175 to 119 pg/ml, P = 0.001; CRP: from 0.52 to 0.18 mg/dl, P = 0.002) and nonsignificant in those with stable angina (n = 13) on admission (IL‐1Ra: from 123 to 158 pg/ml, P = 0.22; CRP: from 0.19 to 0.10 mg/dl, P = 0.44). In conclusion, a significant reduction of IL‐1Ra and CRP levels is observed 6 months after stent implantation in patients with preprocedural unstable angina who remain free of ischemia. This decrease suggests a stabilization of the inflammatory process and may be associated with a favorable prognosis after coronary interventions.
