PURPOSE: To investigate the prognostic value of elevated C-reactive protein levels in patients with stable angina who underwent coronary stenting. METHODS: We followed a consecutive series of 1152 patients with stable angina who had undergone coronary stenting. We measured baseline C-reactive protein levels before stenting with a high-sensitivity assay; 651 patients (57%) had elevated C-reactive protein levels (>5 mg/L). The primary endpoint was either death or myocardial infarction within 1 year after the procedure. Angiographic restenosis was defined as a > or =50% diameter stenosis at follow-up angiography. RESULTS: During the 1-year follow-up, 62 (9.5%) of the 651 patients with an elevated C-reactive protein level and 24 (4.8%) of the 501 patients with normal levels died or had a myocardial infarction (P = 0.002). In a multivariate analysis, elevated baseline C-reactive protein levels were associated with almost a twofold increase in the rate of death or myocardial infarction after coronary stenting (hazard ratio = 1.8; 95% confidence interval: 1.1 to 2.9). Most of the difference in the event rates developed within the first 30 days. Baseline C-reactive protein levels did not correlate with restenosis. CONCLUSION: Elevated preprocedural C-reactive protein levels are associated with a less favorable prognosis in patients with stable angina who undergo coronary stenting. The measurement of C-reactive protein levels in these patients may help to identify those who may benefit from a treatment strategy aimed at the attenuation of inflammation.
