Aims: The acute phase reactant C-reactive protein is an important prognostic risk factor in patients with both stable and unstable coronary artery disease. The potential prognostic implications of an abnormal pre-procedural C-reactive protein concentration in patients undergoing elective coronary angioplasty may be relevant for subsequent treatment. Methods and Results: Pre-procedural plasma levels of C-reactive protein were measured in 501 patients with stable coronary artery disease undergoing elective coronary angioplasty. The incidence of death or myocardial infarction during a 2-year follow-up was 10.6% (24/227) in patients with an increased C-reactive protein level (>3 mg.l-1) and 2.9% (8/274) in patients with a normal C-reactive protein level (RR 3.9, 95% CI 1.7-8.9). Survival without death, myocardial infarction, urgent revascularization or hospital admission for unstable angina was significantly lower in patients with an increased C-reactive protein vs patients with a normal C-reactive protein (log-rank 14.62, P<0.0001). Logistic regression analysis identified an increased C-reactive protein level as a strong independent predictor of event-free survival (RR 2.54, 95% CI: 1.44-4.47, P=0.001). Conclusion: Pre-procedural C-reactive protein levels are increased in 45% of patients undergoing elective coronary angioplasty. An increased C-reactive protein level is a powerful independent prognostic indicator for subsequent cardiac events, suggesting that late clinical outcome is markedly influenced by pre-procedural systemic activation of inflammation. © 2002 The European Society of Cardiology.
