N2 - OBJECTIVES: We sought to investigate whether early and late outcome after percutaneous transluminal coronary angioplasty (PTCA) could be predicted by baseline levels of acute-phase reactants. BACKGROUND: Although some risk factors for acute complications and restenosis have been identified, an accurate preprocedural risk stratification of patients undergoing PTCA is still lacking. METHODS: Levels of C-reactive protein (CRP), serum amyloid A protein (SAA) and fibrinogen were measured in 52 stable angina and 69 unstable angina patients undergoing single vessel PTCA. RESULTS: Tertiles of CRP levels (relative risk [RR] = 12.2, p <0.001), systemic hypertension (RR = 4.3, p = 0.046) and female gender (RR = 4.1, p = 0.033) were the only independent predictors of early adverse events. Intraprocedural and in- hospital complications were observed in 22% of 69 patients with high serum levels (>0.3 mg/dl) of CRP and in none of 52 patients with normal CRP levels (p <0.001). Tertiles of CRP levels (RR = 6.2, p = 0.001), SAA levels (RR = 6.0, p = 0.011), residual stenosis (RR = 3.2, p = 0.007) and acute gain (RR = 0.3, p = 0.01) were the only independent predictors of clinical restenosis. At one-year follow-up, clinical restenosis developed in 63% of patients with high CRP levels and in 27% of those with normal CRP levels (p <0.001). CONCLUSIONS: Preprocedural CRP level, an easily measurable marker of acute phase response, is a powerful predictor of both early and late outcome in patients undergoing single vessel PTCA, suggesting that early complications and clinical restenosis are markedly influenced by the preprocedural degree of inflammatory cell activation.
