Summary: | To assess the value of serial C-reactive protein (CRP), serum amyloid A (SAA), tumor necrosis factor-alpha (TNF-alpha) and interleukin-10 (IL-10) evaluation in the risk stratification in patients undergoing percutaneous coronary intervention. The study was designed as a prospective cohort trial with a 1-year follow-up. Eighty patients (70 with stable angina, 10 with unstable angina) were enrolled. Blood samples were collected before the procedure and after 6 and 24 h, and 1 month. Clinical follow-up visits were performed (*with exercise test) 7 days* and 1*, 3, 6* and 12 months after the procedure. Any symptoms of restenosis were verified angiographically. Multivariate logistic regression analysis identified increased preprocedural TNF-alpha and CRP levels and elevated CRP concentrations evaluated 24 h after the procedure as significant predictors of both clinical restenosis and major adverse cardiac events (MACE), while high SAA values at 24 h accurately predicted clinical restenosis. Patients, who were in the highest tertile of, either, baseline TNF-alpha and/or baseline CRP/CRP at 24 h, were more prone to develop restenosis and MACE than stratified only on the basis of a single marker. Our data indicate that combined analysis of CRP and TNF-alpha might be an effective approach to the clinical restenosis and MACE prediction. Additionally, long-term outcome is markedly influenced by the periprocedural activation of inflammation. |
