Özet
Objective: To investigate the relation between serum high sensitivity (hs) C reactive protein (CRP), proinflammatory cytokine concentrations, proinflammatory to anti-inflammatory cytokine ratios and long-term prognosis in patients with non-ST elevation acute coronary syndrome (NSTEACS). Design: Prospective follow-up study for the first six months and then for the first year after admission to hospital. Setting: Tertiary referral centre. Patients: 80 patients (60 men, 20 women, mean age 60 (SD 10) years) with NSTEACS and moderate to high TIMI (Thrombolysis In Myocardial Infarction) risk scores. Interventions: Blood samples from patients with NSTEACS were obtained at the time of admission. Serum concentrations of hs-CRP, (hs) pro-inflammatory (interleukin (IL)-1 beta, IL-6, tumour necrosis factor a) and ( hs) anti-inflammatory (IL-10) cytokines were analysed and proinflammatory to anti-inflammatory cytokine ratios were calculated by dividing proinflammatory cytokine concentrations by anti-inflammatory cytokine IL-10. Main outcome measure: The primary end point of the study was new coronary events (NCE) defined as the combination of cardiac death, non-fatal myocardial infarction and recurrent rest angina that required hospitalisation within 12 months of follow up. Results: During the one-year follow-up period, 23 patients (29%) met the NCE criteria. Concentrations of hs-CRP, IL-1 beta and IL-6 and ratios of IL-1b: IL-10 and IL-6: IL-10 were significantly higher in patients with NCE than in patients without NCE. In the logistic regression analysis, IL- 6: IL- 10 ratio was the most important predictor for NCE (p = 0.006) with an odds ratio of 2.24 (95% CI 1.26 to 3.97). Conclusions: Cytokine concentrations and proinflammatory to anti-inflammatory cytokine ratios may be useful markers for predicting vascular risk in patients with NSTEACS.
