Title: Eosinophil cationic protein: A new diagnostic biomarker in coronary slow flow phenomenon

Abstract: AIM: This study has investigated the role of eosinophil cationic protein (ECP), released by eosinophils, in the coronary slow flow phenomenon.
METHODS: This study included sixty patients with coronary slow flow (CSF) and sixty patients with normal coronary flow. The coronary flow rate was evaluated with TIMI frame count (TFC). ECP level, blood count and biochemical parameters were assessed.
RESULTS: The ECP levels (18.9±7.5 vs 13.1±6.4 ng/ml, p<0.001) and eosinophil counts (0.25±0.14 vs 0.18±0.09 10³/mm³, p=0.001) were higher in the CSF group. Multivariable regression analysis showed that ECP level and eosinophil counts were independent predictors the presence of CSF (p=0.003 and p=0.006). There was a weak but important correlation among the ECP level, eosinophil count and mean TFC (p=0.001, p=0.003, respectively). The ROC analysis showed a cut off value of 14.05 ng/ml for ECP level to diagnose CSF with 73.3 % sensitivity and 66.7 % specificity, and area under the ROC curve was 0.745 (95% CI: 0.657–0.833, p<0.001).
CONCLUSION: ECP levels were increased in CSF patients and this increasing correlated with coronary artery flow rates. The ECP level was independent predictor for the presence of SCF and it may be use as suitable diagnostic biomarker for CSF (Tab. 3, Fig. 3, Ref. 30).
