Background: Elevated neutrophil to leukocyte ratio in patients with ST-segment elevation myocardial infarction (STEMI) is associated with adverse clinical outcomes. However, whether decreased eosinophil ratio after primary percutaneous coronary intervention (PCI) reflects larger infarct size has not been fully investigated. This study examined the relationship between eosinophil ratio and creatinine kinase-MB (CK-MB) elevation after primary PCI in patients presenting with STEMI. Methods and Results: We analyzed the data of 321 consecutive patients who underwent primary PCI for ST-elevation myocardial infarction between January 2009 and August 2015. Total and each type of leukocyte counts 24 hours after admission were measured. The eosinophil/leukocyte ratio (ER) was calculated as the ratio of eosinophil to leukocyte count. The primary end point was major adverse cardiac event (MACE) and the follow-up period was 180 days. The mean ER and max CK-MB was 0.44±0.65 % and 217.3±224.4 IU/l, respectively. ER obtained 24 hours after admission was inversely correlated with CK-MB concentration (r=-0.37, r2=0.14, P<0.001). MACE within 180 days occurred in 68 patients (21%) including death (9%), myocardial infarction (MI) (1%) and target lesion or vessel revascularization (10%). Patients who had MACE within 180 days had lower ER (0.20±0.51 vs 0.49±0.66, P<0.001) at 24 hours after admission. Conclusions: The decreased ER after primary PCI in patients presenting with STEMI was associated with increased CK-MB concentration, which might indicate larger infarct size, therefore, poor prognosis.
