we assessed the association between baseline eosinophil cationic protein (ECP) levels, a sensitive marker of eosinophil activation, and clinical outcome in patients undergoing bare metal stent (BMS) implantation. METHODS: basal ECP levels were measured in 110 patients (69±11 years, 88 men) undergoing BMS implantation. Major adverse cardiac events (MACEs), defined as cardiac death, non-fatal myocardial infarction, or clinically-driven target lesion revascularization, were registered at 24-month follow-up. RESULTS: eighteen (16.4%) patients had MACEs and showed higher ECP levels compared with those without MACEs [20.1 (9.8-47.3) vs. 9.5 (5.0-27.2) g/L, p=0.02]. At follow-up, ECP level>11 g/L was the only significant predictor of MACEs (HR 3.5, 95% CI 1.1-10.4, p=0.03). CONCLUSION: basal ECP levels are associated with MACEs after BMS implantation, suggesting that an allergic-mediated inflammation against the metal could explain some adverse reactions occurring after coronary stenting.

Abstract
we assessed the association between baseline eosinophil cationic protein (ECP) levels, a sensitive marker of eosinophil activation, and clinical outcome in patients undergoing bare metal stent (BMS) implantation. METHODS: basal ECP levels were measured in 110 patients (69±11 years, 88 men) undergoing BMS implantation. Major adverse cardiac events (MACEs), defined as cardiac death, non-fatal myocardial infarction, or clinically-driven target lesion revascularization, were registered at 24-month follow-up. RESULTS: eighteen (16.4%) patients had MACEs and showed higher ECP levels compared with those without MACEs [20.1 (9.8-47.3) vs. 9.5 (5.0-27.2) g/L, p=0.02]. At follow-up, ECP level>11 g/L was the only significant predictor of MACEs (HR 3.5, 95% CI 1.1-10.4, p=0.03). CONCLUSION: basal ECP levels are associated with MACEs after BMS implantation, suggesting that an allergic-mediated inflammation against the metal could explain some adverse reactions occurring after coronary stenting.
