Eosinophil infiltration in the heart with free-wall rupture following acute myocardial infarction: a case report

A 90-year-old woman was referred to us due to acute extensive anterior myocardial infarction with cardiogenic shock. Echocardiography revealed akinesis of infarct region, associated with wall thinning. She was treated with catecholamines and diuretics because her hemodynamics were classified in Forrester subset IV. On the ninth day after the onset of infarction, she died of free-wall rupture. The postmortem histological study demonstrated eosinophil infiltration in the area of rupture, which may have been a pathological factor.
