Heart Failure (IMAGE) Johns Hopkins Medicine Caption A modified electron microscopy image of eosinophils infiltrating a heart. Eosinophils (pink) can be seen between heart muscle cells (blue) and fibroblasts (turquoise). Eosinophils and other immune cells (orange) exit the blood vessels (green) and infiltrate the heart during myocarditis. This image was taken from a hypereosinophilic mouse with experimental autoimmune myocarditis.
