Myeloid cells take ischemic insult to heart

Morbidity and mortality associated with stroke cannot be attributed solely to the acute ischemic event, but are also rooted in long-term complications, including heart disease. Simats, Zhang, and colleagues now demonstrate that interleukin (IL)-1ß-mediated innate immune memory after brain ischemic stroke leads to proinflammatory changes in the heart causing myocardial fibrosis.
