How are the necrotic myocardial cells removed

WebTypically, cells that die as a result of necrosis do not signal nearby phagocytes to ingest said dead cells, which leads to a build up of dead tissue and cell debris. Necrotic tissue can delay wound healing , and it is often necessary for the devitalized tissue to be removed before any progress towards healing can be made.
