Dilated cardiomyopathy (DCM) is one of the common primary diseases of heart failure and arrhythmias. With the continuous deepening of research in recent years, the intrinsic molecular mechanism of regulatory cell death (RCD) has gradually become clear. Researchers have found that RCD plays a very important role in the occurrence and development of DCM. RCD mainly includes apoptosis, necrotic apoptosis, Pyroptosis, Ferroptosis, autophagy, etc. They have certain correlation and can interact and regulate each other. This article provides an overview of the current research status on the mechanisms of the five RCD modes involved in DCM, in order to provide reference for future related experiments and clinical studies.
