The molecular mosaic of regulated cell death in the cardiovascular system

Cell death is now understood to be a highly regulated process that contributes to normal development and tissue homeostasis, alongside its role in the etiology of various pathological conditions. Through detailed molecular analysis, we have come to know that all cells do not always die in the same way, and that there are at least 7 processes involved, including: apoptosis, mitochondrial permeability transition (MPT)-driven necrosis, necroptosis, ferroptosis, pyroptosis, parthanatos, and autophagy-mediated cell death. These processes act as pieces in the mosaic of cardiomyocyte cell death, which come together depending on context and stimulus. This review details each individual process, as well as highlights how they come together to produce various cardiac pathologies. By knowing how the pieces go together we can aim towards the development of efficacious therapeutics, which will enable us to prevent cardiomyocyte loss in the face of stress, both reducing mortality and improving quality of life. •Cell death is a regulated process that contributes to development, tissue homeostasis, and various pathological conditions.•There are at least 7 forms of cell death that have been implicated in cardiovascular pathology.•These include: apoptosis, MPT-driven necrosis, necroptosis, ferroptosis, pyroptosis, parthanatos, and autophagy-mediated.•This review details these processes and highlights how they come together to produce cardiac pathologies.
