Macrophage metabolic reprogramming: A trigger for cardiac damage in autoimmune diseases

Macrophage metabolic reprogramming has a central role in the progression of autoimmune and auto-inflammatory diseases. The heart is a major target organ in many autoimmune conditions and can sustain functional and structural impairments, potentially leading to irreversible cardiac damage. There is mounting clinical evidence pointing to a link between autoimmune disease and cardiac damage. However, this association remains poorly understood, and numerous patients do not receive appropriate preventive measures, which poses serious cardiovascular risks and significantly impacts their quality of life. This review discusses the relationship between macrophage metabolic reprogramming and cardiac damage in patients with autoimmune diseases and the role of adaptive immunity in macrophage reprogramming. It also provides an overview of the immunosuppressive therapies used at present. Exploiting the properties of macrophage reprogramming could lead to development of novel treatments for patients with autoimmune-related cardiac damage.
