Le c\u0153ur n’est pas seulement une pompe m\u00e9canique, mais un organe extr\u00eamement complexe dont les performances d\u00e9pendent en grande partie de r\u00e9seaux de signalisation intracellulaires finement ajust\u00e9s dans les cardiomyocytes. Ces voies de signalisation r\u00e9gulent sans cesse des processus tels que la contraction, le m\u00e9tabolisme du calcium et de l’\u00e9nergie, la survie des cellules et la r\u00e9g\u00e9n\u00e9ration. Un \u00e9quilibre sain de ces r\u00e9seaux garantit que le c\u0153ur peut adapter sa capacit\u00e9 de pompage aux exigences physiques changeantes. Toutefois, si certaines voies de signalisation ne fonctionnent pas correctement, des modifications subcliniques peuvent \u00e9voluer discr\u00e8tement vers des maladies graves telles que l’insuffisance cardiaque, les arythmies ou les cardiomyopathies. <\/strong><\/p>\n\n
