Des chercheurs de l’Universit\u00e9 de Pennsylvanie (Etats-Unis) ont mis au point un gel injectable qui permet de pr\u00e9venir le risque d’insuffisance cardiaque apr\u00e8s un infarctus.
Apr\u00e8s un premier infarctus , un patient sur quatre souffre d’insuffisance cardiaque et un sur dix fait un deuxi\u00e8me infarctus. Pour pr\u00e9venir ce risque, les chercheurs de l’Universit\u00e9 de Pennsylvanie (Etats-Unis) ont mis au point un gel injectable \u00e0 administrer aux patients apr\u00e8s leur infarctus.
Cet hydrogel biod\u00e9gradable est compos\u00e9 d’une mol\u00e9cule de sucre naturellement pr\u00e9sente dans l’organisme dans laquelle des cellules ont \u00e9t\u00e9 inject\u00e9es. Ces cellules apportent un soutien m\u00e9canique \u00e0 la zone du c\u0153ur qui a \u00e9t\u00e9 endommag\u00e9e, permettant de limiter la formation de tissu cicatriciel.
Ce gel permet \u00e9galement de limiter les fuites de sang \u00e0 travers les valves et pr\u00e9serve la taille naturelle du c\u0153ur.
Enfin, au chapitre bonnes nouvelles, l’injection de ce gel ne n\u00e9cessite aucune op\u00e9ration \u00e0 c\u0153ur ouvert puisque la simple pose d’un catheter sur la peau suffit.
Les chercheurs am\u00e9ricains ont pr\u00e9sent\u00e9 leurs travaux lors du Congr\u00e8s annuel de l’American chemical society. Pour l’instant, les essais n’ont \u00e9t\u00e9 men\u00e9s que sur des c\u0153urs d’animaux.<\/p>\n","protected":false},"excerpt":{"rendered":"
