D\u00c9CRYPTAGE – <\/strong>Six mois apr\u00e8s une infection, les patients ont une perte d\u2019\u00e9lasticit\u00e9 des art\u00e8res. Un processus qui augmente le risque d\u2019infarctus et d\u2019AVC.<\/p>\n

Avec le temps,\u00a0les vaisseaux sanguins<\/a>\u00a0perdent l\u2019\u00e9lasticit\u00e9 qui leur permet d\u2019amortir les variations de pression dues aux battements du c\u0153ur. Ce processus de rigidification, qui accro\u00eet les risques d\u2019infarctus, d\u2019AVC et de d\u00e9mence, est l\u2019un des effets naturels du vieillissement. Il peut \u00eatre aggrav\u00e9 par des facteurs ext\u00e9rieurs comme le tabagisme,\u00a0l\u2019hypertension<\/a>, le diab\u00e8te ou le cholest\u00e9rol\u2026 ainsi que par le Covid, comme le sugg\u00e8re une \u00e9tude internationale publi\u00e9e lundi 18\u00a0ao\u00fbt. \u00ab\u00a0On a bien vu, durant la pand\u00e9mie, que le virus Sars-CoV-2 entra\u00eene des complications vasculaires et cardiaques aigu\u00ebs, explique Rosa Maria Bruno, professeur de pharmacologie \u00e0 l\u2019universit\u00e9 Paris-Cit\u00e9, sp\u00e9cialiste de l\u2019hypertension \u00e0 l\u2019h\u00f4pital europ\u00e9en Georges-Pompidou (Paris), et premi\u00e8re auteur de la recherche. Nous avons cherch\u00e9 \u00e0 savoir s\u2019il pouvait aussi induire des effets \u00e0 long terme sur le syst\u00e8me vasculaire.\u00a0\u00bb<\/p>\n

Pour ce faire, son \u00e9quipe a utilis\u00e9 une m\u00e9thode de mesure de la perte d\u2019\u00e9lasticit\u00e9. Elle consiste\u2026<\/p>\n
