La cigarette électronique aussi nocive que le tabac pour le cœur

La cigarette électronique est souvent présentée comme un substitut possible et sans danger au tabac car elle ne contient pas de goudron et de substances cancérigènes connues. Mais cette affirmation vient d'être remise en cause par une étude américaine.

Des chercheurs de la Brown University ont en effet montré, grâce à des expériences réalisées simultanément sur des cellules musculaires lisses vasculaires de rats et d’humains, que le mécanisme par lequel la nicotine agit sur ces cellules vasculaires et entraîne la formation de plaques d’athérome est impliqué dans de nombreuses maladies cardio-vasculaires.

Cette étude montre en outre que l’exposition des cellules lisses vasculaires à la nicotine augmente leur risque de détérioration. Finalement, la combinaison de ces deux facteurs provoque un risque accru de dégradation de la paroi artérielle d'apparition d’athérosclérose. Ces travaux ont également pu montrer que ces cellules, lorsqu'elles sont soumises à des substances inhibant l’action de la nicotine, ne sont plus exposées à ce mécanisme qui les détériore, ce qui démontre le rôle clé de la nicotine dans ce processus.

Le professeur Hai, qui a dirigé ces recherches, précise que ses travaux montrent pour la première fois de manière solide que la substitution de la cigarette électronique à la cigarette classique ne diminue pas le risque d'athérosclérose. Ce scientifique souligne néanmoins qu'il va falloir à présent essayer de mieux comprendre ces mécanismes de synergie entre le récepteur nicotinique de l'acétylcholine et la Protéine kinase C dans l'altération des cellules lisses vasculaires pour concevoir de nouveaux traitements capables de réduire les effets néfastes intrinsèques de la nicotine sur le système cardio-vasculaire.

    J'aimerai bien connaitre la véracité de cette étude...
    Il y a de plus en plus de tabacologue qui sont favorable à la cigarette électronique, et vont même jusqu'à la prescrire à leurs patients comme on peut le voir sur un article présent sur le blog du site Top Cigarette Electronique.
    Et les Américains sortent une étude pour montrer le contraire... Sachant que les Américains ont légalisés le Cannabis dans certains états pour remplir les caisses, comme ils le disent eux mêmes! Donc qui croire? La réponse est toute trouvé pour moi, qui a réussi à arrêter de fumer, et je me porte beaucoup mieux!

    Cette étude précise l'effet délétère de la nicotine sur les vaisseaux sanguins. Il ne s'agit nullement d'une condamnation de la cigarette électronique mais de la nicotine, qu'elle soit absorbée par la cigarette, la cigarette électronique ou même le patch délivré en pharmacie !
    C'est le titre de l'article qui est inadapté et il faudrait le changer au regard des 72000 personnes qui meurent en France tous les ans à cause du tabac !
    Par ailleurs il existe des produits à utiliser avec la cigarette électronique qui ne contiennent pas de nicotine.

    Le titre "La cigarette électronique aussi nocive que le tabac pour le cœur " de cette information est totalement inadapté. Il l'est tellement que cela révèle la nature du but recherché.
    Pas de commentaire supplémentaire, tout est dit !
    ( Pour les septiques ... Dénigrer le produit concurrent en prouvant qu'il n'est pas moins nocif ... ça limite la vague de développement des e-cigarettes tous azimuts, et donc ça donne du temps aux bureaux d'études de fabriquer les produits Philipp Morris et autres géants du secteur pour ré-inonder ce nouveau marché ! In gold we trust !)
