La Lettre du Cardiologue - n° 409 - novembre 2007
Le pontage a été longtemps considéré comme un meilleur mode
de revascularisation chez le diabétique que l’angioplastie. Depuis
l’introduction des stents, cette notion paraît avoir disparu, les
études se poursuivant vis-à-vis des stents actifs (36). Il reste que
les diabétiques ont une propension plus marquée à la resténose
et à la nécessité de la revascularisation. En phase aiguë, l’an-
gioplastie apparaît plus effi cace que la thrombolyse et les stents
actifs sont recommandés (37). En fait, faute d’études spécifi ques
sur le diabète et compte tenu de l’évolutivité de la maladie méta-
bolique et vasculaire ainsi que des techniques, les rédacteurs
du consensus restent prudents.
INSUFFISANCE CARDIAQUE, ARYTHMIE, MORT
SUBITE, AVC, ARTÉRIOPATHIE OBLITÉRANTE
Les recommandations n’introduisent pas de notions nouvelles,
confi rmant le rôle positif des inhibiteurs du SRA, des bêtablo-
quants, des antialdostérones, le risque accru de mort subite,
le rôle pathogène de la dysautonomie cardiaque et l’intérêt de
l’aspirine en prévention des AVC.
CONCLUSION
Ces nouvelles recommandations, sur un socle documenté, conju-
guent l’expertise des deux sociétés et permettent au cardiologue
et au diabétologue de percevoir l’unicité de la maladie chronique,
vasculaire et métabolique, et d’orienter la prise en charge quel
que soit le mode de présentation d’un patient. Dès le stade de
l’intolérance au glucose, le pronostic à long terme est en jeu,
alors que les mesures concrètes de classifi cation du risque et
de mise en œuvre des mesures préventives off rent le meilleur
rapport coût/effi cacité. ■
