Description du projet
La vitamine K peut-elle prévenir l’athérosclérose?
Les maladies cardiovasculaires sont associées à la formation de plaques d’athérome sur les parois des vaisseaux, qui peuvent se rompre et entraîner de graves complications, voire la mort. De nouvelles données indiquent un risque plus élevé de crises cardiaques et d’accidents vasculaires cérébraux chez les personnes dont les plaques présentent des dépôts de calcium (microcalcifications). Financé par le programme Actions Marie Skłodowska-Curie, le projet INTRICARE vise à étudier les causes de la microcalcification et la manière dont elle affecte la stabilité de la plaque. Les traitements et les méthodes de prévention actuels étant insuffisants, le consortium propose d’utiliser la supplémentation en vitamine K comme stratégie pour prévenir ou améliorer la formation de la plaque vulnérable.
Objectif
Cardiovascular disease remains one of the major challenges of contemporary society, being responsible for a staggering 47% of deaths in Europe. Vascular calcification in particular requires immediate attention as it is strongly associated with increased cardiovascular mortality and morbidity, and is recognised as an important independent risk factor for cardiovascular death. Recent reports demonstrate that especially punctuated and spotty calcifications (microcalcifications) in the plaque are life-threatening. Microcalcifications are particularly prominent in the vulnerable atherosclerotic plaque that is at high risk of rupture, a cardinal event that can cause thrombosis, infarct, cardiac arrest, stroke and death. In fact, 20% of European deaths are directly attributable to thrombotic rupture of a vulnerable plaque; a clear indication that current treatments and preventive measures are insufficient. Recent findings suggest a link between vascular smooth muscle cell phenotype mediated calcification and inflammation, which could underlie the plaque destabilising effects of microcalcification. However, a comprehensive view on what causes microcalcification and its impact on plaque stability remains elusive and there is an urgent need to translate experimental findings into adequate diagnostic, preventive and therapeutic solutions. INTRICARE is shaped to address the urgent unmet medical needs concerning calcification-induced vulnerable plaques and is guided by the academic and industrial demand for a new generation of entrepreneurial scientists that have the skills, expertise and knowhow to expedite our understanding of vascular calcification and translation thereof into concrete, effective clinical solutions. The INTRICARE ESRs harbour ongoing vitamin K-supplementation trials that will be pivotal in the identification of selective biomarkers for microcalcification and subsequent development of strategies for prevention or amelioration of vulnerable plaque formation.
