  • Title: Endothelial dysfunction in chronic heart failure: some new basic mechanisms.
    Author: Bachetti T.
    Journal: Ital Heart J; 2000 Oct; 1(10):656-61. PubMed ID: 11061361.
    Abstract:
    Endothelial dysfunction contributes to the maintenance of peripheral vasoconstriction and abnormal vascular compliance in chronic heart failure. Endothelial dysfunction results in an imbalance between vasodilation and vasoconstriction, particularly when adjustments in blood flow are required. Recently, new factors have been recognized to determine endothelial dysfunction: a) disturbances of the L-arginine/nitric oxide pathway, either at the enzymatic or substrate level; b) increased synthesis of endothelin-1; c) microvessel structural remodeling; d) increased adhesive properties to blood cell components; and e) apoptotic cell injury. The understanding of the complex interplay among these factors is the basis for development of new targeted strategies to correct endothelial dysfunction in chronic heart failure.
