  • Title: [Is there an indication for the association of betablockers and angiotensin II receptor antagonists in cardiac failure?].
    Author: Jondeau G, Milleron O, Morisson-Castagnet JF.

    Abstract:
    ACE inhibitors initially developed as vasodilators are effective by their anti-hormonal action. Antagonists of the receptors of angiotensin II (ARA II) should provide an equivalent or better blockade of the rennin-angiotensin system (absence of tolerance). Clinical trials have shown equivalent haemodynamic effects of the two classes, equal functional tolerance but mortality studies have shown more variable results. None have shown the superiority of ARA II over ACE inhibitors and the demonstration of their equivalence has just been reported with high doses in the post-infarction period. A deleterious effect of ARA II in association with betablockers was reported in two mortality studies but has not been confirmed in the most recent trials. The difficulty is to determine the roles of the association of ARA II-ACE inhibitors, ARA II-antialdosterones or of the association of all three classes of molecules.
