Objective. To identify markers (phenotypic, genetic, or environmental) of blood pressure (BP) response profiles to angiotensin converting enzyme inhibitors (ACEIs) and diuretics. Methods. IDEAL was a crossover (two active and two wash out phases), double-blind, placebo-controlled trial. Eligible patients were untreated hypertensive, aged 25 to 70. After two visits, patients were randomized to one of four sequences. The main outcome was BP differences between the active treatment and placebo. Results. One hundred and twenty-four patients were randomised: mean age 53, men 65%, family history of hypertension 60%. Average BP fall at each visit before randomisation was about 2% of the initial level reflecting both a regression to the mean and a placebo effect. Conclusion. The results are expected to improve knowledge in drug’s mechanisms of action and pathophysiology of hypertension, and to help in personalizing treatment. The estimation of BP responses to each drug in standardized conditions provided a benefit to each participant.
Résumé
Objectif. Identifier les marqueurs (phénotypiques, génétiques, environnementaux) des profils de réponse pressionnelle à un inhibiteur de l’enzyme de conversion de l’angiotensine et un diurétique. Méthodes. IDEAL est un essai en plan croisé (2 phases actives et 2 phases de désimprégnation) en double-insu versus placebo. Les patients étaient des hypertendus non traités de 25 à 70 ans. Deux visites précédaient la randomisation des patients. Le critère principal était la différence de PA traitement actif versus placebo. Résultats. Cent vingt-quatre patients ont été randomisés d’âge moyen 53, hommes 65 %, histoire familiale d’hypertension 60 %. La baisse moyenne de PA à chaque visite pré-randomisation était d’environ 2 % du niveau initial traduisant une régression vers la moyenne et un effet placebo. Conclusion. IDEAL permettra d’améliorer les connaissances sur les mécanismes d’action des médicaments dans l’hypertension, étape indispensable vers la personnalisation du traitement. L’estimation de la réponse pressionnelle dans des conditions standardisées a représenté un bénéfice réel pour chaque participant.
