L'etude clinique du mois. L'etude HOPE, un essai clinique bicephale aux resultats contrastes.

The results of the HOPE ("Heart Outcomes Prevention Evaluation") study, recently published in the New England Journal of Medicine, demonstrated a highly significant cardiovascular protection by an angiotensin converting enzyme inhibitor, ramipril at a dose of 10 mg/day, after a mean follow-up of 4.5 years, but not of vitamin E supplements at a dose of 400 UI/day in high-risk patients (> 55 years old) who had evidence of vascular disease (secondary prevention) or combined diabetes mellitus and another cardiovascular risk factor (primary prevention).
