Résumé : Ibopamine, a drug improving diuresis and cardiac contractility, was administered to 30 geriatric patients suffering from congestive heart failure (pulmonary stasis, oedema of lower limbs). Substituted to diuretics and cardiotonics, ibopamine 100 mg/day per os increased the diuresis as well as the urinary excretion of electrolytes and improved significantly the signs and symptoms of heart failure. The increase of diuresis was particularly consistent in a group of patients classified as 'responders' (+66 %). Tolerance was good in every patient.
