If the blood-pressure target had not been achieved with the highest tolerated dosage of ramipril, additional drugs had been added, including furosemide, beta-blockers, calcium-channel blockers, acting alpha-adrenergic blockers centrally, and direct vasodilators. In the very beginning of the cohort phase, the blood-pressure focus on was less than 140/90 mm Hg.
