In period I (washout and single-blind): from visit 1 to visit 2, 2 weeks placebo run-in. In period II (double-blind treatment, randomized): Ramipril 5 mg for 4 weeks (visit 2 - visit 3). At visit 3, medications had to be titrated to Ramipril 10 mg only if BP remained ≥ 140/90 mmHg. Double blind treatment had to be continued for another 4-week period until visit 4. In period III (double-blind withdrawal): At visit 4, part of patients received the active treatment for 1 day. The study ended at visit 5 (48 hours later than visit 4).
