Two* randomised (allocation concealed
), blinded {patients, clinicians, data collectors, outcome assessors, data analysts, and manuscript writers}
,
placebo controlled trials with a mean follow up of 3.9 years (Perindopril Protection against Recurrent Stroke Study [PROGRESS]).
Setting
172 centres from 10 countries.
Patients
6105 patients (mean age 64 y, 70% men) who had a history of stroke or TIA in the previous 5 years, had no definite indication for or contraindication to an angiotensin-converting enzyme (ACE) inhibitor, and were clinically stable for
2 weeks after their most recent vascular event. 6102 patients (> 99%) completed follow up for fatal events.
Intervention
Some patients were allocated to perindopril 4 mg daily (n=1281) or to single placebo (n=1280). Other patients, for whom the responsible physician found no specific indication for or contraindication to a diuretic, were allocated to perindopril plus indapamide (indapamide dose 2.0 or 2.5 mg daily) (n=1770) or to double placebo (n=1774).
