Therapeutics

Combined treatment with indapamide and perindopril but not perindopril alone reduced the risk for recurrent stroke

PROGRESS Collaborative Group. Randomised trial of a perindopril-based blood-pressure-lowering regimen among 6105 individuals with previous stroke or transient ischaemic attack. Lancet 2001 Sep 29;358:1033–41[Medline]

QUESTION: In patients with a history of stroke or transient ischaemic attack (TIA), is perindopril alone or combined with indapamide more effective than placebo for reducing fatal or non-fatal stroke?

Design
Two* randomised (allocation concealed{dagger}), blinded {patients, clinicians, data collectors, outcome assessors, data analysts, and manuscript writers}{ddagger},{dagger} 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).

Main outcome measures
