Patients at high risk for recurrent stroke benefit from combination therapies like aspirin with extended-release dipyridamole or clopidogrel. The PRoFESS trial investigates these and renin-angiotensin system blockers for secondary stroke prevention.
Area of Science:
- Neurology
- Cardiology
- Clinical Trials
Background:
- Patients with transient ischemic attack (TIA) and ischemic stroke face significant risks of recurrent events and mortality.
- Aspirin is a standard therapy, but recent evidence suggests combination treatments may offer superior protection.
- Renin-angiotensin system inhibitors are also being explored for their potential to reduce stroke recurrence.
Purpose of the Study:
- To compare the efficacy of extended-release dipyridamole plus aspirin versus clopidogrel in preventing recurrent strokes.
- To evaluate the added benefit of telmisartan to usual care in post-stroke patients.
- To assess the safety profiles of the investigated treatment strategies.
Main Methods:
- The Prevention Regimen for Effectively Avoiding Second Strokes (PRoFESS) trial is a large, multicenter, randomized, double-blind study.
- Over 20,000 patients were enrolled across 695 sites in 35 countries.
- A 2x2 factorial design was employed to simultaneously assess multiple treatment arms, with recurrent stroke as the primary outcome.
Main Results:
- The study aimed to determine if specific combination therapies significantly reduce the risk of recurrent stroke compared to other standard or investigational treatments.
- Safety outcomes, including major hemorrhage and other serious adverse events, were rigorously monitored.
- The PRoFESS trial represents a landmark effort in stroke prevention research due to its scale and design.
Conclusions:
- Findings from the PRoFESS trial are expected to inform clinical guidelines for secondary stroke prevention.
- The study will provide crucial data on the comparative effectiveness and safety of different antiplatelet and antihypertensive strategies.
- This research is vital for optimizing patient care and reducing the burden of recurrent strokes.

Preload refers to the degree of stretch on the heart before it contracts. It's analogous to the stretching of a rubber band; the more it's stretched, the more forcefully it snaps back. This concept is encapsulated in the Frank-Starling law of the...
