Who could benefit from this research

Could help

Adults in sub-Saharan Africa who have survived a previous stroke and are candidates for secondary prevention therapy.

Less likely to help

Patients with contraindications to cilostazol or a high bleeding risk may not benefit.

What this research studies

This project aims to see if cilostazol, taken twice daily with aspirin or clopidogrel, reduces recurrent stroke and heart-related problems in stroke survivors in Africa. It uses a hybrid design to evaluate safety and effectiveness in a resource-limited setting while building local stroke research capacity. The study focuses on real-world use among adults in sub-Saharan Africa who have already had a stroke, with follow-up to monitor outcomes and safety. If successful, it could provide a cost-effective option that improves long-term survival for a population with high stroke burden.

Why it matters

Potential benefit: If successful, patients could have a safer, more effective option to prevent a second stroke and related complications, potentially improving long-term survival.

How similar studies have gone: Previous data in Asian populations suggest cilostazol reduces major cardiovascular events when added to standard therapy.
