Antiplatelet therapy is an integral component of effective secondary prevention after non-cardioembolic ischemic stroke. Numerous clinical trials have tested the efficacy and safety of different antiplatelet regimens, including aspirin monotherapy, clopidogrel monotherapy, the combination of aspirin plus clopidogrel, and the combination of aspirin plus dipyridamole, in patients with a history of arterial ischemic stroke and transient ischemic attack (TIA). Although competing, head-to-head comparisons between aspirin plus dipyridamole and clopidogrel were not previously available, various professional societies have outlined evidence-based recommendations for antiplatelet therapy in patients with ischemic stroke or TIA. ⋯ The results of PRoFESS thus highlight the pitfalls of making conclusions of relative therapy efficacy in the absence of head-to-head comparisons. This article presents an overview of the factors that differ between clinical trials and "real-world" patient populations, as well as factors that differ among clinical trials themselves. The article also addresses the potential impact these differences may have on clinical trial results and subsequent clinical decision making.
