Transient ischaemic attacks : new approaches to management

The fact that transient ischaemic attacks are a harbinger for the possible development of ischaemic stroke has been recognised for several decades. However, within the past decade, our concepts regarding transient ischaemic attacks as a distinct entity from stroke and the prognosis for transient ischaemic attack patients have been challenged. In addition, clinical trials have clarified that modern transient ischaemic attack management is more complex than in the past, with the addition of newer pharmacological options to the stroke prevention armamentarium. Recent information regarding newer antiplatelet agents is reviewed in this article, along with results of clinical trials pertaining to warfarin in stroke prevention. The evolving role of statins, ACE inhibitors and estrogen replacement is reviewed. Finally, the appropriate use of surgery following transient ischaemic attacks is outlined. Recent studies have shown that many patients will benefit from a multimodal pharmacological approach following transient cerebral ischaemia, and the potential for combination therapy is highlighted.
