Hyperacute therapy of ischemic stroke: intravenous thrombolysis.
Stroke is the third most common cause of death in the United States following heart disease and cancer. Following the success of thrombolysis for myocardial infarction in the early 1990s, major trials for evaluation of this new therapeutic approach for ischemic stroke were initiated. The majority of ischemic strokes are due to occlusion of a cerebral vessel by a blood clot. Occlusion of a cerebral blood vessel leads to a core of infracted tissue surrounded by a relatively hypoperfused but viable brain tissue (the ischemic penumbra), which can be potentially salvaged by rapid recanalization of the target vessel. The underlying rationale for introduction of thrombolytic drugs is the lysis of an obliterating thrombus and reestablishment of blood flow. In this article we review the major intravenous thrombolysis trials leading to approval of intravenous recombinant tissue plasminogen activator, the only FDA approved treatment available today for acute ischemic stroke.
