- Description
- Around 15 years have now elapsed since thrombolysis was first shown to be effective for treating acute ischemic stroke, but therapeutic uptake has been modest. As outlined in this Review, research efforts are being directed towards rectifying this situation in a number of ways. First, strategies to enhance thrombolytic efficacy are being tested; these include intravenous and intra-arterial bridging protocols, sonothrombolysis, and the use of alternative thrombolytic agents. Second, means of extending the 4.5-h therapeutic time window up to 6 h, or even up to 9 h in patients selected on the basis of imaging, are being investigated in clinical trials. Prolongation of the time window using neuroprotection to 'freeze' penumbral tissue is also being attempted. Third, attempts are underway to reduce the risk of symptomatic intracerebral hemorrhage (currently affecting about 7% of cases) by refining imaging selection criteria, and through the use of alternative thrombolytic agents, lower doses of tissue plasminogen activator, blood-based biomarkers, and neuroprotectants. Last, in an effort to include more people within the currently accepted therapeutic time window, improvements in prehospital management strategies are being introduced. Elimination of prehospital and in-hospital delays is an urgent priority.
