Stroke; a journal of cerebral circulation
-
Treatments for acute ischemic stroke have evolved as knowledge about the pathophysiology of ischemic brain injury has advanced. Treatment strategies under development are aimed at offering neuroprotection acutely after focal cerebral ischemic injury, but delayed initiation of therapy may reduce efficacy. Pretreatment before ischemia begins could offer distinct advantages in patient groups at high risk for ischemic stroke. ⋯ The possibility of ameliorating the consequences of an acute ischemic stroke by pretreating high-risk patients with appropriate neuroprotective agents needs to be explored. Several types of high-risk population for prophylactic neuroprotection can be envisioned and then studied in clinical trials.
