Background High blood pressure is common in acute stroke and is a predictor of poor
outcome; however, large trials of lowering blood pressure have given variable results, and …

Objective To assess the association of baseline imaging markers of cerebral small vessel
disease (SVD) and brain frailty with clinical outcome after acute stroke in the Efficacy of Nitric …

Background and Purpose—Our aim was to identify whether particular subgroups of patients
had an unacceptably high risk of symptomatic intracranial hemorrhage or low chance of …

Background and Purpose—Blend, black hole, island signs, and hypodensities are reported
to predict hematoma expansion in acute intracerebral hemorrhage. We explored the value of …

Background and Purpose—Pilot trials suggest that glyceryl trinitrate (GTN; nitroglycerin) may
improve outcome when administered early after stroke onset. Methods—We undertook a …

Objective: To investigate whether the location and extent of the CT hyperdense artery sign
(HAS) at presentation affects response to IV alteplase in the randomized controlled Third …

Neurological deterioration is common after intracerebral hemorrhage (ICH). We aimed to
identify the predictors and effects of neurological deterioration and whether tranexamic acid …

Background and Purpose—The Efficacy of Nitric Oxide in Stroke (ENOS) trial found that
