Brief summary
Previous study showed that the proportions of hemorrhagic Infarction after intravenous thrombolysis were 24.2% and 32.5% in the control group and the alteplase group, and most of them were asymptomatic. Hemorrhagic Infarction was a part of the natural progression after acute ischemic stroke. Previous study have shown no significant relationship between hemorrhagic Infarction and poor outcome in acute ischemic stroke (AIS) patients. In this study, a randomized controlled trial will be conducted to explore the efficacy and safety of early antiplatelet therapy after hemorrhagic infarction in acute ischemic stroke treated with intravenous thrombolysis.
Interventions
Early Antiplatelet Therapy is administered within 24 to 48 hours after stroke onset and the dose is determined by the clinician. Aspirin was chosen for antiplatelet therapy.
Antiplatelet therapy will be delayed to beyond 48 hours after stroke onset and may not be initiated until hemorrhagic Infarction has been confirmed absorbed.
