Ischemic Stroke Clinical Trial
Official title:
Predictors of Post-alteplase Different Subtypes of Hemorrhagic Transformation of Brain Infarction in the Middle East
The investigators evaluated whether the characteristics of ischemic stroke patients, door-to-needle time, and stroke risk factors were predictive variables for different subtypes of post-alteplase hemorrhagic transformation of brain infarction.
Investigators conducted a prospective cohort study between June 2021 and October 2023. They screened 1450 patients who presented with AIS and received alteplase and included 616 AIS patients who met the inclusion criteria and were diagnosed based on a thorough clinical assessment, including a detailed medical history, physical examination, and specific brain imaging results and treated with alteplase within four and half hours of stroke onset. The investigators assessed the patients' follow-up brain imaging to detect the subtypes of hemorrhagic transformation after receiving alteplase. The study consisted of two distinct groups. The first group consisted of 464 patients who did not experience hemorrhagic infarction, while the second group comprised 152 patients who experienced hemorrhagic infarction. The investigators evaluated whether the characteristics of ischemic stroke patients, door-to-needle time, and stroke risk factors were predictive variables for different subtypes of post-alteplase hemorrhagic transformation of brain infarction. ;
