Brief Summary
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.

Outcome Measures
Primary Outcomes (1)
predictors of the hemorrhagic infarction type 1
The investigators employed univariate and multivariate Logistic regression analysis to assess the ability of patients' characteristics and risk factors to predict hemorrhagic infarction type 1 after 24-36 hours of receiving alteplase after acute ischemic stroke.
48 hours
Secondary Outcomes (3)
predictors of the hemorrhagic infarction type 2
48 hours
predictors of the parenchymal hematoma type 1

predictors of the parenchymal hematoma type 2
48 hours
Study Arms (2)
Hemorragic transformation group
ACTIVE COMPARATOROne hundred fifty-two acute ischemic stroke (AIS) patients who had hemorrhagic transformation of brain infarction after 24-36 hours of receiving alteplase.
non-hemorragic transformation group
ACTIVE COMPARATORFour hundred sixty-four acute ischemic stroke (AIS) patients did not have a hemorrhagic transformation of brain infarction after 24-36 hours of receiving alteplase.
Interventions
Following the guidelines set by the American Heart Association/American Stroke Association (AHA/ASA), inclusion and exclusion criteria for alteplase were established; 0.9 mg/kg of alteplase up to a maximum dose of 90 mg was administered intravenously to eligible individuals within 4.5 hours of the beginning of their clinical manifestations (10% bolus, 90% infusion in 1 hour). After receiving IV-alteplase, all patients continued their management and rehabilitation in the stroke unit.
Eligibility Criteria
You may qualify if:
- The investigators enrolled individuals of both genders, aged between 18 and 75, who presented with acute first-ever ischemic stroke and were eligible for thrombolysis.
You may not qualify if:
- The investigators excluded patients who had not been followed up on for 90 days after enrollment,
- Those with alteplase contraindications or did not receive the total dose of alteplase due to any reason were excluded
- The investigators excluded patients with a known history of persistent or recurrent CNS pathology (e.g., epilepsy, meningioma, multiple sclerosis, history of head trauma with a residual neurological deficit).
- The investigators excluded patients who had recurrent ischemic stroke diagnosed by appropriate clinical history and/or MRI brain findings.
- The investigators excluded patients with symptoms of major organ failure, active malignancies, or an acute myocardial infarction within the previous six weeks.
- The investigators also excluded pregnant and lactating patients with stroke due to venous thrombosis and stroke following cardiac arrest
