NCT06337175

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

    48 hours

  • predictors of the parenchymal hematoma type 2

    48 hours

Study Arms (2)

Hemorragic transformation group

ACTIVE COMPARATOR

One hundred fifty-two acute ischemic stroke (AIS) patients who had hemorrhagic transformation of brain infarction after 24-36 hours of receiving alteplase.

Drug: Alteplase

non-hemorragic transformation group

ACTIVE COMPARATOR

Four hundred sixty-four acute ischemic stroke (AIS) patients did not have a hemorrhagic transformation of brain infarction after 24-36 hours of receiving alteplase.

Drug: 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

Age18 Years - 75 Years
Sexall
Healthy VolunteersNo
Age GroupsAdult (18-64), Older Adult (65+)

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
