Evaluating factors predicting brain hemorrhage after stroke treatment with alteplase

Predictors of Post-alteplase Different Subtypes of Hemorrhagic Transformation of Brain Infarction in the Middle East

Phase 4 Interventional Kafrelsheikh University · NCT06337175

What this trial studies

This study investigates the predictors of post-alteplase hemorrhagic transformation in patients who have experienced an acute ischemic stroke. Conducted as a prospective cohort study, it screened 1450 patients and included 616 who met the criteria for thrombolysis with alteplase. The researchers assessed various characteristics, including door-to-needle time and stroke risk factors, to determine their relationship with different subtypes of hemorrhagic transformation. Follow-up brain imaging was performed to identify these subtypes in patients treated within four and a half hours of stroke onset.

Who should consider this trial

Good fit: Ideal candidates for this study are individuals aged 18 to 75 who present with their first-ever acute ischemic stroke and are eligible for thrombolysis.

Not a fit: Patients with contraindications to alteplase, recurrent ischemic strokes, or significant comorbidities such as major organ failure or active malignancies may not benefit from this study.

Why it matters

Potential benefit: If successful, this study could help identify patients at higher risk for hemorrhagic complications after alteplase treatment, leading to improved patient management and outcomes.

How similar studies have performed: Similar studies have explored predictors of hemorrhagic transformation, but this specific approach focusing on post-alteplase outcomes is relatively novel.

Inclusion Criteria:

* 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.

Exclusion Criteria:

* 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.
