Thrombolysis Beneficial for Acute Ischaemic Stroke Regardless of Age and Severity无论年龄大小和严重程度, 溶栓治疗急性脑梗塞有效

A meta-analysis of 6756 patients in nine randomised trials suggested that irrespective of age or stroke severity, and despite an increased risk of fatal intracranial haemorrhage during the first few days after treatment, intravenous alteplase significantly improves the overall odds of a good stroke outcome when delivered within 4•5 h of stroke onset, with earlier treatment associated with bigger proportional benefits. Despite an average absolute increased risk of early death from intracranial haemorrhage of about 2%, by 3—6 months this risk was offset by an average absolute increase in disability-free survival of about 10% for patients treated within 3•0 h and about 5% for patients treated after 3•0 h, up to 4•5 h. Proportional treatment benefits and the relative increase in fatal intracranial haemorrhage from alteplase was similar irrespective of age or stroke severity, but the absolute excess risk attributable to alteplase was bigger among patients who had more severe strokes.
