Thrombolytic drugs for acute ischemic stroke may reduce death or deterioration, especially when computed tomographic scans guide treatment. Further large-scale trials are warranted to confirm these findings and influence clinical practice.

Area of Science:

  • Neurology
  • Cardiovascular Medicine
  • Pharmacology

Background:

  • Acute ischemic stroke presents a significant clinical challenge.
  • Thrombolytic therapy is a potential treatment option for acute ischemic stroke.
  • Evidence regarding the efficacy and safety of thrombolysis requires further investigation.

Purpose of the Study:

  • To analyze existing randomized trials on thrombolysis for acute ischemic stroke.
  • To assess the impact of thrombolytic treatment on mortality and clinical outcomes.
  • To evaluate the risk of hemorrhagic transformation and edema with thrombolysis.

Main Methods:

  • Systematic review and analysis of six randomized trials of thrombolysis in acute ischemic stroke.
  • Comparative analysis of trials with and without computed tomographic (CT) scanning.

  • Inclusion of both randomized and nonrandomized studies for safety assessment.

    • Main Results:

    • Thrombolytic treatment showed a non-significant 20% increase in death odds and a 30% reduction in death or deterioration odds.
    • Excluding trials without CT scanning revealed a 37% reduction in death odds and a significant 56% reduction in death or deterioration odds.
    • Analysis of all studies indicated no excess risk of hemorrhagic transformation or severe edema.

    Conclusions:

    • Current evidence suggests thrombolysis is a promising treatment for acute ischemic stroke.
    • Computed tomographic scanning may improve outcomes in thrombolysis.
    • Large, well-designed randomized clinical trials are needed to confirm efficacy and guide clinical practice.
