Brief Summary

The benefit of intravenous tenecteplase in very old patients with acute ischemic stroke (AIS) remain uncertain. This real-world study aims to evaluate the effectiveness and safety of intravenous tenecteplase in AIS patients aged 80 years or older within 4.5 hours of symptom onset.

Study Arms (2)

Control group

Standard medical treatment

Other: Standard medical care

Tenecteplase group

Intravenous tenecteplase thrombolysis

Drug: Tenecteplase (TNK) (0.25 mg/kg, to maximum of 25mg)Other: Standard medical care

Interventions

Tenecteplase is administered as a single intravenous bolus at a dose of 0.25 mg/kg, with a maximum of 25 mg.

Tenecteplase group

Standard medical treatment should adhere to clinical guidelines and usual care at site, including antiplatelet therapy, anticoagulant therapy, lipid-lowering therapy, antihypertensive drugs, etc., as determined by the local investigators.

Sampling MethodNon-Probability Sample
Study Population

This study will consecutively screen patients with acute ischemic stroke (AIS) who are over 80 years of age and arrive at the hospital within 4.5 hours of symptom onset.

You may qualify if:

  • Age \> 80 years;
  • Clinically diagnosed with acute ischemic stroke and arrived at the hospital within 4.5 hours of symptom onset;
  • Informed consent signed by the patient or legally authorized representative.

You may not qualify if:

  • Any contraindication to intravenous thrombolysis (excluding age);
  • Previous treatment with other thrombolytic agents such as alteplase, urokinase, plasminogen activator, or reteplase;
  • Current participation in other interventional studies;
  • The investigator deems the patient unsuitable for this study or the study might pose significant risk to the patient (e.g., due to psychiatric disorders, cognitive or emotional impairments that prevent understanding or adherence to study procedures and/or follow-up).
