TNK Up to 24 Hours for Stroke?
Spoon Feed
In patients with large vessel occlusions(LVO) presenting 4.5-24 hours after onset, without access to endovascular thrombectomy (ET), tenecteplase(TNK) administration bested standard medical treatment(SMT) in 90-day disability-free recovery.

Can We Use Lytics for Stroke Patients on a DOAC?
Spoon Feed
For acute ischemic stroke patients with recent DOAC ingestion who (1) had their DOAC level measured, (2) had DOAC reversal with idarucizumab, or (3) inadvertently received thrombolytics with DOAC subsequently discovered, there was not evidence of increased significant intracranial hemorrhage associated with off-label thrombolytic therapy.

The Endovascular Therapy Train Continues Onward
Spoon Feed
This was an exploratory analysis of the recently published SELECT2 trial, which randomized 352 adults with acute ischemic stroke due to carotid or M1 MCA occlusion to endovascular thrombectomy (EVT) or medical management. The current analysis showed that EVT was superior in functional outcomes across a variety of ischemic severities and penumbra profiles on imaging.

Time-Dependent Benefit of IV Thrombolysis Before Thrombectomy
Spoon Feed
In patients with anterior circulation large-vessel occlusion (LVO) stroke presenting to thrombectomy capable stroke centers, the benefit of intravascular thrombolysis in the setting of endovascular thrombectomy appears to be time-dependent.

Spoon Feed
In this retrospective cohort study, there was no increased risk of intracranial hemorrhage, major bleeding, or in-hospital mortality in patients taking non-vitamin K antagonist oral anticoagulants compared to those not taking anticoagulants, but read the fine print.
TENSION RCT – Thrombectomy for Large-Infarct Volume Strokes
Spoon Feed
Endovascular thrombectomy plus medical care is better than medical care for patients with large vessel occlusion (LVO), even with established large infarcts.

What’s the BEST Target SBP Post-Embolectomy for Stroke?
Spoon Feed
More aggressive systolic blood pressure (SBP) goals, beyond keeping it <180 mmHg, probably don’t make much of a difference in outcomes for patients who have undergone endovascular therapy for ischemic stroke.

This ACEP Clinical Policy examined four specific clinical questions related to ED management of acute ischemic stroke, which are summarized below.
Dual Antiplatelets or Lytics for Minor Stroke?
Spoon Feed
In minor acute ischemic stroke (AIS) patients presenting within 4.5 hours of onset, dual antiplatelet therapy (DAPT) is non-inferior to intravenous alteplase for excellent neurologic outcome at 90 days.

TRACE-2 RCT – Tenecteplase vs Alteplase for Stroke
Spoon Feed
Tenecteplase was non-inferior to alteplase in patients with acute ischemic stroke who were eligible for intravenous thrombolytic therapy but ineligible or refused endovascular thrombectomy.
