Why are Antiplatelets used after stroke?
Aggressive medical management including aspirin and clopidogrel for 90 days after stroke from intracranial atherosclerosis reduces stroke recurrence compared to historical controls. Aspirin plus clopidogrel for 21 to 30 days after TIA or minor stroke reduces recurrent stroke.
When do you start anticoagulation after thrombectomy?
At our center, when indicated, we typically initiate anticoagulation if there is small stroke burden (<30 cc) on the postprocedural scan.
What is the initial drug of choice for a patient with ischemic stroke?
An IV injection of recombinant tissue plasminogen activator (tPA) — also called alteplase (Activase) — is the gold standard treatment for ischemic stroke. An injection of tPA is usually given through a vein in the arm with the first three hours. Sometimes, tPA can be given up to 4.5 hours after stroke symptoms started.
When do you start OAC after a stroke?
The American Heart Association and the American Stroke Association recommend that oral anticoagulant (OAC) therapy needs to be started within 14 days after ischemic stroke in patients with NVAF. Similarly, the European Heart Rhythm Association (EHRA) has proposed the “1–3–6–12 day rule”.
What is the chance of having a second stroke?
Even after surviving a stroke, you’re not out of the woods, since having one makes it a lot more likely that you’ll have another. In fact, of the 795,000 Americans who will have a first stroke this year, 23 percent will suffer a second stroke.

How is antiplatelet therapy used to treat stroke?
Anticoagulants at doses to prevent venous thromboembolism are insufficient antithrombotic therapy to prevent recurrent ischemic stroke or TIA. Antithrombotic Trialists, Collaboration. “Collaborative Meta-Analysis of Randomised Trials of Antiplatelet Therapy for Prevention of Death, Myocardial Infarction, and Stroke in High Risk Patients.”
When can a stroke patient begin rehabilitative therapy?
When can a stroke patient begin rehabilitation? Rehabilitative therapy typically begins in the acute-care hospital once the condition has stabilized, often within 48 hours after the stroke. The first steps often involve promoting independent movement to overcome any paralysis or weakness.
Are there any new drugs for acute ischemic stroke?
While the use of these agents for patients with acute ischemic stroke and transient ischemic attacks continues to be the subject of study, substantial evidence is available from completed studies.
