STROKE-ANTICOAGULANT THERAPY

From NeuroRehab.wiki

SUMMARY

1. Immediate anticoagulant therapy in patients with acute ischemic stroke is not associated with any significant net short- or long-term benefit.

2. Best reason to anticoagulate for cardiac sources of emboli: non-valvular AF & mural thrombus from MI[1].

3. Among patients with non-valvular AF, anticoagulation can reduce stroke by 60%[2].

4. Agents used: Warfarin (inhibits Vit K-dependent coagulation factors, for valvular & non-valvular AF); Dabigatran (direct thrombin inhibitor, for non-valvular AF); Rivaroxaban & Apixaban (factor Xa inhibitors, for non-valvular AF).
