Short-term use (<90 days) of acetylsalicylic acid in combination with clopidogrel? |
Not been shown to increase the risk of bleeding; however, long-term use is not generally recommended for secondary stroke prevention unless there is another indication, such as a drug-eluting carotid artery stent |
|
Common reasons for failure of antiplatelet therapy? (4) |
1. Non-adherence 2. Concomitant use of NSAIDs or COX-2 inhibitors with acetylsalicylic acid 3. Impaired metabolism of clopidogrel (concomitant use with PPIs or other medications; patient may be a genetically poor metabolizer) 4. Poor response (resistance) |
|
Treatment for atrial fibrillation? |
If no contraindications exist, patients with both TIA and AF should begin oral anticoagulation after CT or MRI of the brain has excluded intracranial hemorrhage or large infarct |
|
Choices of anticoagulation for AF and stroke/TIA? (4) |
