Tips: RxTx/CTC 2019. Prevention of Ischemic Stroke. Combination therapy (oral anticoagulant plus low-dose ASA) is superior to anticoagulant alone in patients with prosthetic heart valves but carries an increased risk of bleeding episodes. For patients intolerant of ASA, dipyridamole (400 mg/day) plus an oral anticoagulant may be used. This approach has not been validated in clinical trials.
