Task: Answer Verification
Input (English): Question: Is persistent atrial fibrillation associated with thrombomodulin level increase in efficiently anticoagulated patients?
Answer: Plasma sTM concentration was lower in patients with persistent AF and normal left ventricle systolic function than in patients with sinus rhythm, presumably due to chronic oral anticoagulant therapy in the AF group. CV has no impact on sTM plasma level evaluated 24 hours after sinus rhythm restoration.
Output (English): no
