@misshyd - bensha - ArchivalUser - 08-05-2011 Can you explain stroke management including the primary/sec prvention CHADS2 score use in patients with lone afib and patients without afib. I listened to archers and followed Dr.Red's notes, which is real good. But I am not clear on this subject. Also TIA alone. It would be a great help. Thanks. 0 - ArchivalUser - 08-05-2011 bensha, sure let us discuss afib: 1. Primary prevention of stroke means we want to prevent first episode of stroke in an at-risk patient who NEVER HAD A STROKE. Secondary prevention means we want to prevent further or recurrent strokes in a patient with a history of CVA already. 2. One of the primary prevention strategies is using aspirin or warfarin in a patient who has risk factors for stroke. Other primary prevention strategies are lifestyle modifications, smoking cessation, hypertension control etc Primary prevention of stroke in atrial fibrillation: the primary prevention strategy here depends on what is the risk of having a stroke in a patient with Afib. If Afib is the only risk factor and no other risk factors for stroke (chads2) then such afib is called "LONE AFIB" for prevention purposes. In lone afib, aspirin is enough for stroke prevention CHADS2 criteria: Congestive heart failure (any history) 1 point Hypertension (prior history) 1 point Age ≥75 years 1 point Diabetes mellitus 1 point Previous TIA or CVA - 1 point So now decision making and options: Afib + CHADS2 score zero = Aspirin alone or no anti-thrombotic therapy Afib + CHADS2 score one = Aspirin alone or coumadin Afib + CHADS2 score two or more = Coumadin preferred if patient has any of CHADS2 score 0 - ArchivalUser - 08-05-2011 small correcton....2 points for TIA OR CVA 0 - ArchivalUser - 08-06-2011 sorry rocky28 , yes it is 2 points for cva or tia. thx |
