CHADS2 score and stroke risk

In case your doctor starts throwing this term at you.
Criteria (mnemonic: CHADS)

1. Congestive Heart Failure (1 point)
   1. Relative risk of Stroke or TIA: 1.4
2. Hypertension (1 point)
   1. Relative risk of Stroke or TIA: 1.6
3. Age over 75 years (1 point)
   1. Relative risk of Stroke or TIA: 1.4
4. Diabetes Mellitus (1 point)
   1. Relative risk of Stroke or TIA: 1.7
5. Stroke or TIA history (2 points)
   1. Mitral Stenosis or prosthetic Heart Valve carry similar risk and also indicate Warfarin
   2. Relative risk of Stroke or TIA: 2.5
   A calculator here: I have a 4% risk without warfarin treatment. I'll have to accept that since I won't go on warfarin again unless absolutely necessary.
