Summary:
The ACCP Stroke Risk Calculator is used to help decide whether or not to use anticoagulant. An approach to the decision of warfarin for oral anticoagulation for atrial fibrillation is suggested in [link url="http://www.aafp.org/afp/2005/0615/afp20050615p2348-f1.pdf" memo="(link)"] Am Fam Physician. 2005 Jun 15;71(12):2348-2350.
1) Use the [link url="../../cardiovascular/chads2/" memo="(link)"] CHADS2 rule as well as the [link url="../../cardiovascular/accp-stroke-risk-calculator/" memo="(link)"] ACCP rule to determine the risk of stroke.
2) If both these measures predict moderate risk of stroke, proceed to calculate the [link url="../../cardiovascular/outpatient-bleeding-risk-index-obri/" memo="(link)"] Outpatient Bleeding Risk Index and weigh the risks versus the benefits.
