CHADS Score

CHADS Score

CHADS score or CHADS2 score is a clinical prediction rule for estimating the risk of stroke in patients with nonrheumatic atrial fibrillation (AF), a common and usually benign heart arrythmia. It is used to determine the degree of anticoagulation therapy required,cite journal | title=Selecting patients with atrial fibrillation for anticoagulation: stroke risk stratification in patients taking aspirin | journal=Circulation | year=2004 | volume=110 | issue=16 | pages=2287–92 | author=Gage BF, van Walraven C, Pearce L, "et al." | pmid=15477396 | doi=10.1161/01.CIR.0000145172.55640.93 | url=http://circ.ahajournals.org/cgi/content/full/110/16/2287] since AF can cause stasis of blood in the upper heart chambers, leading to the formation of a mural thrombus that can dislodge into the blood flow, reach the brain and cause a stroke. A high CHADS2 score corresponds to a greater risk of stroke, and vice-versa. The CHADS2 score was validated by a study of nonrheumatic atrial fibrillation patients aged 65 to 95 who were not prescribed the anticoagulant warfarin.cite journal |author=Gage BF, Waterman AD, Shannon W, Boechler M, Rich MW, Radford MJ |title=Validation of clinical classification schemes for predicting stroke: results from the National Registry of Atrial Fibrillation |journal=JAMA |volume=285 |issue=22 |pages=2864–70 |year=2001 |url=http://jama.ama-assn.org/cgi/content/full/285/22/2864 |pmid=11401607 |doi=]
