Atrial fibrillation
⎯ Most common heart arrhythmia
⎯ Affects ~ 7 million US, especially the elderly
⎯ Increase stroke risk by 4-5 X and mortality 2 X

CHEST 2018 Guidelines
• Atrial fibrillation (Strong recommendations)
⎯ Oral anticoagulation• CHA2DS2VASc score > 1 male or > 2 female
⎯ HAS-BLED score
⎯ DOACs over vitamin K antagonist (VKA)
⎯ If VKA with time in therapeutic range (TTR) < 65%, switch to DOAC

1. Triple therapy with aspirin 81mg daily is used until hospital discharge. 2. For bleeding risk use HAS-BLED score: Low risk = 0-2, high risk = 3-4, very high risk >4.3. High atherothrombotic risk: For elective PCI use SYNTAX score; for ACS, GRACE score >140; stenting of the left
main, proximal LAD, proximal bifurcation; recurrent MIs; stent thrombosis etc. 4. DOAC is preferred over warfarin unless CI. Clopidogrel is preferred P2Y12 inhibitor; ticagrelor may be considered
