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
