For Anticoagulation, These Times They are a-Changin’

Get to know the non-Vitamin K oral anticoagulants, as The Curbsiders discuss these novel medications and other changes associated with the updated 2016 CHEST guidelines for anticoagulation.

Take Home Points:

  1. Rivaroxaban, apixaban, edoxaban and dabigatran are the new oral anticoagulants (NOACs). In general they are as safe and effective as warfarin for VTE and afib.
  2. CHEST guidelines were updated Jan 2016. Highlights include:
    1. NOACs as first line for VTE in patients without cancer.
    2. Low risk patients with subsegmental PE do not always require anticoagulation
  3. Fall related bleeding is commonly overestimated. Several warfarin trials showed that fall related bleeds are uncommon and fall related intracranial hemorrhage is a rare complication.

    A few things on this one. Overall great show. I learn something every time. But, please don't record in the bathroom anymore. The acoustics really are lousy. Second, a substantial PE is below the segmental arteries. Main PA>>segmental PA. Just like trachea>>mainstem bronchi>>segmental bronchi.
