AF patients taking OACs face frequent extracranial bleeds (26% incidence), according to an analysis of pooled data. @DebSiegal shares that deprescribing concomitant antiplatelet therapy or NSAIDs can help! bit.ly/4bLREHc

🎉 Congratulations to Dr. @sudeeppappur and the entire #EPCATIII team! A true highlight of #ISTH2026 in Paris: a Late-Breaking Abstract with simultaneous publication in @NEJM. Practice-changing results showing that aspirin alone after total hip or knee arthroplasty was noninferior to an initial 5-day course of rivaroxaban followed by aspirin for preventing symptomatic VTE, with no clinically meaningful difference in bleeding. nejm.org/doi/full/10.1056/NE… @ThrombosisCan @canvector @isth

Rivaroxaban Then Aspirin vs. Aspirin Alone after Total Hip or Knee Arthroplasty | NEJM

Aspirin after an initial short course of rivaroxaban has been shown to be safe and effective for the prevention of venous thromboembolism after total hip or total knee arthroplasty, but uncertainty...

Apixaban reduced stroke by 37% in subclinical AF, but increased major bleeding. What did those bleeding events actually look like? In ARTESiA: Mostly GI bleeding, Low intracranial & fatal rates, Majority not clinical emergencies. Dr. Deborah Siegal joins CLOT Conversations to break it down.
