Impact of Undertreated Antithrombotic Therapy on Adverse Patient Outcomes

A Scientific Statement From the American Heart Association.

The American Heart Association highlights the substantial clinical and public health burden of antithrombotic undertreatment in patients with atrial fibrillation, venous thromboembolism, or…

COAST-AF

ablating low-voltage areas on top of pulmonary vein isolation does not significantly reduce recurrence of persistent atrial fibrillation overall, but does in the half of patients who have such areas

Presented in LBS.04 at AHA 2026 (Sunday 8 November) and published simultaneously in JAMA. COAST-AF (Characterization of Arrhythmia Substrate to Ablate Persistent Atrial Fibrillation) is a…

Anticoagulation in Atrial Fibrillation With Previous Intracranial Bleeding

Competing Adverse Events in a Nationwide Cohort.

In a nationwide Finnish cohort of 1,502 patients with atrial fibrillation and prior intracranial bleeding, the 1-year risk of ischemic stroke fell from 4.1% with no anticoagulation to 0.7% with DOACs…

Catheter ablation for symptomatic atrial fibrillation (PVI-SHAM-AF)

a randomised, double-blind, sham-controlled, multicentre trial.

In the double-blind, sham-controlled PVI-SHAM-AF trial, 262 patients with symptomatic paroxysmal or persistent atrial fibrillation were randomised to catheter ablation or a sham procedure. At six…

Device-detected atrial fibrillation after ARTESiA and NOAH-AFNET 6

from episode burden to net clinical benefit.

This narrative review synthesizes evidence from the ARTESiA and NOAH-AFNET 6 trials regarding anticoagulation for device-detected atrial high-rate episodes and subclinical atrial fibrillation. While…

Walking a tightrope

the safety and efficacy of oral anticoagulants in atrial fibrillation patients with prior intracranial haemorrhage: a systematic review and meta-analysis.

A systematic review and meta-analysis evaluated direct oral anticoagulants (DOACs) versus vitamin K antagonists (VKAs) in patients with atrial fibrillation and a history of intracranial haemorrhage…

LIBREXIA ACS

milvexian prevents no events after an acute coronary syndrome and does not bleed less, a blow to the factor XI hypothesis in ACS

The full results of the trial stopped for futility in November 2025: 14,194 patients within 7 days of an ACS with at least two risk factors, milvexian 25 mg twice daily or placebo on top of…

EPIDAURUS

prasugrel or ticagrelor with a DOAC after infarction in atrial fibrillation triples major bleeding, the trial was stopped early

Randomised trial stopped early for safety after 602 of 1,474 planned patients with AF and myocardial infarction: DOAC plus one month of prasugrel or ticagrelor versus DOAC plus clopidogrel (with…

SINGLE-AF

a DOAC protects patients with atrial fibrillation and a single stroke risk factor, without excess major bleeding

The first randomised trial in the guideline grey zone: 1,803 Korean patients with AF and a CHA2DS2-VASc score of 1 (men) or 2 (women) were randomised to apixaban or rivaroxaban versus no…

Factor XI inhibition

the hypothesis, the promise and the LIBREXIA ACS lesson

Factor XI inhibition promises antithrombotic effect without the bleeding cost, but the field keeps hitting reality: after asundexian, the 14,000-patient LIBREXIA ACS trial of milvexian was halted for…
