Adequate secondary prevention in survivors of intracerebral hemorrhage (ICH) who also have atrial fibrillation (AF) is a long-standing clinical dilemma because these patients are at increased risk of recurrent ICH as well as of ischemic stroke. The efficacy and safety of oral anticoagulation, the standard preventive medication for ischemic stroke patients with AF, in ICH patients with AF are uncertain. PRESTIGE-AF is an international, phase 3b, multi-center, randomized, open, blinded end-point assessment (PROBE) clinical trial that compared the efficacy and safety of direct oral anticoagulants (DOACs) with no DOAC (either no antithrombotic treatment or any antiplatelet drug).

Article Synopsis
  • Many patients with atrial fibrillation (AF) are not receiving or are stopping oral anticoagulation therapy, despite its importance for stroke prevention.
  • While direct oral anticoagulants (DOACs) are available, issues like bleeding risks, poor compliance, and aversion to treatment contribute to this problem.
  • A recent expert consensus guide highlights left atrial appendage closure (LAAC) as a safe alternative for stroke prevention in patients who cannot use long-term anticoagulation, detailing the devices, implantation technique, and follow-up requirements for non-implanting physicians.

Article Synopsis
  • Atrial fibrillation (AF) patients in the ICU experience significant mortality risks, heavily influenced by glycaemic variability (GV), which relates to poor sugar control and can worsen their prognosis.
  • Higher GV levels correlate with increased all-cause mortality at 30, 90, and 360 days after ICU admission, indicating a need for better glycaemic management.
  • Machine learning models, particularly using light gradient boosting, show promise in predicting 30-day mortality among AF patients based on GV and other clinical features.

Aims: The CHA2DS2VASc score is recommended for stroke risk stratification in patients with atrial fibrillation (AF). This score assigns one extra point to female sex based on evidence from the early 2000s, suggesting higher thromboembolic risk in women. This incremental risk of thromboembolism in women has decreased over time between 2007 and 2018, becoming non-significant in recent years.

Atrial fibrillation (AF) is common and warrants consideration of oral anticoagulant (OAC) medication. Usually, the decision is straightforward, following the pathway outlined in the European Society of Cardiology's guideline; however, certain situations fall outside of this evidence base - such as a diagnosis of subclinical AF made via implanted devices or wearable electrocardiogram monitors, or alternatively diagnosis of 'secondary AF' following a major stressor. Subclinical AF is associated with stroke, though not to the extent of clinical AF, and the benefits of anticoagulation appear to be lower.
