Atrial fibrillation density, reflecting temporal episode clustering, independently predicts ischaemic stroke risk and improves risk stratification beyond traditional AF burden metrics, enabling more precise stroke prevention strategies.
This Finnish nationwide study demonstrates that patients with atrial flutter have a substantially lower risk of ischaemic stroke compared to those with atrial fibrillation, highlighting important differences in thromboembolic risk profiles
New research published in the European Heart Journal identifies Dickkopf-related protein 2 (DKK2) as a primary driver of neurovascular injury post-stroke. By suppressing Wnt signalling, DKK2 exacerbates neuronal death and blood-brain barrie
