Even episodes of atrial fibrillation tied to ischemic stroke risk
Episodes of atrial fibrillation (AF) lasting at least 5.5 hours are associated with a higher risk of ischemic stroke, particularly in the first few days, a study carried out in patients with cardiac implantable electronic devices (CIEDs) confirms. Further, the risk of stroke was most apparent in the first 1 to 5 days after the AF episode after which it waned away and then dissipated...
Episodes of atrial fibrillation (AF) lasting at least 5.5 hours are associated with a higher risk of ischemic stroke, particularly in the first few days, a study carried out in patients with cardiac implantable electronic devices (CIEDs) confirms. Further, the risk of stroke was most apparent in the first 1 to 5 days after the AF episode after which it waned away and then dissipated quickly.
The study, published in the journal JAMA Cardiology, supports AF being a causal risk factor than the idea of a risk marker and that paroxysmal atrial fibrillation poses a risk of stroke during and for a short time and the risk decreases rapidly.
