Retinal scans and new therapies offer insights into atrial fibrillation management

New research published in PLOS Digital Health suggests that retinal scans may identify signs of atrial fibrillation up to four years before a clinical diagnosis. By analyzing data from large British cohorts, including the AlzEye database at Moorfields Eye Hospital and the UK Biobank, researchers found that microvascular and neural changes in the retina, detectable via optical coherence tomography (OCT), can serve as early indicators of this common cardiac rhythm disorder.

Separately, medical specialists are reassessing atrial fibrillation management in patients with obstructive hypertrophic cardiomyopathy (oHCM) following the establishment of cardiac myosin inhibitors (CMIs) as a first-line therapy. Clinicians are evaluating the use of antiarrhythmics and the timing of procedural referrals, such as catheter ablation, within this evolving treatment landscape. While CMIs offer new therapeutic flexibility, managing atrial fibrillation remains a priority due to the increased risk of stroke and heart failure associated with the condition.
