Timing of stroke risk reassessment in atrial fibrillation patients with a CHA2DS2-VA score of 0 or 1: the Norwegian AFNOR study.

ABSTRACT:

Aims

Stroke risk in atrial fibrillation (AF) patients increases over time, but the optimal reassessment interval remains unclear. This study evaluated changes in the CHA2DS2-VA score in AF patients with low (score 0) or intermediate (score 1) stroke risk and explored appropriate reassessment intervals.

Methods and results

Using Norwegian national registries (2011-18), 40 782 individuals with incident AF aged ≥18 years and a low or intermediate CHA2DS2-VA score were identified. Patients were followed from first AF diagnosis until an increase in the CHA2DS2-VA score, and the proportion with increased score was assessed across age groups. The number needed to reassess to detect one new CHA2DS2-VA risk factor was calculated at different time intervals after AF diagnosis. The CHA
