Similarly, during ILR monitoring with a median duration of 3.27 years (interquartile range, 3.06–3.45 years), participants with NT-proBNP >15 pmol/L were also more likely to experience ILR-detected AF episodes lasting ≥24 hours compared with those having lower levels (HR 2.45 [95% CI, 1.46–4.10]; Figure S4). This evidence concerns the gene NPPB and atrial fibrillation.
