NPPB and atrial fibrillation: Screening-detected AF was most common in normotensive participants with increased NT-proBNP (n = 90/1922, 4.7 %), followed by patients with both NT-proBNP > 125 ng/l and SBP ≥ 140 mmHg, (AF = 65/1741, 3.7 %) compared to the low-risk group (AF = 2/1444, 0.1 %), p < 0.001.
