A subanalysis of the Find-AFRANDOMISED trial of 398 stroke patients without AF showed that the median BNP level was higher in patients with paroxysmal AF detected by frequent and longer Holter ECG monitoring than in patients without AF (57.8 vs. 28.3 pg/mL, respectively, p = 0.0003) (38). Here, NPPB is linked to atrial fibrillation.
