NT-proBNP levels were higher in women than in men (239.0 [130.5, 561.5] vs 156.0 [82.6, 359.0] pg/ml; p<0.001), and in patients with hypertension (225.0 [114.0, 530.0] vs 111.5 [62.7, 223.0] pg/ml; p<0.001) and with previous atrial fibrillation (886.0 [316.0, 1860.0] vs 162.0 [85.9, 378.0] pg/ml; p<0.001) as compared with those not suffering these conditions. Here, NPPB is linked to atrial fibrillation.
