For atrial fibrillation, obese patients again exhibited significantly higher NT-proBNP (7400 ± 2600 pg/mL vs. 4500 ± 2100 pg/mL, p < 0.001), Troponin I (125 ± 330 ng/mL vs. 95 ± 300 ng/mL, p = 0.01), and inflammatory markers like CRP, CK-MB, and D-dimer. Here, NPPB is linked to atrial fibrillation.
