Arvanitis P et al. [31] demonstrated that interleukin-6, high-sensitivity cardiac-troponin-T, NT-proBNP, prothrombin fragment 1 + 2, and fibrinogen decreased significantly after effective ECV, indicating that the increase in all these inflammatory, cardiac, and coagulation biomarkers was a direct consequence of AF [55,56,57,58]. Here, NPPB is linked to atrial fibrillation.
