Figure 3.

Cardiac atrial tissue gene expression of Collagen 1 (A), Collagen 3 (B), BNP (C), GC‐A (D), and NPRC (E) with significant differences observed between AF and Controls in all except BNP and GC‐A.

Higher serum BNP levels were observed in patients with AF compared with Controls (F). Serum BNP data are not normally distributed and are presented as medians (line), interquartile ranges (box) and ranges (whiskers). AF indicates atrial fibrillation; BNP, B‐type natriuretic peptide; GG‐A, Guanyl‐cyclase‐A, also known as natriuretic peptide receptor A; and NPRC, natriuretic peptide receptor C.
