Scatter plots of the correlations of the five CMR-measured parameters with the four tested circulating biomarkers in the AF patients. The Y axis of the five plots in the top row is log (hs-CRP), the second row is log (sST2), the third row log (TGF-β1), and the bottom row log (PIIINP), respectively. The X axis of the four plots in the left column is LAV, the second column is LV peak SCS, the third column plots LV peak SCS rate, the fourth column LV early DCS rate, and the right column LV native T1 time, respectively. LAV left atrium volume, LV left ventricle, SCS systolic circumferential strain, DCS diastolic circumferential strain, hs-CRP high-sensitivity C-reactive protein, sST2 soluble suppression of tumorigenicity 2, TGF-β1 transforming growth factor beta-1, PIIINP collagen III N-terminal propeptide
