  Figure 1. Pearson’s correlation analysis of Nt-proBNP with GRPS, GCPS, and GLPS in the non-IIM group (a–c) and IIM group (d–f). Notes: *P < 0.05. Actual p value and 95% CI are provided from a–f as follows: a (95% CI: −0.677, −0.151, p = 0.005), b (95% CI: 0.292, 0.750, p < 0.001), c (95% CI: 0.310, 0.758, p < 0.001), (d) (95% CI: −0.548, −0.060, p = 0.017), (e) (95% CI: 0.090, 0.568, p = 0.01), and (f) (95% CI: −0.033, 0.479, p = 0.084). CI: confidence interval; NT-proBNP, N-terminal pro-brain natriuretic peptide; GRPS, global radial peak strain; GCPS, global circumferential peak strain; GLPS, global longitudinal peak strain; IIM, idiopathic inflammatory myopathy.

  Figure 2. Pearson’s correlation analysis of LVEF with GRPS, GCPS, and GLPS in the non-IIM group (a–c) and IIM group (d–f). Notes: *P < 0.05. Actual p value and 95% CI are provided from (a–f) as follows: a (95% CI: 0.717, 0.910, p < 0.001), b (95% CI: −0.949, −0.831, p < 0.001), c (95% CI: −0.808, −0.457, p < 0.001), (d) (95% CI: 0.284, 0.686, p < 0.001), (e) (95% CI: −0.734, −0.370, p < 0.001), and (f) (95% CI: −0.681, −0.274, p < 0.001). Abbreviations as in Table 1 and Fig. 1.

  Figure 3. Cardiac MRI tissue tracking in the four-chamber long-axis, two-chamber long-axis and short-axis cine images at the end-diastole (a–c) and end-systole (d–f). The red and green curves show the endocardial and epicardial borders, respectively; the yellow dots represent the myocardial voxel points. Abbreviations: MRI, magnetic resonance imaging.
