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.
