In Nie et al, the TEM image of the MI +MCC950 + H2 group in Figure 2H and the Masson local image for the MI +MCC950 + H2 group in Figure 3A cannot be used as representative images. The correct figure is shown below. The authors confirm all results and conclusions of this article remain unchanged.

Effects of H2 inhalation on cardiac function and myocardial structure changes in rats. (A) Survival curve of rats of each experimental group; (B) the plasma BNP concentration of each group, n = 5 per group; (C) images illustrating echocardiography of rat's heart; (D–G) EF (%); FS (%); LVIDd and LVIDs (n = 5 per group); (H) TEM images illustrating the cardiomyocytes (×30k magnification, scale bar 100 nm), the arrow indicates the mitochondria of cardiomyocytes; (I) the heart MDA concentration of each group, n = 5 per group; (J) the heart relative ·OH concentration of each group, n = 5 per group. Data are shown by mean ± SEM, ***p < 0.001 vs Sham group. #p < 0.05 ##p < 0.01 ###p < 0.001 vs MI group. &p < 0.05 vs MI + MCC950 group. $$$p < 0.001 vs MI + MCC950 group

Effects of inhalation of H2 on myocardial fibrosis and fibrosis‐related proteins in MI rats. (A) The representative Masson images of rat whole heart and left ventricle; (B) fibrosis area of whole heart sections. n = 5 per group; (C) collagen volume fraction of left ventricle. n = 5 per group; (D) the representative immunohistochemical staining images of α‐SMA and fibronectin expression in each group (×20 magnification, scale bar 50 μm); (E–F) quantification of α‐SMA and fibronectin‐positive cells statistical chart, n = 5 per group; (G) the representative Western blot bands of TGF‐β, α‐SMA, Col I and Col III; (H–K) relative TGF‐β, α‐SMA, Col I and Col III protein level, n = 5. Data are shown by mean ± SEM, ***p < 0.001 vs Sham group. #p < 0.05 ##p < 0.01 ###p < 0.001 vs MI group. &p < 0.05 vs MI +MCC950 group
