Analysis of autopsy heart samples of non-COVID-19 and COVID-19 patients

(A) H&E staining of autopsy heart samples of non-COVID-19 and COVID-19 patients (n = 2 non-COVID-19 subjects, n = 4 COVID-19 patients). Scale bar, 50 μm.

(B and C) Heatmap of ROS-associated genes (B) and CM function-associated genes (C) in autopsy heart samples of non-COVID-19 and COVID-19 patients (n = 3 non-COVID-19 subjects, n = 3 COVID-19 patients). Data are presented as the Z score.

(D and E) Immunofluorescence staining (D) and the relative mean intensity of CASP3 (E) in cTNT⁺ cells in autopsy heart samples of non-COVID-19 and COVID-19 patients (n = 2 non-COVID-19 subjects, n = 4 COVID-19 patients). Scale bar, 50 μm.

Data are presented as mean ± SD. p values were calculated by unpaired two-tailed Student's t test. ^∗∗∗p < 0.001.
