CoQ10@TNPs reduced cold I/R injury and improved cardiac graft function. A Function of the cardiac graft determined by ultrasound scanning on day 1 post-transplantation. B Beating score of the cardiac graft on day 1 post-transplantation. C Ejection fraction of the cardiac graft on day 1 post-transplantation. D Fractional shortening of the cardiac graft on day 1 post-transplantation. E HE staining of cardiac grafts on day 1 post-transplantation. F–H The serum content of LDH, cTnI, and CK-MB in the recipient. Data are represented as the mean ± SD (n = 5). ns: no significance; *p < 0.01; **p < 0.01; ***p < 0.001
