Comparison of serum cardiac troponin T levels in HI and HI-H2 groups before, at 3, 6 h after insultSerum cardiac troponin T concentrations were measured to assess myocardial injury. Due to sample availability, troponin T could be measured in 9 of 10 piglets in the HI group and 4 of 7 piglets in the HI–H₂ group.Troponin T levels at 6 h were significantly lower in the HI–H₂ group than in the HI group (HI: 0.16 ± 0.04 ng/mL; HI–H₂: 0.10 ± 0.02 ng/mL, p = 0.048). Closed circle (●), HI group (n = 9); open circle (〇), HI-H2 group (n = 4). Data are presented as mean ± SD. p < 0.05 vs. HI group.
