Evaluation of the impact of DHT on cardiac morphology in rats with MI-induced heart failure. (A) Representative ECG images confirming the results of myocardial infarction surgery in rats with heart failure. (B) Representative images of cardiac tissue TTC staining showing nonischemic areas (red-colored regions) and infarct portions (pale-colored regions indicated by red arrows) in shortened sections from the cardiac apex. (C) Quantification of the infarct area in the cardiac tissue. (D) Representative images of cardiac chambers for each group. (E) Bar graph illustrating the ratios of HW/BW. (F) Bar graph displaying the left ventricle inner diameter area percentage. ECG, electrocardiogram; TTC, triphenyltetrazoliumchloride; MI, myocardial infarction; DHT, dohongsamul-tang; HW, heart weight; BW, body weight. Data values are presented as means ± SE. ** p < 0.01, *** p < 0.01 vs. Sham; # p < 0.05, ## p < 0.01 vs. MI group.
