Myocardial concentrations of coenzyme Q10 and citrate synthase (CS) activity in control dogs with no evidence of heart disease (CON, n = 10), and in CKCS with MMVD in stage B1 (n = 11), stage B2 (n = 5) and stage C with CHF (n = 14). Horizontal lines indicate median values. (A) Total myocardial Q10, (B) Ubiquinol, the reduced form of Q10, (C) Ubquinone, the oxidized form of Q10. (D) Oxidation ratio (% of total Q10 that is oxidized). (E) Citrate Synthase activity, (F) Ratio between Q10 and citrate synthase activity in the disease groups.
