State III myocardial respiration on octanoyl-carnitine (a, c) and on the citrate cycle-derived substrates glutamate and succinate (b, d) and mRNA expression of NDUFS1 and CPT1B in myocardial tissue specimens from patients suffering from terminal heart failure and heart transplant recipients. a, b Comparison of maximal myocardial respiration. Student's t-test. c, d Correlation of maximal myocardial respiration and cardiac index measurements. Spearman correlation. e, f Expression of NDUFS1 and CPT1B mRNA. Student's t-test. n = 40 (HF, patients suffering from terminal heart failure; n = 4 in mRNA measurements), n = 29 (HTX, heart transplant recipients; n = 21 in mRNA measurements). AU arbitrary unit. ***p < 0.001, ****p < 0.0001
