Left ventricle mitochondrial function.

<p>Respiration rates corrected for wet mass (A) and citrate synthase activity (B); oxidative phosphorylation coupling efficiency (OCE) as a marker of mitochondrial coupling (C); and ratio between octanoyl carnitine- and pyruvate-supported respiration (FAO) as a marker of preference for fatty acid oxidation (D) after normoxia (N, white), short-term hypoxia (H2, light blue) or sustained hypoxia (H14, dark blue). * <i>p</i> ≤ 0.05, ** <i>p</i> ≤ 0.01 vs. normoxia; † <i>p</i> ≤ 0.05 vs. short-term hypoxia. Data represent mean ± SEM.
