Maximum rate of oxygen consumption related to succinate dehydrogenase activity in skeletal muscle fibres of chronic heart failure patients and controls

Abstract: Previous studies indicate that the low maximum rate of oxygen consumption (VO2max) of chronic heart failure (CHF) patients is not because of impaired pump function of the heart. We hypothesize that VO2 during maximum exercise is determined by the total oxidative capacity of skeletal muscle. VO2max of six controls and 14 CHF patients, New York Heart Association class I-III, was determined using an incremental bicycle ergometer test. Cryostat sections of a biopsy from the quadriceps femoris muscle were incubated… Show more

“…These results fit well to the extrapolated relationship determined previously using different types of single skeletal muscle fibers (van der Laarse et al, 1989). Figure 2 also contains measurements of VO 2,max during a bicycle exercise test and SDH activity measured in biopsies of the vastus lateralis muscle (Bekedam et al, 2002). We conclude on the basis of the results on rat trabeculae and human biopsies that SDH activity determined histochemically allows an estimate of the oxidative capacity of mammalian striated muscle cells.…”

“…The cross-sectional area of these preparations was smaller than 0.035 mm 2 , which is a requirement to prevent hypoxia during these measurements. Open circle: VO 2max of six human subjects, measured using an incremental bicycle exercise test, and mean SDH activity measured in biopsies of the vastus lateralis muscle (data from Bekedam et al, 2002). The s.d.…”

“…To our knowledge, it has never been tested whether, and to what extent, trained humans are able to increase iSDH activity values. This study shows that athletes succeeded in obtaining much greater iSDH activity values (0.147 6 0.034 in DA 660 mm/s) than untrained humans do [0.087 6 0.004 (50)] or than patients with heart failure do [0.048 6 0.004 (50)]. So, even though muscle fiber size and oxidative capacity were inversely related, athletes were able to obtain high iSDH activity values.…”

“…This correlation between anatomical capillary supply and tissue oxidative capacity also seems to apply at a smaller scale of biological control, where the local capillary supply to an individual fibre appears to be positively related to its oxidative capacity (Bekedam et al, 2003). Importantly, in such studies, fibre size was not considered and hence the influence of local diffusion distances on cellular oxygenation cannot be assessed.…”
