Noninvasive evaluation of skeletal muscle oxidative metabolism after heart transplant

Article Abstract:

Noninvasive tools are used to provide evidence of a significant functional impairment of skeletal muscle oxidative metabolism in Heart Transplant Recipient (HTR), associated with an impaired capacity of O2 delivery to skeletal muscles. The findings confirm the presence of both 'central' (cardiovascular) and 'peripheral' (at the skeletal muscle level) impairments to oxidative metabolism in HTR.

Skeletal muscle VO(sub)2 on-kinetics: set by O(sub)2 delivery or by O(sub)2 utilization? new insights into an old issue

Article Abstract:

Results demonstrate that during muscle transition from resting to contraction, the skeletal muscle VO(sub)2 on-kinetics are not limited by convective oxygen delivery to muscle and peripheral oxygen diffusion. Instead, the intrinsic skeletal muscle oxidative metabolism inertia probably regulates the intracellular respiration in muscle tissues.

Serial assessment of Peak VO2 and VO2 kinetics early after heart transplantation

Article Abstract:

A study was done at serial assessment of both peak VO2 and VO2 kinetics early after heart transplantation. The result suggested that in the absence of structured rehabilitation programs, the patients showed an increase in peak VO2 and improvement of the VO2 kinetic.
