Discussion

Member takes

Implication

Indicates similar oxygen supply-demand balance in skeletal muscle and LV; hypothesis-generating for regional cardiac differences, requires prospective validation.

Structured PICO

Population

Untrained and trained men (leg muscle) and patients subjected to open heart surgery (myocardium from apex of left ventricle and papillary muscle)

Outcome

Myoglobin content, muscle fibre diameter, and citrate synthase activitysurrogate

The capacity for oxygen diffusion relative to oxygen demand appears similar in skeletal muscle and the left ventricle, but is higher in papillary muscle.
