the degradative changes of the myofilament apparatus of the heart cells and the specific changes in mitochondrial ultrastructure ( including swelling , septation and apparent division ) are characteristic of the cellular damage of both the dystrophic skeletal muscle and of normal cardiac muscle in which [ ca ] i has been experimentally raised , confirming the suggestions that ( i ) the same gene is responsible for the myopathy of skeletal and cardiac muscle in animal dystrophy and ( ii ) that changes in [ ca ] i are implicated in the degradative changes of muscle cells .
