With cardiac and cancer cachexia, the
loss of muscle mass is an important determinant of survival (14,
18). Sarcopenia, the progressive loss of muscle mass and function
that occurs with aging, is a widespread syndrome that has a
devastating effect on quality of life and ultimately survival (19).
Progressive sarcopenia is ultimately central to the development
of frailty, an increased likelihood of falls, and impairment of the
ability to perform ADL (19).
