Higher muscle mass associated with lower mortality risk in people with heart disease

Researchers from the David Geffen School of Medicine at UCLA found that cardiovascular disease patients who have high muscle mass and low fat mass have a lower mortality risk than those with other body compositions. The findings also suggest that regardless of a person’s level of fat mass, a higher level of muscle mass helps reduce the risk of death.

This findings indicate the importance of assessing body composition as a way to help predict cardiovascular and total mortality in people with cardiovascular disease.
