The quality of life of 51 elderly subjects enrolled in cardiac rehabilitation is described to devise strategies for improving QOL as an outcome of a therapeutic regimen. Based on Chrisman and Fowler's Systems-in-Change Model, physical function, social function, and emotional function were assessed via the McMaster Health Index Questionnaire and the Cantril Self-Anchoring Scale during participation in cardiac rehabilitation. The greatest benefit of cardiac rehabilitation to subjects was in physical function, but benefits were also noted in social and emotional function.
