Introduction:

The evaluation of quality of life is a health outcome that is commonly associated with the efficacy of treatments derived from patients with coronary artery disease. The literature is unclear regarding the role of cardiac rehabilitation on quality of life in the population undergoing coronary revascularization.

Aim:

To determine if there are differences in perception of health-related quality of life after attending an 8-week cardiac rehabilitation program compared to a 12-week program in people after coronary angioplasty.

Methods:

Randomized controlled clinical trial that included people with coronary angioplasty, who attended a cardiac rehabilitation program, divided in two groups (8 and 12 weeks), who were evaluated through the 8 domains of Short Form-36 Health Survey (SF-36).

Results:

The sample was made up of 17 people, with an average age of 63.1 ± 6.9 years. When comparing the evaluation before and after treatment in each group, statistical differences were found in the physical-functioning and role-physical in 8 weeks group. Comparation between group show differences in role-emotional.

Conclusion:

The results of the present study did not show differences between the global score on health-related quality of life. However, when comparing the two interventions, the 8-week group showed better values on the role-emotional.
