[Health-related quality of life before and six months after coronary artery bypass graft surgery].

Coronary artery bypass grafting (CABG) surgery aims at offering a better health-related quality of life (HRQL), relieving symptoms and increasing survival. The objectives were to compare HRQL before CABG and six months after it and to evaluate its relation concerning participants' age, sex, schooling and marital status. Descriptive and longitudinal study which used the SF-36 to evaluate HRQL. Among the 54 subjects, 53,7% were men, 66,7% of them were married, their average age was of 57,3 +/- 9,7 and their schooling of 5,7 +/- 4. After CABG, the scores of the domains of the SF-36 varied from 62 to 74,2 being the previous interval from 17,1 to 58,1. Men showed a better evaluation towards HRQL before and after CABG than women, but the differences were only statistically significant for General Health and Bodily pain. No association between HRQL, schooling and marital status was stated. In conclusion, the CABG improved participants' HRQL.
