Quality of life of patients who undergone myocardial revascularization surgery

a descriptive, cross sectional study, with quantitative approach carried out with 75 patients. The questionnaire WHOQOL-Bref was used to evaluate the quality of life (QOL).

Results:

patients' QOL evaluation presented a moderate result, with need of improvement of all domains. Low income patients had the worst evaluation of QOL in the domain environment (p=0,021), and the ones from Recife/metropolitan area, in the domain social relationship (p=0,021). Smoker (p=0,047), diabetic (p=0,002) and alcohol consumption (p=0,035) patients presented the worst evaluation of the physical domain. Renal patients presented the worst evaluation of QOL in the physical (P=0,037), psychological (p=0,008), social relationship (p=0,006) domains and total score (p=0,009).

Conclusion:

the improvement of QOL depends on the individual's process of behavioral change and the participation of health professionals is essential to formulate strategies to approach these patients, especially concerning health education.
