Introduction: the benefits in relieving symptoms in patients with ischemic heart disease after coronary artery bypass grafting are known but there is little information about how patients perceive their quality of life before and after this intervention. The aim of the study is to determine patients quality of life perception before and after a year of coronary artery bypass grafting. Methods: observational prospective cohort of 202 patients to coordination and election coronary artery bypass grafting procedure was enrolled between 1/8/2012 to 21/08/2013, their ages was between 35 and 70 years, were men 158 (78.2%). Preoperatively and one year after the intervention were self administered prior informed consent two questionnaires: (a) SF-36 which estimates physical and mental health components through a score from 0 to 100 points in 36 items and 8 domains: physical health limitations, physical functioning, bodily pain, general health, mental health, social functioning, emotional limitations and vitality. Item response scales yes / no and Likert. Reliability of the response was determined using Cronbach’s a (> 0.75). (b) DASI of 12 items that estimates the physical functional capacity of patients whose maximum score is 12 points (DASI considered low <10 points). Results: both questionnaires were completed by 199 patients as 3 died in the period. (a) SF-36. Mean score before vs. one year after coronary artery bypass grafting according to the components: Physical Health 51 vs. 84 (p = 0,000), Mental Health 51 vs. 57 (p = 0,07). In all dimensions to Physical Health the scores significantly increased (p = 0,000): physical health limitations: 37 vs. 86, physical functioning: 55 vs. 88, bodily pain: 57 vs. 86, general health: 52 vs. 75; while those of Mental Health the significant increase was in emotional state limitations: 50 vs. 79, and social functioning: 63 vs. 86. Was observed a significant decrease in mental health: 48 vs. 47 and no changes in vitality: 48 vs. 47 (p = 0,954). The item change in health showed a significant increase: 33 vs. 88 (p = 0,000). (b) The mean DASI points before coronary artery bypass grafting was 8,01 ± 2,88, after a year 9,27 ± 2,27 (p = 0,000). DASI <10 before CABG 61,8%, after a year 39,2% (p = 0,00000). Conclusion: the quality of life perception changes significantly in physical health dimension and functional physical capacity after one year to the coronary artery bypass grafting, not in the perception of mental health dimension, especially in vitality.
