Comparison of quality of life after repeat versus initial coronary artery bypass grafting

One-year health status improvements in 62 patients with previous coronary artery bypass grafting (CABG) were compared with those of 628 patients undergoing initial CABG using the Seattle Angina Questionnaire (SAQ). Adjusted analyses revealed that repeat CABG conferred similar 1-year improvements in health status compared with patients undergoing a first CABG (changes in SAQ Physical Limitation score [SAQ-PL: repeat CABG 25 ± 27 vs first CABG 20 ± 27; p = 0.30], Quality of Life score [SAQ-QoL: 34 ± 24 vs 35 ± 5; p = 0.87], and Angina Frequency score (SAQ-AF: 35 ± 40 vs 25 ± 24; p = 0.03]).
