Key result
Coronary artery bypass grafting was associated with significant improvements in quality of life 10 years post-operation compared to baseline (NHP mean improvement -4.2; P<0.0001).
Why the study?
Does coronary artery bypass grafting improve quality of life over 10 years in patients without previous CABG or simultaneous valve surgery?

Supports long-term QoL evaluation after CABG in eligible patients; leaves open need for randomized confirmation.

Does coronary artery bypass grafting improve quality of life over 10 years in patients without previous CABG or simultaneous valve surgery?
Mean Difference: -4.2
p-value: p=<0.0001
CABG provides significant long-term improvements in quality of life up to 10 years post-surgery, although some deterioration occurs between 5 and 10 years.
Herlitz et al. (2003) conducted a cohort in Coronary artery disease requiring CABG. Coronary artery bypass grafting (CABG) vs. Preoperative baseline was evaluated on Quality of life measured with Nottingham health profile (NHP) (MD -4.2, p=<0.0001). Coronary artery bypass grafting was associated with significant improvements in quality of life 10 years post-operation compared to baseline (NHP mean improvement -4.2; P<0.0001).
