Key Points

Greater reduction in visual ischaemia led to a significant symptom improvement post-CABG.
Patients showed a median decrease in visual ischaemic burden from 42% to 18% after surgery (P<0.001).
Quantitative perfusion metrics did not correlate with symptom improvement, indicating further exploration is needed.
Findings support the importance of visual assessments in assessing post-surgical recovery and myocardial perfusion.
