Key result
Early after coronary bypass surgery, exercise duration <420s (RR 1.68), ST depression >1mm (RR 1.90), and LV dysfunction (RR 1.97) independently predicted 1-year death and cardiovascular events.
Why the study?
Do routine non-invasive cardiac investigations performed early after coronary bypass surgery predict clinical endpoints in coronary artery disease patients?
Cohort (n=2,065)
Yes
Do routine non-invasive cardiac investigations performed early after coronary bypass surgery predict clinical endpoints in coronary artery disease patients?
Relative Risk: 1.68 (95% CI 1.13–2.49)
Exercise testing and echocardiography performed early after coronary bypass surgery can identify high-risk patients who may benefit from intensive secondary prevention.

May identify high-risk post-CABG patients; hypothesis-generating and should not yet change practice.
Philippe Sellier (2003) conducted a cohort in Coronary artery disease post-coronary bypass graft surgery (n=2,065). Abnormal non-invasive cardiac investigations (exercise testing, echocardiography) vs. Normal investigation results was evaluated on Combination of all-cause deaths and cardiovascular events requiring hospitalisation (RR 1.68, 95% CI 1.13-2.49). Early after coronary bypass surgery, exercise duration <420s (RR 1.68), ST depression >1mm (RR 1.90), and LV dysfunction (RR 1.97) independently predicted 1-year death and cardiovascular events.
