Implication
Highlights the first post-CABG year as critical for graft failure; leaves open whether targeted interventions can reduce early attrition.

Intervention
Coronary artery bypass graft (CABG) surgery
O
Outcome
Angiographically demonstrable changes in bypass status (patency, progression, regression) and their relation to the disease in the native coronary circulation at one year and three yearssurrogate
The majority of CABG graft occlusions occur within the first year after surgery, after which the attrition rate stabilizes at a lower rate.
