Key result
A simplified bedside risk score based on preprocedural factors accurately predicted long-term mortality up to 7 years after coronary artery bypass graft surgery (overall 7-year mortality 24.2%).

Does a simplified bedside risk score using preprocedural risk factors accurately predict long-term mortality in patients undergoing isolated CABG surgery?
Cohort (n=8,597)
Yes
Does a simplified bedside risk score using preprocedural risk factors accurately predict long-term mortality in patients undergoing isolated CABG surgery?
A newly developed simplified bedside risk score using 13 preprocedural clinical variables accurately predicts 1- to 7-year mortality after isolated CABG surgery.

May inform preoperative counseling in CABG; extends short-term models to 7 years but requires external validation before practice change.
Wu et al. (2012) conducted a cohort in Coronary artery bypass graft surgery (n=8,597). Preprocedural risk factors was evaluated on Long-term mortality (years 1, 3, 5, and 7). A simplified bedside risk score based on preprocedural factors accurately predicted long-term mortality up to 7 years after coronary artery bypass graft surgery (overall 7-year mortality 24.2%).
