Key result
Coronary endarterectomy during CABG links to higher short-term mortality and morbidity, partly reflecting baseline severity.
Why the study?
Does coronary artery bypass grafting with coronary endarterectomy affect short-term mortality and morbidity compared to isolated bypass grafting?
Does coronary artery bypass grafting with coronary endarterectomy affect short-term mortality and morbidity compared to isolated bypass grafting?
While CABG with coronary endarterectomy carries higher short-term risks than isolated CABG, this excess risk may reflect baseline disease severity rather than the procedure itself, providing benchmarking data for clinical counseling.

Informs benchmarking for counseling in complex CABG with endarterectomy; extends evidence by implicating baseline severity in observed risks.
Coronary artery bypass grafting with coronary endarterectomy is associated with higher short-term mortality and morbidity compared with isolated bypass grafting; however, confounder-adjusted analyses suggest this excess risk is partly attributable to greater baseline disease severity rather than an independent procedural effect. The scarcity of data and absence of randomized evidence preclude definitive causal conclusions. These findings provide benchmarking data for counselling when endarterectomy is necessary to achieve complete revascularisation.
