Key result
Critical LMCA stenosis fails to independently increase early post-CABG mortality.
Why the study?
The role of critical left main coronary artery stenosis as a risk factor for early mortality after coronary artery bypass surgery was unclear.
Is critical left main coronary artery stenosis an independent risk factor for early mortality in patients undergoing coronary artery bypass surgery?
Comparison
Patients with critical LMCA stenosis vs patients without LMCA disease but with double- or triple-vessel disease

Critical LMCA disease does not independently raise early CABG mortality; leaves open its role in modern risk models.

Is critical left main coronary artery stenosis an independent risk factor for early mortality in patients undergoing coronary artery bypass surgery?
Critical left main coronary artery disease is not an independent risk factor for early mortality after coronary artery bypass surgery, whereas emergent presentation, diabetes, and poor LV function significantly increase risk.
Gol et al. (2000) conducted a cohort in Coronary Artery Disease (n=1,566). Critical left main coronary artery (LMCA) stenosis vs. Double- or triple-vessel disease without LMCA stenosis was evaluated on Early mortality. Critical left main coronary artery stenosis was not an independent risk factor for early mortality after coronary artery bypass surgery, whereas emergent operations (OR 5.09) and diabetes (OR 3.66) were.
