Why the study?
Does aortocoronary bypass surgery improve survival in patients with left main coronary artery stenosis ≥50% compared to no surgery?
Population

Comparison
Pure aortocoronary bypass graft surgery vs Unoperated (medical management)
Design
Cohort
Follow-up
7 years

Bypass surgery was associated with greater 7-year survival in left main stenosis; leaves open confirmation by randomized trials with contemporary therapy.
Does aortocoronary bypass surgery improve survival in patients with left main coronary artery stenosis ≥50% compared to no surgery?
Aortocoronary bypass surgery significantly improves long-term survival in patients with left main coronary artery stenosis ≥50%, particularly in those with preserved left ventricular function.
Campeau et al. (1978) studied this question.
