Key result
Aortocoronary bypass surgery resulted in similar two-year survival compared to medical management (85% vs 83%), although more than twice as many surgical survivors were pain-free.

Absolute Event Rate: 85% vs 83%
In patients with coronary heart disease, aortocoronary bypass surgery provides superior pain relief at two years compared to medical management, but overall two-year survival is similar between the two strategies.

Surgery associated with better symptom relief but similar survival in this cohort; leaves open selection bias and need for randomized confirmation in modern practice.
McNeer et al. (1974) conducted a cohort in Coronary heart disease (n=781). Aortocoronary bypass surgery vs. Medical management was evaluated on Two-year survival. Aortocoronary bypass surgery resulted in similar two-year survival compared to medical management (85% vs 83%), although more than twice as many surgical survivors were pain-free.
