Survival of coronary artery disease patients with stable pain and normal left ventricular function treated medically or surgically at Duke University.
Why the study?
Does surgical treatment improve survival compared to medical treatment in patients with stable CAD and normal left ventricular function?

Implication
Surgery was not associated with improved survival versus medical therapy in stable CAD with normal LV function; leaves open benefit in three-vessel disease for randomized trials.
Structured PICO
Does surgical treatment improve survival compared to medical treatment in patients with stable CAD and normal left ventricular function?
P
Population
Patients with one-, two- or three-vessel coronary disease (CAD) (≥75% or ≥50% vessel occlusion), stable pain, and normal left ventricular function observed at Duke University Medical Center over an 11-year period

Outcome
Survival rateshard clinical
In patients with stable CAD and normal left ventricular function, surgical treatment did not statistically significantly improve survival compared to medical therapy, although a non-significant trend favoring surgery was observed in three-vessel disease.
