Surgery associated with better survival; leaves open whether CABG improves outcomes versus medical therapy in 3-vessel disease with LVEF >40%.
Does coronary bypass surgery improve long-term survival compared to medical treatment in patients with 3-vessel coronary disease and LVEF >40%?
Coronary bypass surgery significantly improves 5- and 9-year survival and reduces ischemic events compared to medical therapy in patients with 3-vessel coronary disease and preserved ejection fraction.
