May inform risk stratification in low-EF CABG; hypothesis-generating and requires prospective validation.
What are the predictors of early occlusion of coronary bypass grafts in patients with coronary artery disease and ejection fraction below 30%?
In patients with severely reduced ejection fraction (<30%) undergoing CABG, the use of autovenous conduits and a lower effective stroke volume index are strong independent predictors of early graft occlusion.
