Risk factors for mortality after coronary artery bypass grafting in patients with low left ventricular ejection fraction

Abstract

Concerning the prognosis, patients who undergo CABG would have different risk factors when data from all the enrolled patients or data from patients with LVEF <or= 40% is compared. This is because low LVEF is itself an important risk factor. Regarding the low LVEF patients, the aggressive treatments including correction of mitral regurgitation and resection of aneurysm of the heart wall concomitant with CABG should be taken into account while planning the operative strategy to ensure the perioperative safety and prognosis.
