Coronary artery bypass grafting in octogenarians: a nomogram for predicting all-cause mortality

Abstract Background: The benefits and risks of coronary artery bypass grafting (CABG) in octogenarians remain unclear. This study aimed to identify the predictors of increased risk of all-cause mortality in octogenarian patients after CABG. Methods: We retrospectively analyzed the data of 1636 octogenarians who underwent isolated elective on-pump CABG between 2007 and 2016. The primary endpoint was mortality from any cause. The Kaplan–Meier curve was generated for mortality. A univariate Cox regression was performed for preprocedural and procedural variables. The
