Background: Knowledge on the association between time and cause of death following coronary artery bypass grafting (CABG) in an unselected population is sparse.
Methods: By linking Danish nationwide administrative registries, we identified all patients undergoing first-time isolated CABG (1998-2012). Causes of death were classified as cardiovascular (CV) or non-cardiovascular (non-CV). Patients were followed from the day of surgery until death or December 31, 2012, whichever came first. Cumulative incidence curves were constructed to compare the absolute incidence of CV and non-CV death. Factors associated with all-cause and CV mortality were identified using Cox regression models.
Results: Among 33,980 included patients, 9,713 died during a median follow-up of 6.9 years. Cause of death were classified as CV in 6,071 (62.5%) and non-CV in 3,642 (37.5%) cases. 30-day, 1-year, and 5-year all-cause mortality rates were 2.5%, 5.0%, and 15.4%, respectively, and the corresponding CV mortality rates were 2.2%, 4.0%, and 9.7% (Figure 1). Multivariable Cox regression models yielded the following findings: Age, male gender, urgency of surgery, presence of CV diseases, chronic renal failure, and a history of malignancy were all associated with all-cause mortality. The associations in the model for CV mortality were nearly identical as for all-cause mortality, apart from gender.
Conclusions: In patients undergoing CABG, the majority of both short- and long-term causes of death were cardiovascular.
