An Australian risk prediction model for 30-day mortality after isolated coronary artery bypass: The AusSCORE

Abstract

OBJECTIVE: Our objective was to identify risk factors associated with 30-day mortality after isolated coronary artery bypass grafting in the Australian context and to develop a preoperative model for 30-day mortality risk prediction. SUMMARY BACKGROUND DATA: Preoperative risk associated with cardiac surgery can be ascertained through a variety of risk prediction models, none of which is specific to the Australian population. Recently, it was shown that the widely used EuroSCORE model validated poorly for an Australian cohort. Hence, a valid model is required to appropriately guide surgeons and patients in assessing preoperative risk. METHODS: Data from the Australasian Society of Cardiac and..
