Assessing the environmental impact of coronary artery bypass grafting to decrease its footprint.

Objectives: An urgent transition to environmentally sustainable healthcare is required. The purpose of this study was to identify key areas for environmental impact mitigation for a coronary artery bypass grafting trajectory.

Methods: An ISO14040/44 standardized life cycle assessment was conducted for the functional unit of an individual patient trajectory of elective coronary artery bypass grafting surgery, from operating room admission until intensive care unit discharge.
