Coronary artery calcium burden and metabolic indices in relation to arteriovenous fistula functionality and post-functionality failure

Background

Autogenous arteriovenous fistula (AVF) is the preferred haemodialysis access, but functionality failure and subsequent post-functionality AVF failure remain common. Whether coronary artery calcium (CAC), a marker of systemic vascular calcification, is associated with either outcome is unclear; competing events are frequently ignored.
