Why the study?
The study was conducted to review UK national trends in activity and outcomes for coronary artery bypass graft surgery over a 15-year period.
CABG mortality in the UK has consistently improved over 15 years to 1.0% for isolated CABG, despite an aging and higher-risk patient population.
No takes yet. Share an insight, caveat, or question.
UK CABG volumes declined amid rising patient risk yet mortality fell; leaves open questions on PCI substitution and long-term planning.
Ohri et al. (2021) studied this question.
