Long-Term Survival Advantage of Total Arterial Revascularization in Elderly Patients Following Coronary Artery Bypass Grafting
Authors' conclusion
TAR improves long-term survival in both elderly and younger patients.
Study context
- Population
- Patients undergoing primary isolated CABG with at least 2 grafts, 2001–2020, binational cardiac surgery registry
- Participants
- 59,641 patients
- Exposure
- Total arterial revascularization (TAR) vs non-TAR grafting in elderly and younger patients
- Outcome
- Long-term all-cause mortality
Methodological detailsbinational registry, inverse probability treatment weighting
- Binational registry
- Inverse probability treatment weighting
Main finding
As reported in the abstract
Long-term survival, by age group
TAR vs Non-TARHazard ratio (95% CI)P value
Elderly (≥70 years)
0.87(0.81–0.92)
P < 0.001Younger (<70 years)
0.80(0.73–0.88)
P < 0.001Observational data: associations, not effects.
Further findings
Survival, non-TAR split into multiple vs single arterial grafting
- Survival hierarchy: highest with TAR, then non-TAR-multiple arterial grafting, lowest with non-TAR-single arterial grafting
