OPCAB is associated with similar long-term outcomes to CABG performed on CPB in our institution.
Study context
- Population
- All isolated coronary artery bypass grafting (CABG) at one institution, 2001–2015
- Participants
- 13,226 participants
- Exposure
- Off-pump CABG vs CABG on cardiopulmonary bypass
- OPCABn = 5,882
- Cardiopulmonary bypass (CPB)n = 7,344reference
- Outcome
- Long-term composite of:
- Death
- Revascularisation
- Follow-up
- Median 6.2 years
Methodological detailspropensity-score matched, single-centre
- Propensity-score matched
- Single-centre
