Outcome Measures
Primary Outcomes (1)
Composite score of any one of the following events occurring 6 months after cardiac surgery: (1) all-cause mortality; (2) myocardial infarction; (3) new onset renal failure requiring dialysis; or (4) new focal neurological deficit (stroke).
Any of all-cause mortality, myocardial infarction, new onset renal failure requiring dialysis, or new focal neurological deficit (stroke).
Within 6 months after cardiac surgery.
Secondary Outcomes (13)
Incidence of each individual component of the primary outcome: all-cause mortality, myocardial infarction, new onset renal failure requiring dialysis, and new focal neurological deficit (stroke).
Within 6 months after cardiac surgery.
Composite and individual all-cause mortality, myocardial infarction, new onset renal failure requiring dialysis, and new focal neurological deficit (stroke).
Up to hospital discharge or after 28 days postoperatively, whichever comes first.
Length of stay in the ICU and hospital.
Up to hospital discharge or after 28 days postoperatively, whichever comes first.
Prolonged low output state.
Up to hospital discharge or after 28 days postoperatively, whichever comes first.
Duration of mechanical ventilation.
Up to hospital discharge or after 28 days postoperatively, whichever comes first.

Study Arms (2)
Restrictive Transfusion Strategy
ACTIVE COMPARATORPatients will receive a RBC transfusion if their Hb concentration is \<75 g/L (\<7.5 g/dL; \<4.7mmol/L) intraoperatively and/or postoperatively.
Liberal Transfusion Strategy
ACTIVE COMPARATORPatients will receive a RBC transfusion if their Hb concentration is \<95 g/L (\<9.5 g/dL; \<5.9mmol/L) intraoperatively, or postoperatively in the ICU; and/or \<85 g/L (\< 8.5 g/dL; \<5.3mmol/L) on the ward.
Interventions
Patients will receive a RBC transfusion if their Hb concentration is \<75 g/L (\<7.5 g/dL; \<4.7mmol/L) intraoperatively and/or postoperatively.
Patients will receive a RBC transfusion if their Hb concentration is \<95 g/L (\<9.5 g/dL; \<5.9mmol/L) intraoperatively, or postoperatively in the ICU; and/or \<85 g/L (\< 8.5 g/dL; \<5.3mmol/L) on the ward.
Eligibility Criteria
You may qualify if:
- ≥18 and ≤65 years of age
- Planned cardiac surgery using cardiopulmonary bypass
- Informed consent obtained
- Preoperative European System for Cardiac Operative Risk Evaluation (EuroSCORE I) of 6 or more
You may not qualify if:
- Patients who refuse participation
