Primary Outcome Measures

Name	Time	Method
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).	Within 6 months after cardiac surgery.	Any of all-cause mortality, myocardial infarction, new onset renal failure requiring dialysis, or new focal neurological deficit (stroke).

Secondary Outcome Measures

Name	Time	Method
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.	Composite and individual incidence of all-cause mortality, myocardial infarction, new onset renal failure requiring dialysis, and new focal neurological deficit (stroke).
Length of stay in the ICU and hospital.	Up to hospital discharge or after 28 days postoperatively, whichever comes first.	Length of stay in the ICU and hospital in days.
Acute kidney injury.	Up to hospital discharge or after 28 days postoperatively, whichever comes first.	Defined by the Kidney Disease Improving Global Outcomes (KDIGO) clinical practice guideline - a 50% increase in serum creatinine within 1 week or a 26.5 mmol/L increase within 48 hours.
Duration of mechanical ventilation.	Up to hospital discharge or after 28 days postoperatively, whichever comes first.	Time on mechanical ventilation.
Incidence of infection.	Up to hospital discharge or after 28 days postoperatively, whichever comes first.	Defined as septic shock with positive blood cultures; pneumonia defined as autopsy diagnosis or roentgenographic infiltrate and at least two out of three of the following criteria: fever, leukocytosis, and positive sputum culture; and/or deep sternal or leg wound infection requiring intravenous antibiotics and/or surgical debridement.
Prolonged low output state.	Up to hospital discharge or after 28 days postoperatively, whichever comes first.	Defined as the need for two or more inotropes for 24 hours or more, intra-aortic balloon pump or ventricular assist device postoperatively.
Delirium.	Up to hospital discharge or after 28 days postoperatively, whichever comes first.	Confusion Assessment Method (CAM) or CAM-ICU (even on 1 occasion), or Intensive Care Delirium Screening Checklist (ICDSC) \> 3, or 3D-CAM, or 4AT ≥4, or more than one dose of haloperidol or similar antipsychotic drug, or documented delirium by neurologist or neurosurgeon or psychiatrist consultation.
Hospital visits.	Within 6 months after cardiac surgery.	Hospitalization and/or emergency visits and coronary revascularization after index procedure.
Incidence of encephalopathy.	Up to hospital discharge or after 28 days postoperatively, whichever comes first.	Unexpected delayed awakening or severely altered mental status (unconscious despite no sedative medication for more than 5 days), or encephalopathy documented by neurologist or neurosurgeon or psychiatrist consultation.
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.	Incidence of all-cause mortality, myocardial infarction, new onset renal failure requiring dialysis, and new focal neurological deficit (stroke).
Incidence of gut infarction.	Up to hospital discharge or after 28 days postoperatively, whichever comes first.	Confirmed by imaging (e.g. angiography), autopsy, or through surgical means.
Incidence of seizures.	Up to hospital discharge or after 28 days postoperatively, whichever comes first.	Generalized or focal tonic-clonic movements consistent with seizure; or electroencephalogram demonstrating epileptiform discharges; or diagnosis of seizures by neurologist or neurosurgeon consultation.
Transfusion requirements.	Up to hospital discharge or after 28 days postoperatively, whichever comes first.	The proportion of patients transfused and the number of blood products utilized (RBCs, plasma, platelets).
