- Primary Outcome Measures
Name Time Method Main Objective: i. Should low-dose aspirin be continued up until the day of Coronary Artery Bypass Graft(CABG) surgery? ii. Should tranexamic acid be used for all at-risk CABG surgery?;Secondary Objective: Primary Endpoint; A composite endpoint including 30-day mortality or major ischaemic morbidity (myocardial infarction, stroke, pulmonary embolism, renal failure, bowel infarction) Secondary Endpoints; (i) 30-day mortality (ii) Ischaemic complications • Myocardial infarction • Stroke • Renal failure • Pulmonary embolism • Bowel infarction (iii) Bleeding complications • Major haemorrhage (re-operation for bleeding) • Cardiac tamponade • Number of transfused blood product units;Primary end point(s): The primary outcome is all cause mortality at 30 days following surgery.
