E.2 Objective of the trial |
E.2.1 | Main objective of the trial |
To determine if TXA is superior to placebo for the occurrence of life-threatening, major, and critical organ bleeding, and non-inferior to placebo for the occurrence of major arterial and venous thrombotic events; and to determine the impact of a hypotension-avoidance strategy versus a hypertension-avoidance strategy on the risk of vascular death and major vascular events in patients who are followed for 30 days after noncardiac surgery. |
|
E.2.2 | Secondary objectives of the trial |
To determine the impact of TXA on the following outcomes at 30 days after randomization: a net risk-benefit outcome as a composite of vascular death, and nonfatal life-threatening bleeding, and nonfatal major bleeding, critical organ bleeding, myocardial infarction, stroke, peripheral arterial thrombosis, and symptomatic venous thromboembolism; International Society on Thrombosis and Haemostasis (ISTH) major bleeding; bleeding impacting mortality after noncardiac surgery (BIMS); myocardial injury after noncardiac surgery (MINS); and myocardial infarction.
To determine the impact of a perioperative hypotension-avoidance strategy on all-cause mortality; MINS; and myocardial infarction at 30 days after randomization.

Additionally, patients will be excluded for the BP partial factorial if:
1. Patients with advanced congestive heart failure (New York Heart Association functional class III or IV or left ventricular ejection fraction ≤30%),
2. Patients with untreated brain aneurysm,
3. Patients with previous history of hypertensive related cerebral hemorrhage,
4. Patients undergoing surgery for pheochromocytoma or history of untreated pheochromocytoma,
5. Patients who are hemodynamically unstable or requiring vasopressors or inotropic support before undergoing surgery.
6. Patients with thyrotoxicosis (i.e., severe hyperthyroidism) requiring perioperative beta-blocker therapy. |
