Tranexamic Acid, Hemorrhage and Transfusions After Combined Aortic Valve Replacement and Coronary Artery Bypass Surgery.
Norway63 participantsStarted 2006-09
Plain-language summary
In this study we will investigate whether tranexamic acid given as an intravenous bolus injection before start of surgery, followed by a continuous infusion during surgery reduces, perioperative hemostatic activation, and postoperative bleeding and the need for transfusions of blood components in elderly patients undergoing combined aortic valve replacement and coronary artery bypass surgery. Tranexamic acid will be compared with placebo (0.9% sodium chloride) in a randomized and double-blind study design.
The study hypothesis is that tranexamic acid will reduce hemostatic activation and postoperative hemorrhage and the need for blood component transfusions in this group of patients.

Questions worth asking your doctor
Bring these to your next appointment. They're a starting point for a shared conversation — not a sign you qualify or a recommendation to enrol.
1Based on my diagnosis and history, is this trial worth exploring for me — or is there a standard treatment we should try first?
2What does this trial's phase tell us about how much is already known about its safety and benefit?
3What would taking part actually involve for me — visits, tests, time, and travel?
4What are the known and possible risks or side effects I should weigh, and how would they be monitored?
5If this trial isn't the right fit, what other options or trials would you suggest I look into?
Generated to help you prepare — always confirm anything about your own eligibility and care with the study team and your doctor.
Questions for the trial coordinator
The trial coordinator is the person who runs the study day to day. These cover the practical side — logistics, costs, and what taking part would actually mean for your life. The study team confirms whether you meet the criteria; these are questions to ask, not a sign you qualify.
1What does taking part actually involve week to week — how many visits, where, and how long does each one take?
2What costs are covered by the study, and what might I have to pay for myself, including travel, parking, or time off work?
3What happens during screening, and what happens if the study team confirms I don't meet the criteria after those tests?
4Who pays for the scans, blood work, and other tests the trial requires — the study, my insurance, or me?
5How will being in the trial affect my regular care, and will my own doctor stay informed and involved?
6Can I leave the trial at any point if I change my mind, and what would happen to my care if I do?
A starting point for the conversation — always confirm anything about your own eligibility, costs, and care with the study team and your doctor.
