Association Between Perioperative Platelet Function and Major Adverse Perioperative Events

Canada250 participantsStarted 2009-03

Plain-language summary

This study will examine the degree of blood thinning (platelet function) in patients coming for non-cardiac surgery on antiplatelet agents using platelet function tests called thromboelastography (TEG) and platelet mapping assay (PMA) and major cardiac complications that occur any time after surgery (perioperative).

AI-rewrites the medical criteria so a patient or caregiver can understand them. Always confirm with the trial site.

Inclusion Criteria: * patients between ages 30-85 years old, receiving post-PCI aspirin and/or clopidogrel therapy * patients undergoing non-ambulatory, NCS * patients will have received a bare metal coronary stent within the last 12 months or a drug eluting stent at any time prior to their NCS * the type of surgery has to be such that there are no contra-indictions to remain on an anti-platelet agent * surgeon must agree to keep the patient on at least one anti-platelet agent during the perioperative period Exclusion Criteria: * clotting abnormalities * drugs affecting platelet function other than aspirin or clopidogrel * moderate renal impairment * liver dysfunction with co-existing thrombocytopenia

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.
