New blood test may predict bleeding risk after heart surgery
NCT ID NCT07619261
First seen Jun 27, 2026 · Last updated Jun 27, 2026
Summary
This study looks at whether a new test called T-TAS can help predict bleeding after heart surgery. Researchers will take blood samples from 30 adults before, right after, and 24 hours after surgery. They will compare T-TAS results with standard tests and track how much bleeding and blood transfusions each person needs. The goal is to see if T-TAS gives extra useful information to doctors.

Who is studied
Adult patients undergoing elective or urgent cardiac surgery requiring cardiopulmonary bypass at a tertiary academic cardiac surgery center. Participants are recruited prospectively during routine perioperative clinical care and undergo perioperative assessment of flow-based platelet function using the Total Thrombus-formation Analysis System (T-TAS).
