Outcome Measures

Primary Outcomes (1)

  • Change in ADAMTS13-Activity over time

    during surgery (at 1and 2 hours after beginning) and within the first 6 days after surgery

Secondary Outcomes (5)

  • Change in ADAMTS13-Antibody over time

    during surgery (at 1and 2 hours after beginning) and within the first 6 days after surgery

  • Change in Platelet count over time

    during surgery (at 1and 2 hours after beginning) and within the first 6 days after surgery

  • time duration of extracorporeal circulation during surgery

    during surgery

  • Amount of intraoperative given fluid replacement

    during surgery

  • Amount of given blood products (red blood cells)

    24 hours

Study Arms (2)

with extracorporeal circulation

Patients undergoing cardiac surgery with the use of an extracorporeal circulation

without extracorporeal circulation

Patients undergoing cardiac surgery without the use of extracorporeal circulation (OPCAB)
