NCT04745468

Brief Summary

The CABY1 study is conducted open, controlled, randomized and monocentric. The efficacy and tolerability of CRP apheresis in patients undergoing elective primary coronary bypass surgery is investigated.

Outcome Measures

Primary Outcomes (1)

  • Tissue damage of the heart

    Daily determination of the concentration of the biomarker Troponin I (hsTnI)

    Every 24 hours for up to 96 hours after bypass surgery

Secondary Outcomes (7)

  • Safety of CRP apheresis

    24 hours after each apheresis

  • Cardiac events

    Until the patient is discharged from the hospital, an average of 7 days

  • Tissue damage of the heart with Procalcitonin

    Every 24 hours for 72 hours after bypass surgery

  • Tissue damage of the heart with CK-MB

    Every 24 hours for 72 hours after bypass surgery

  • Tissue damage of the heart with Myoglobin

    Every 24 hours for 72 hours after bypass surgery

  • +2 more secondary outcomes

Study Arms (2)

Apheresis Group

EXPERIMENTAL

20 patients receive 2 apheresis treatments at intervals of 24 ± 12 h (additionally to the standard therapy after bypass surgery). The first treatment starts within 24 h postoperatively. If the CRP concentration increases to at least 30 mg/L 6-18 h after the end of the second treatment, a third treatment is performed. For each treatment the 1 - 2.5-fold plasma void is processed. The duration of each treatment is 4-6 h.

Device: CRP apheresis

Control group

NO INTERVENTION

17 patients of the control group receive the standard therapy after bypass surgery.

Interventions

Selective CRP apheresis by use of the PentraSorb-CRP adsorber

Apheresis Group
