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.

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
EXPERIMENTAL20 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.
Control group
NO INTERVENTION17 patients of the control group receive the standard therapy after bypass surgery.
