Detaillierte Beschreibung
Coronary artery bypass graft surgery performed with cardiopulmonary bypass is associated with activation of systemic inflammatory pathways. Contact of blood with the extracorporeal circuit, surgical trauma, ischemia-reperfusion injury, and perioperative factors may contribute to this response. Minimally invasive extracorporeal circulation systems are designed to reduce blood-air contact, circuit surface area, and hemodilution and may therefore attenuate the inflammatory response compared with conventional cardiopulmonary bypass.
In this prospective observational study, patients undergoing elective coronary artery bypass graft surgery will be evaluated according to whether minimally invasive extracorporeal circulation or conventional extracorporeal circulation is used during surgery. No treatment assignment will be made by the study protocol.
Inflammatory response will be assessed using neutrophil-to-lymphocyte ratio, platelet-to-lymphocyte ratio, and systemic immune-inflammation index calculated from routinely obtained laboratory measurements. Measurements will be evaluated preoperatively, at 6 hours after surgery, at 24 hours after surgery, and at hospital discharge. Perioperative variables and postoperative clinical outcomes will also be recorded for comparison between the two groups.

Zeitfenster |
|---|---|---|
|
Neutrophil-to-Lymphocyte Ratio (NLR)
Zeitfenster: Preoperative baseline, 6 hours after surgery, 24 hours after surgery, and on the morning of hospital discharge, an average of 6 days after surgery.
|
NLR will be calculated from routine complete blood count values by dividing the absolute neutrophil count by the absolute lymphocyte count.
Values will be compared between the MIECC and conventional cardiopulmonary bypass groups.
|
Preoperative baseline, 6 hours after surgery, 24 hours after surgery, and on the morning of hospital discharge, an average of 6 days after surgery.
|
|
Platelet-to-Lymphocyte Ratio (PLR)
Zeitfenster: Preoperative baseline, 6 hours after surgery, 24 hours after surgery, and on the morning of hospital discharge, an average of 6 days after surgery.
|
PLR will be calculated from routine complete blood count values by dividing the platelet count by the absolute lymphocyte count.
Values will be compared between the MIECC and conventional cardiopulmonary bypass groups.
|
Preoperative baseline, 6 hours after surgery, 24 hours after surgery, and on the morning of hospital discharge, an average of 6 days after surgery.
|
|
Systemic Immune-Inflammation Index (SII)
Zeitfenster: Preoperative baseline, 6 hours after surgery, 24 hours after surgery, and on the morning of hospital discharge, an average of 6 days after surgery.
|
SII will be calculated as neutrophil count × platelet count / lymphocyte count using routine complete blood count values.
Values will be compared between the MIECC and conventional cardiopulmonary bypass groups.
|
Preoperative baseline, 6 hours after surgery, 24 hours after surgery, and on the morning of hospital discharge, an average of 6 days after surgery.
