Key result
Bilateral IMA grafting is associated with the highest post-CABG CK increase compared to SVG alone.
Why the study?
The influence of using internal mammary artery bypass vessels on changes in seven biochemical assays after coronary artery bypass grafting was unclear.
Does the use of internal mammary artery bypass vessels compared to saphenous vein grafts alone affect postoperative cardiac biomarker concentrations in patients undergoing CABG?
Observational (n=73)
Does the use of internal mammary artery bypass vessels compared to saphenous vein grafts alone affect postoperative cardiac biomarker concentrations in patients undergoing CABG?
The use of bilateral internal mammary arteries for CABG is associated with higher postoperative creatine kinase concentrations compared to saphenous vein grafts alone.
No takes yet. Share an insight, caveat, or question.
Post-CABG CK elevations may vary by conduit; leaves open clinical relevance and need for adjusted thresholds in outcome studies.
Harff et al. (1999) conducted an observational in Coronary artery bypass surgery (n=73). Internal mammary artery bypass (uni- or bilateral) vs. Saphenous vein grafts only was evaluated on Changes in seven biochemical assays after surgery. Bilateral internal mammary artery bypass was associated with the highest post-surgical increase in CK concentration, whereas saphenous vein grafts alone had the lowest increase.
