1 Cold blood cardioplegia reduces the increase in cardiac enzyme levels compared with cold crystalloid cardioplegia in patients undergoing aortic valve replacement for isolated aortic stenosis  Bjørn Braathen, MD, Theis Tønnessen, MD, PhD  The Journal of Thoracic and Cardiovascular Surgery  Volume 139, Issue 4, Pages (April 2010) DOI: /j.jtcvs Copyright © 2010 The American Association for Thoracic Surgery Terms and Conditions

2 Figure 1 Panel A shows maximum (Max) postoperative creatine kinase isoenzyme MB (CK-MB) levels with blood and crystalloid cardioplegia. Panel B shows maximum postoperative troponin-T levels with blood and crystalloid cardioplegia. ∗P < .05 compared with blood cardioplegia.

3 Figure 2 Panel A shows creatine kinase isoenzyme MB (CK-MB) levels preoperatively (Preop.) and 7, 20, 44, and 68hours (h) postoperatively (PO). Panel B shows troponin-T levels preoperatively and 7, 20, 44, and 68hours postoperatively. ∗P < .05 compared with preoperative values.

4 Figure 3 Panels A and B show no correlation between cardiac enzyme levels and crossclamp times in the group of patients receiving cold blood cardioplegia. Panels C and D show a positive correlation between cardiac enzyme levels and crossclamp times in the group of patients receiving cold crystalloid cardioplegia. Dashed lines show 95% confidence and prediction intervals. Max, Maximal; CK-MB, creatine kinase isoenzyme MB.
