Why the study?
Does cardiac troponin I measurement improve the detection of myocardial injury compared to CK/CK-MB ratio in patients undergoing aortic surgery?
Population
59 patients undergoing elective or ruptured abdominal aortic aneurysm repair or elective aortofemoral bypass
Comparison
Cardiac troponin I measurement before operation… vs Creatine kinase myocardial fraction ratio…
Design
Cohort
Follow-up
48 hours after surgery

May support cTnI over CK/CK-MB for perioperative injury detection in aortic surgery; hypothesis-generating, should not yet change practice.
Does cardiac troponin I measurement improve the detection of myocardial injury compared to CK/CK-MB ratio in patients undergoing aortic surgery?
Cardiac troponin I is more sensitive than the CK/CK-MB ratio for detecting perioperative myocardial injury following aortic surgery.
Haggart et al. (2001) studied this question.
