Why the study?
Is pericardial CTnI measurement more accurate than serum CTnI measurement in predicting perioperative Q-wave myocardial infarction in subjects undergoing elective CABG?
Population
102 subjects undergoing elective coronary artery bypass grafting (CABG)
Comparison
Pericardial cardiac troponin I (CTnI) measurement vs Serum cardiac troponin I (CTnI) measurement
Design
Cohort
Follow-up
first postoperative 24 h

Does not support pericardial CTnI over serum CTnI for perioperative Q-wave MI prediction after CABG; leaves open need for prospective validation.
Is pericardial CTnI measurement more accurate than serum CTnI measurement in predicting perioperative Q-wave myocardial infarction in subjects undergoing elective CABG?
Pericardial CTnI measurements are not more accurate than serum CTnI for diagnosing perioperative MI after CABG and are not recommended for routine clinical practice.
