Pericardial CTnI shows no accuracy advantage over serum CTnI for Q-wave MI after CABG; leaves open whether alternative biomarkers merit prospective testing.
Is pericardial CTnI more accurate than serum CTnI in predicting perioperative Q-wave MI in patients undergoing elective CABG?
Pericardial CTnI measurements are less useful than serum CTnI for diagnosing perioperative MI after CABG and are not recommended for routine clinical practice.
