Early use of cardiac troponin-I and echocardiography imaging for prediction of myocardial infarction size in Wistar rats

A cutoff value of 4.8 ng/mL for cTnI could be used as early as 8 h after MI to accurately identify infarct in this model, whereas echocardiographic images taken 48 h after MI predicted the infarcted area 14 days after MI.
