Does acute native T1 mapping differentiate reversible versus irreversible myocardial injury and predict left ventricular remodeling in patients with ST-segment-elevation myocardial infarction?
Effect estimate: Prediction accuracy 96.7% (95% CI 82.8% to 99.9%)
Acute native T1 mapping accurately differentiates reversible from irreversible myocardial injury and strongly predicts 6-month left ventricular remodeling in STEMI patients.
Liu et al. (2017) conducted an observational in ST-segment-elevation myocardial infarction (n=60). Acute native T1 mapping vs. Late gadolinium enhancement was evaluated on Differentiation of oedematous versus necrotic myocardium (Prediction accuracy 96.7%, 95% CI 82.8% to 99.9%). Acute native T1 mapping differentiated reversible from irreversible myocardial injury with a prediction accuracy of 96.7% (95% CI, 82.8% to 99.9%).
