Key result
Left ventricular ejection fraction correlates inversely with the mass of infarcted myocardium on cardiac MRI, demonstrating a 0.5% reduction in ejection fraction for each gram of infarct.

Larger infarct mass may reduce LVEF; leaves open whether quantitative CMR improves post-MI risk stratification.

Does quantitative infarct mass on DCE-MRI predict left ventricular ejection fraction in patients with myocardial infarction?
Effect estimate: r2 = 0.49
Quantitative assessment of infarct mass by DCE-MRI inversely correlates with left ventricular ejection fraction, with each gram of infarcted myocardium predicting a roughly 0.5% reduction in LVEF.
Shriki et al. (2009) conducted an observational in Myocardial infarction (n=30). Infarct mass on delayed contrast-enhanced MRI was evaluated on Left ventricular ejection fraction (r2 = 0.49). Left ventricular ejection fraction correlates inversely with the mass of infarcted myocardium on cardiac MRI, demonstrating a 0.5% reduction in ejection fraction for each gram of infarct.
