Relation Between Global Left Ventricular Longitudinal Strain Assessed with Novel Automated Function Imaging and Biplane Left Ventricular Ejection Fraction in Patients with Coronary Artery Disease

Systolic global longitudinal strain assessed by AFI was linearly related to biplane LVEF. In patients with STEMI or heart failure, less strong correlations were observed, suggesting that these 2 parameters reflect different aspects of systolic left ventricular function.
