Use of Strain Imaging to Predict Myocardial Function Recovery after Percutaneous Revascularization of Infarct Related Artery

Abstract

Use of Strain Imaging to Predict Myocardial Function Recovery after Percutaneous Revascularization of Infarct Related Artery Background: Speckle tracking echocardiography is integrated into echocardiographic systems for automated evaluation of left ventricular (LV) function by means of Automated Function Imaging (AFI). This study aimed at evaluating role of strain imaging [AFI & Tissue Velocity Imaging (TVI)] in predicting post-percutaneous coronary intervention (PCI) LV function recovery. Methods: Fifty patients with anterior wall myocardial infarction & impaired LV ejection fraction (LVEF≤45%), were prospectively enrolled. All patients showed positive viability results concerning left anterior descending (LAD) artery territory using low-dose dobutamine stress echocardiography (LDSE) & significant LAD disease for PCI. All patients underwent strain maging using AFI & TVI; at rest, at peak dose of LDSE and 3 months after PCI.
