Abstract
BACKGROUND: Three-dimensional (3D) speckle tracking echocardiography (STE) after ST-elevation acute myocardial infarction (STEMI) is associated with left ventricular (LV) remodeling and 1-year prognosis. This study investigated the clinical significance of 3D-STE in predicting the long-term prognosis of patients with STEMI. METHODS AND RESULTS: =132.2, P<0.0001). When combined with 3D-GCS >-18.3, patients with higher values of 3D-GLS and 3D-GCS were found to be at extremely high risk for MACE. CONCLUSIONS: Global strain measured by 3D-STE immediately after the onset of STEMI is a clinically significant predictor of 10-year prognosis.
