Prediction of infarct size using two-dimensional speckle tracking echocardiography in acute myocardial infarction

WOS: 000398109300008 PubMed ID: 28247458 Background: This study aimed to determine the myocardial damage (infarct size provided by cardiac single-photon emission tomography) in early stages of the infarction using longitudinal strain and rotational parameters of the left ventricle. Methods: The study included 66 patients with anterior myocardial infarction (AMI) and 62 patients with inferior myocardial infarction (IMI) who underwent primary percutaneous intervention as well as a control group consisting of 50 healthy subjects. LV rotational parameters based on parasternal short-axis views in basal and apical planes and global longitudinal strain were measured with apical four-chamber, apical two-chamber, and apical long-axis views. Results: There was a significant positive correlation between infarct size and GLPSavg (r=-.55
