Abstract

Objectives: To evaluate the left ventricular global longitudinal strain (LVGLS) in patients with acute myocardial infarction using the speckle tracking echocardiography and the relationship between LVGLS with some clinical and subclinical characteristics in patients with acute myocardial infarction. Methods: A cross-sectional descriptive study, analysis, and convenient sampling on 44 patients with acute myocardial infarction were diagnosed according to the Fourth Global Consensus 2018 and treated at Cardiovascular Center, Military Hospital 103, performed speckle tracking echocardiography and analyzed the results using QLAB version 9.0 software. Results: LVGLS in the study group (%) ( ± SD) was -10.8 ± 3.9. Reduced LVGLS measured by STE was associated with left ventricular dyskinesia zones on two dimensional echocardiography (p < 0.05). GLS proportionally correlated with the heart rate (r = 0.41; p < 0.01) and left ejection fraction measured by the Simpson Biplane method (r = 0.36; p < 0.05). Conclusion: Reduced LVGLS measured by STE was associated with left ventricular dyskinesia zones on two dimensional echocardiography (p < 0.05). The LVGLS proportionally correlated with the heart rate and left ejection fraction measured by the Simpson Biplane method.
