Assessment of Right Ventricular Function Using Strain and Strain Rate in Patient with Acute Anterior ST Segment Elevation Myocardial Infarction

摘要

Introduction: Anterior ST-segment elevation myocardial infarctions (STEMI) are those involving the anterior ECG leads of the heart as a result of transmural ischaemia. They can be subdivided according to their extension into anteroseptal and anterolateral infarctions. Objective: The aim of this study is assessment of right ventricular function using strain and strain rate imaging in patients with anterior ST segment elevated myocardial infarction (STEMI). Methods: This prospective study was conducted on 35 patients with anterior ST segment elevated myocardial infarction ( STEMI) who were admitted to ER and CCU department in National Heart Institute from May 2018 to May 2019. Results: Comparison between groups regarding longitudinal strain showed that there is highly statistical ly significant difference between them in lateral wall (all segments), septum (all segments) and global LS of right ventricle. Comparison between studied groups regarding circumfer e ntial strain revealed that there is highly statistical ly significant difference between them in all segments of right ventricle. Conclusions: Strain and strain rate imaging are feasible and reproducible tools in assessment of right ventricular function in patients with anterior ST segment elevated myocardial infarction (STEMI).
