Implementation of Global Longitudinal Strain (GLS) in NON-ST Segment Elevation Myocardial Infarction in AL-Yarmook Teaching Hospital

Background: It would be advantageous to develop a noninvasive diagnostic tool that could more reliably distinguish between persons who would benefit from early coronary angioplasty and revascularization and those who would not in non-ST-segment elevation acute coronary syndrome. The LVGLS assessment is painless and may be completed quickly without putting patients through intense activities. Aim of study: To evaluate wall motion abnormality by (GLS) method in comparison with 2D echo and ECG changes. Material and method: A cross sectional study that included 60 patients who admitted to Al-Yarmouk teaching hospital due to new onset of acute coronary syndrome. Result: Mean GLS of patients was -13.61 ± 1.67, and the largest proportion of them were aged 56-60 yrs. regarding echo finding, 80% show hypokinetic motion wall abnormality. Patients with abnormal ECG changes, hypokenisia and low EF had significantly lower mean of GLS (p-value 0.0001, 0.0001, 0.004, respectively). The prediction value of GLS over EF was higher when comparing them according to presence of ECG changes and MWA. Conclusion: GLS is a powerful predictor of left ventricular function and appears to be a better metric than ejection fraction in NSTEMI patients.
