Abstract Background: Acute myocardial infarction is the leading cause of death in North America and Europe. Each year an estimated 785000 Americans will sustain a new myocardial infarction, and another 470000 will have a recurrent myocardial infarction. A new myocardial infarction occur every 25 seconds and new case of death from myocardial infarction occur every minute. Aim of work: To identify the value of 2D speckle tracking derived global longitudinal strain (GLS) in predicting the presence of other significant coronary artery lesions in patients with acute ST elevations anterior myocardial infarction. Patients and Methods: This study was conducted on 60 patients who presented to the coronary care unit (CCU) of Ain Shams university hospital, in the period between March 2017 and September 2017 with first acute anterior STEMI and underwent primary intervention. Results: Echocardiography is assuming a prominent role for evaluating left ventricular function after myocardial infarction; it provides substantial information regarding left ventricular remodeling post acute ST elevation myocardial infarction and the associated significant changes in systolic and diastolic echocardiographic derived indices may affect patients morbidity. Conclusion: In the present study we found new relationship between number of affected segments by using GLS offline at apical four (6 segments), three (5 segments) and two (6 segments), using 17 segments model, and make relation with coronary angiography, the result was, that if segments 10 or less than 10 affected (76%) probability of group A, and if more than 10 probability of group B (60 %), this may be at group b more than one vessel affected lead to multiple teriotoris affected which affect multiple segments, but in group A, only culprit (LAD) single vessel affected so less segments affected. |
