Left Ventricular Global Longitudinal Strain Following Acute ST-Elevation Myocardial Infarction - A Comparison of Primary Coronary Angioplasty and Tenecteplase-Based Pharmacological Reperfusion Strategy.

Objective: In the setting of acute ST-elevation myocardial infarction (STEMI), reperfusion therapy with primary percutaneous coronary intervention (PCI) performed by an experienced team or pharmacological reperfusion with thrombolytic therapy is highly recommended. Standard echocardiographic measurement of the left ventricular ejection fraction (LVEF) is widely used to assess left ventricular global systolic function. This study was designed to compare the assessment of global left ventricular function by standard LVEF and global longitudinal strain (GLS) in the two well-known reperfusion strategies.
