Advances in the Application of Non-Invasive Myocardial Work in Assessing Left Ventricular Function and Prognosis After Percutaneous Coronary Intervention in Patients with Acute Myocardial Infarction

Timely assessment of left ventricular function, prognosis prediction, and subsequent adjustment of clinical treatment strategies are crucial for improving clinical outcomes in patients with acute myocardial infarction (AMI) undergoing percutaneous coronary intervention (PCI). Traditional assessment methods, such as cardiac magnetic resonance imaging and conventional echocardiography, have limitations, including high cost, time consumption, or insufficient sensitivity. Non-invasive Myocardial Work (MW) technology, by combining speckle tracking and left ventricular pressure-strain loops, dynamically quantifies myocardial mechanical properties, providing a novel non-invasive approach for assessing AMI patients after PCI. This article analyzes recent literature, elaborates on the principles of MW technology and its application in left ventricular function evaluation, dynamic monitoring of postoperative myocardial function, and guiding clinical treatment decisions after PCI in AMI patients. It also discusses the current limitations of MW technology and its future prospects, aiming to explore the clinical value of MW technology in the assessment of AMI patients after PCI.
