Coronary Artery Disease, Noninvasive Myocardial Work
Conditions
Brief summary
Noninvasive pressure-strain loop (PSL) derived myocardial work (MW) are more sensitive than conventional echocardiographic parameters in quantitative assessment of early myocardial dysfunction. The aim of this study was to assess left ventricular (LV) myocardial function in symptomatic patients with coronary artery disease using the promising method. Methods: Transthoracic echocardiography was performed on patients with angina or equivalent symptoms before coronary angiography. Images were stored and imported into the software for further offline analysis of PSL-based MW. MW analysis were carried out on each patient for global and regional myocardial function assessment.
