Does two-dimensional speckle tracking imaging have diagnostic value for evaluating left ventricular systolic function in patients with CMD and obstructive CAD?
Two-dimensional speckle tracking imaging, specifically GLS and stratified LS, has diagnostic value for identifying early left ventricular systolic dysfunction in patients with coronary microvascular dysfunction.
Early left ventricular systolic dysfunction was found in patients with CMD and patients with obstructive CAD, with similar degree. CFR is an independent influencing factor of GLS. GLS and stratified LS have certain diagnostic value for CMD.
