Multimodal Echocardiography for Diagnostic Value of Type 2 Diabetes Mellitus Complicated with Left Anterior Descending Artery Stenosis: A Retrospective Case-Control Study

Multimodal echocardiography, especially 2D-STE and CA-USI, provides a more accurate assessment of LAD stenosis in T2DM patients than conventional 2DE. Specifically, for detecting LAD stenosis ≥50%, 2D-STE achieved an AUC of 0.818, sensitivity of 0.760, and specificity of 0.875; CA-USI yielded an AUC of 0.849, sensitivity of 0.802, and specificity of 0.895; while 2DE had an AUC of 0.583, sensitivity of 0.239, and specificity of 0.927. These findings support the clinical utility of 2D-STE and CA-USI for comprehensive coronary evaluation in patients with T2DM.
