Coronary artery ectasia (CAE) often presents with preserved LVEF, masking the early myocardial impairment that conventional echocardiography fails to detect. This single-center observational study evaluated 90 angiographically confirmed subjects across control, single-vessel CAE, and multi-vessel CAE groups. While standard indices showed preserved systolic function in most patients, two-dimensional speckle-tracking echocardiography (2D STE) revealed significant reductions in global longitudinal, circumferential, and radial strains, indicating subclinical LV dysfunction.

GLS declined progressively with increasing CAE burden, even in cases where routine imaging appeared normal. The findings underscore the clinical utility of 2D STE as an early diagnostic tool for risk stratification and longitudinal monitoring in CAE. To dive deeper into how speckle-tracking reshapes LV assessment in…
