Relationship between reduced elasticity of extracardiac vessels and left main stem coronary artery disease.

To the Editor, With great interest we read the study on reduced vessel elasticity in left main stem (LMS) coronary artery disease (CAD) by Hadjinikolaou et al., published recently in the Eur Heart J .1 The authors elegantly showed, by careful ex vivo experiments, that the elasticity of extracardiac arteries and veins is impaired in patients with LMS-CAD compared to non-LMS CAD. These findings are …
