Original Article



Increased arterial stiffness is an early sign of endothelial dysfunction. Nevertheless, measures of the elastic properties of the aortic root in patients with type 1 diabetes are still lacking. The aim of this study was to compare aortic root stiffness index in type 1 diabetes and healthy controls.


Ninety-three patients with type 1 diabetes without cardiovascular diseases were recruited and compared to 33 healthy controls. Aortic root elastic properties were estimated by measuring the systolic and diastolic diameters on M-mode acquisition.


None of the subjects showed alterations of either systolic or diastolic echocardiographic parameters. Patients with type 1 diabetes had a very low prevalence of chronic complications and their metabolic control was good. Significantly increased aortic stiffness index was found in type 1 diabetes compared to controls, and the same different pattern was found in men and women. The presence of type 1 diabetes and increased pulse pressure was significantly associated with aortic stiffness index in a multivariate linear analysis.


This study strongly suggests that patients with type 1 diabetes develop aortic root stiffness in the absence of cardiovascular diseases. This alteration may be part of a more generalized arterial dysfunction in type 1 diabetes.
