Impaired arterial elastic features is one of the earliest manifestations of atherosclerosis in the vessel wall and associated with the development of cardiovascular disease (CV) and increased mortality and morbidity. We aimed in this study to investigate the mean values of aortic elasticity parameters in a normotensive population with transthoracic echocardiography (TTE) and to evaluate these values in different age groups and their relationship with other risk factors.

This retrospective study included 405 subjects who met the inclusion criteria among 2880 individuals screened between 2000 and 2022. The study population was divided into five groups according to their age. Aortic elasticity parameters (Aortic strain, aortic stiffness index and aortic distensibility) were calculated from the associated formulas by measurements made from the ascending aorta in the parasternal long axis.

In 405 subjects (mean age 42.18±10.39, 54.3% female), the mean aortic strain value was 15.14 ±3.56%, the mean aortic stiffness index was 3.24±1.05, and the mean aortic distensibility was 7.48±2.36 cm2.dyn-1.10-3. It was observed that aortic strain and distensibility values significantly decreased with increasing age groups, while aortic stiffness significantly increased. All three aortic elasticity parameters were strongly correlated to age. In the multivariate linear regression analysis, age was found to be an independent factor for all aortic elasticity parameters.

Aortic elasticity parameters can be evaluated with TEE in daily practice. Comparing these measurements with normal values in similar age groups may help to detect patients with increased CV risk in the early period, regardless of the other risk factors.
