Mild aortic enlargement may be a consequence of intense training, although even the definition of aortic dilatation, particularly in athletes and tall athletes, is sometimes challenging. It is therefore essential to early identify competitive athletes with aortic dilatation to manage this condition appropriately. Purpose This study aimed to test a new parameter for the definition of aortic dilatation in competitive athletes, assessing the balancing cardiac remodelling in athletes through the ratio between the aortic diameter and left ventricular (LV) diameter. Methods Competitive athletes were compared with sedentary subjects and with patients with known aortic dilatation. 1901 subjects who underwent echocardiography from 2019 to 2022 were retrospectively enrolled: 993 athletes (74% males, mean age 26±7 years), 410 sedentary (74.1% males, mean age 29±11 years) and 498 patients with aortic dilatation (74.3% males, mean age 56±7 years). Results Patients with aortic dilatation had both an absolute (39.2±2.4 mm) and indexed (19.4±2.2 mm/m2) aortic diameter larger than athletes (30.6±3.2 mm; 16.1±1.5 mm/m2) and sedentary subjects ( 30.5±3.1 mm; 16.5±1.6 mm/m2), with no statistically significant differences between athletes and sedentary subjects. The ratio between the aortic diameter and LV end-diastolic diameter was lower in athletes (0.59 ± 0.06), compared to sedentary subjects (0.65 ± 0.05) and to patients with aortic dilatation (0.81 ± 0.06). The latter had a significantly higher value than the remaining groups (p Conclusions This study tested a new echocardiographic parameter for the definition of an aortic dilatation in competitive athletes. The ratio between aortic diameter and LV end-diastolic diameter, with a cut off of 0.71, demonstrated a good sensitivity and specificity to differentiate between physiological and pathological remodelling of the aorta. |
