Lithuanian Atletes' Aortic Diameter

Athletes Heart Clinical Trial

Official title: Lithuanian Athletes' Aortic Root Diameter

Status Completed

Clinical Trial Summary

Recent developments in football have seen the sudden death of young football player due to aortic rupture hence reinforcing the controversy of football as a field with substantial risk for sudden cardiac arrest and death. Moreover, there is an argument that aortic dilatation and the subsequent event of thoracic aortic aneurysm may be an occupational disease due to the nature of some vocations (i.e., military and security personnel, blue collar workers, weightlifters, athletes etc.). Of particular importance, there is some evidence that elite athletic training is associated with small but significantly larger aortic root diameter. The purpose of this study was to investigate aortic root adaptation to physical workload and to determine if aortic root's and left ventricle sizes are contingent upon the physical workload

Clinical Trial Description

A preliminary data was collected from a total of 944 subjects in Kaunas Sports Medicine Centre during the recruiting period in 2014-2015. Final data analysis consisted of 151 Caucasian subjects who met the inclusion criteria.

All subjects underwent two-dimensional (2D) transthoracic echocardiography (TTE) procedure. Prior to performing 2D TTE, subjects' arterial blood pressure, heart rate, height, weight, and self-reported physical activity levels were measured.

The Ultrasound system CX50 (Philips Ultrasound, Philips Healthcare, Philips Medical Systems Nederland, USA) - with transducer S5-1 was used in this study. Two physicians performed 2D TTE and averages for all variables of interest were computed. The measurements of aortic root and the left ventricle were drawn upon the guidelines of the American Society of Echocardiography and the European Association of Cardiovascular Imaging.

The maximal diameter of the sinuses of Valsalva was measured at end-diastole, in a strictly perpendicular plane to that of the long axis of the aorta using the edge to leading edge (L-L) convention. The aortic annulus was measured at midsystole from inner edge to inner edge (I-I). This was done in order to obtain the rounder shape and bigger diameter of aortic annulus. ;
