Left Ventricular Systolic Function Assessed by Speckle Tracking Echocardiography in Athletes with and without Left Ventricle Hypertrophy The aim of this study was selected parameters for the elongation and rotation of the left ventricle (the basal rotation index (BR), the basal scope limit index (BCS) and the global longitudinal strain (GLS) of the left ventricle) in male athletes with physiological cardiac hypertrophy (LVH group)as well as athletes (non-LVH group) and non-athletes without hypertrophy (control group, CG) to evaluate. They were evaluated before and after a stress test by means of transthoracic echocardiography and Speckle tracking echocardiography.The LVH group showed a lower BR in peace than the non-LVH group and the CG. The physical effort had no influence on the BR, and this effect did not differ between the groups. There was a combined influence of LVH and physical effort on BR and BCS, but no significant differences in BCS and GLS at rest between the groups. A higher BCS and a lower GLS after loading in the LVH group were detected compared to the CG. The left ventricular basal rotation as well as the longitudinal and peripheral loads showed a lower difference between rest and strain in subjects with significant myocarde hypertrophy.
In summary, the results obtained may indicate that the echocardiographic assessment of the basal rotation and the peripheral load of the left ventricle in the prediction of heart disease caused by physical effort caused by physiological and pathological cardiac hypertrophy.
