Echocardiography-Based Structural and Functional Features and Indicators of the Left Ventricular Deformation in Athletes

Aim. To determine the structural and functional characteristics of the myocardium in young people with different levels of physical activity (PA).Material and methods. The study included 108 young people without cardiovascular diseases. Seventy-two people were professional endurance athletes (Group A) and 36 were non-athletes (Group non-A). Anthropometric data were evaluated. Transthoracic echocardiography and assessment of left ventricular (LV) longitudinal, radial and circumferential strain, as well as LV twisting, were performed. PA level in non-A group was determined using International Physical Activity Questionnaire (IPAQ).Results. PA level <600 MET-min/week was revealed in 22,3% of participants, moderate PA (from 600 to 1500 MET-min/week) — in 41,7%, and high (3000 MET-min/week) — in 36% of participants of inactive, moderately active and highly active subgroups, respectively. Group A daily PA level was ~15000 MET-min/week. In non-A group, there were no significant differences in echocardiographic parameters in subgroups with different PA levels. Significant differences with group A were revealed. LV diastolic function was within the normal range in all subgroups. The E/A ratio was higher in subgroups with higher PA (maximum in subgroup A). Significant differences were observed between inactive (p=0,027) and athletes/moderately active (p=0,017) subgroups. Longitudinal, radial and circular strain characteristics did not differ in A and non-A groups and were within normal range.Conclusion. In young people without cardiovascular diseases with PA ranges from extremely low to those recommended by WHO, the structural and functional myocardial characteristics were within age normal range and significantly differed from those of professional athletes. In professional athletes, these parameters also remained within the age normal range. Myocardial strain characteristics were within the normal range in all participants

Features of longitudinal left ventricular (LV) myocardial deformation in female patients of reproductive age with undifferentiated connective tissue dysplasia (UCTD) have not been specifically studied before.Aim. To study the features of longitudinal LV myocardial deformation using speckle tracking echocardiography in female patients of reproductive age with UCTD.Material and Methods. A noninvasive assessment of systolic LV myocardial deformation in the longitudinal direction using echocardiography was performed in 20 young adult female patients with UCTD (the average age was 23.5 ± 2.6 years). A control group composed of 34 apparently healthy women of comparable age (the average age was 24.8 ± 2.4 years) with no signs of UCTD were examined.Results. The indices of longitudinal systolic myocardial deformation in female patients with UCTD practically did not differ from the control group. Significant differences were found only for the median segment: excessive shortening of the interventricular septum and a decrease in deformation in the lateral wall of the left ventricle. Segments 8–10 (mid anteroseptal, mid inferolateral, and mid inferior) and all apical LV segments (13–17: apical anterior, apical septal, apical inferior, and apical lateral) were subjected to maximum deformation, p < 0.05.Conclusions. In patients of reproductive age with UCTD, a significant decrease in global longitudinal systolic LV deformity was recorded in the basal segment of the interventricular septum and the apical segment of the anterior LV wall. Segments 8–10 (median anterior-septum, median inferior-septum, and lower) and all apical LV segments (13–17: apical anterior, apical septum, apical lower, and apical lateral) were subjected to the greatest deformation in the examined patients.
