Megjegyzések:Background: Earlier results suggest the role of speckle-tracking echocardiography (STE)-derived left ventricular (LV) strains in screening and could help better understanding of adaptation to exercise. The present retrospective cohort study aimed to investigate three-dimensional STE-derived LV strains representing its deformation in athletes playing sports with high dynamics with different grades of static components of their training. Methods. The study consisted of 67 athletes (mean age: 23.6±6.4 years, 39 males). This group of athletes was further divided into the following groups: Group C.I. (high dynamic/low static) (n=12), Group C.II. (high dynamic/moderate static) (n=22) and Group C.III. (high dynamic/high static) (n=33). The control group comprised 83 age- and gender-matched non-athletic healthy volunteers (mean age: 23.6±3.2 years, 50 males). Results: Global LV longitudinal strain (LS) representing LV lengthening or shortening (-18.5%±3.0% vs. -16.3%±2.3%, P<0.05), LV circumferential strain (CS) representing LV widening or narrowing (-29.9%±5.2% vs. -28.1%±4.8%, P<0.05) and LV area strain (AS; combination of LS and CS; -43.7%±5.4% vs. -40.9%±4.8%, P<0.05) were increased in elite athletes as compared to those of non-athlete controls. All apical LV strains proved to be increased in all athletes with enhanced basal radial strain (RS, representing LV thickening and thinning) and LS and midventricular LS, AS and 3D strain (3DS, combination of RS, LS and CS). Conclusions: Increased LV-LS, LV-CS and LV-AS represents enhanced LV deformation in longitudinal and circumferential directions in athletes playing sports with high dynamics. This enhancement is not related to the grade of the static component of training. Some regional differences in LV strains could be detected.

Megjegyzések:Background Physiologic remodeling due to repetitive overload induced by exercise training is a known feature in the athletes' heart including significant changes in left ventricular (LV) deformation mechanics. The aim of the present study was to investigate three-dimensional speckle-tracking echocardiography- (3DSTE-)derived LV strains in elite athletes doing high dynamic sports with different grades of static components of their training. Methods The athlete group comprised 67 subjects (mean age: 23.6?6.4 years, 50 men). The following groups were created regarding their physical activity: Group C. I. (high dynamic/low static) (n=12, mean age: 23.1?4.0 years, Group C. II. (high dynamic/moderate static) (n=22, mean age: 24.8?7.8 years) and Group C. III. (high dynamic/high static) (n=33, mean age: 23.0?6.1 years). Their results were compared to 83 age- and gender-matched non-athletic healthy controls (mean age: 23.6?3.2 years, 50 men). All athletes and non-athletes underwent a complete two-dimensional Doppler echocardiography examination with 3DSTE. Results None of the healthy subjects or athletes had any known cardiovascular risk factors or received drugs and ECG showed no significant alterations. Athletes spent 10.8?3.3 years, 10.1?5.9 years and 6.9?4.2 years in elite sport in Groups C. I., C. II. and C. III., respectively. No significant differences could be seen in the ratio of athletes being in an actual race period between Groups C. I., C. II. and C. III. [n=3 (25%), n=11 (50%) and n=11 (32%), respectively]. Enlarged LV dimensions and thickened posterior wall and interventricular septum were found in all athletes compared to the non-athlete healthy control group by 2-dimensional echocardiography. Increased 3DSTE-derived LV end-diastolic and end-systolic volumes could be seen in all athletes, the largest values were seen in the C. III. group. Global LV-LS (?18.5?3.0% vs. ?16.3?2.3%, p<0.05), LV-CS (?29.9?5.2% vs. ?28.1?4.8%, p<0.05) and LV-AS (?43.7?5.4% vs. ?40.9?4.8%, p<0.05) were increased as compared to those of non-athlete controls. All apical regional LV strains proved to be increased in all athletes with enhanced basal LS and midventricular LS, AS and 3DS. Global LV strains did not differ between the athlete groups based on static component of their training. No significant regional differences in LV strains could be detected between C. I., C. II. and C. III. groups (except in midventricular LV-LS). Conclusions Enhanced LV contractility represented by LV strains in longitudinal and circumferential directions could be demonstrated in elite athletes doing high dynamic sports, which does not depend on the grade of the static component of their training.
