Abstract
<p><strong>Background:</strong> Structural and functional adaptations in the athlete's heart can mimic cardiomyopathies, necessitating precise cardiac assessment. Both right ventricular (RV) function and left atrial (LA) strain are critical components of this evaluation. Traditional parameters, such as TAPSE for RV function and volumetric assessments for LA size, may fail to capture subtle cardiac remodeling. Advanced techniques like RV free wall strain (RVFWS) and LA strain provide deeper insights into myocardial mechanics and physiological adaptations in athletes.</p> <p><strong>Aims:</strong> This study aimed to comprehensively evaluate RV and LA remodeling and function in professional soccer players compared to healthy controls, assessing the utility of strain imaging in distinguishing physiological adaptations from potential dysfunction.</p> <p><strong>Methods:</strong> A retrospective analysis was conducted on echocardiographic data, including RV free wall strain (RVFWS) and LA strain, from professional male soccer players and healthy male controls. Imaging was performed using the GE Vivid E95 ultrasound system, with data analyzed via EchoPAC V.206 software (GE Vingmed Ultrasound AS, Horten, Norway). Statistical analyses were conducted using SPSS v.27.</p> <p><strong>Results:</strong> The study included 111 professional male athletes (median age: 24 [21–31] years) and 71 healthy male controls (median age: 26 ± 4 years). Right ventricular free wall strain (RVFWS) did not significantly differ between groups (p = 0.898), measuring -23.4 ± 3.6% in athletes and -23.8 (-25.9 - -21.7%) in controls. However, both pulmonary acceleration time and indexed right atrium volume were significantly higher in athletes (p <0.001). Athletes had a significantly higher indexed left atrial end-systolic volume compared to the control group (41 ± 9 ml/m² vs. 31 ± 7 ml/m², p<0.001). Despite the difference in volume, the early and late diastolic tissue velocities were similar in both groups and E/E’ was lower (4.4 ± 0.9 vs. 5.0 (4.5-5.8), p<0.001). There were no significant differences between athletes and the control group in Left Atrial Reservoir Strain (LASr) and Left Atrial Conduit Strain (LAScd). The active contraction of the left atrium during atrial systole is reduced in athletes, which had a significantly lower left atrial contraction strain compared to the control group (-9 (-11 – -8)% vs. -12 ± 4%, p<0.001).</p> <p><strong>Conclusion:</strong> In professional athletes, RV free wall strain (RVFWS) was comparable to controls, indicating preserved RV function despite remodeling, such as increased pulmonary acceleration time and right atrial volume. LA remodeling showed increased size and reduced contraction strain, while reservoir and conduit strain remained normal. These findings suggest that observed changes reflect physiological adaptations to the high cardiac output demands of chronic exercise. Strain imaging offers valuable insights into the cardiac remodeling of athletes' hearts.</p>
