Physiological Versus Pathological Cardiac Adaptations in Athletes: Unravelling the Complexities of the Athlete’s Heart through Advanced Echocardiographic Imaging

Introduction: The "athlete’s heart" refers to cardiac adaptations from intense training, which can mimic conditions like hypertrophic cardiomyopathy (HCM) and arrhythmogenic right ventricular cardiomyopathy (ARVC). This study aims to differentiate physiological and pathological cardiac hypertrophy in athletes using advanced echocardiographic techniques. Methodology: A literature review of studies from 2000–2024 was conducted using PubMed, Scopus, and Google Scholar, focusing on cardiac remodeling, echocardiographic evaluation, and sudden cardiac death (SCD) risk in athletes. Discussion: Endurance athletes develop eccentric hypertrophy, while strength athletes exhibit concentric hypertrophy. Physiological adaptations maintain normal function, whereas HCM and ARVC present with structural abnormalities and increased SCD risk. Advanced imaging, including strain and tissue Doppler, is crucial for accurate diagnosis. Conclusion: Echocardiographic screening is essential for distinguishing normal adaptations from dangerous pathologies in athletes. This study highlights the role of advanced imaging in preventing misdiagnosis and ensuring cardiovascular safety in sports.
