【 摘 要 】

Cardiac hypertrophy has been continuing as the subject of the ‘hottest’ topic in research field for a long time since it creates pathophysiologic and clinical issues by structural and functional alterations of heart. Probably, it is explained by the prevalence of cardiovascular disorders in all-cause mortality. It seems that, on the basis of a contemporary data, the perception of ‘benign’ nature of the cardiac hypertrophy in athletic population is blurred. The improvement of imaging modalities and assessment tools largely contributed to comprehensive integration of scientific and clinical standpoints of athletic hypertrophy. Conventionally pathologic hypertrophy believed to be developed in a case of cardiovascular diseases, while the athlete’s heart resulted by long-standing physical training. According to recent evidence, a gray zone of hypertrophy became emerged between physiological and pathological entities, which require further extensive investigations. The emerging huge challenges in sports cardiology are overtraining and doping abuse of elite athletes by the development of an excessive cardiac hypertrophy with the increased risk of cardiovascular adverse outcomes. Additionally, the higher prevalence of sudden cardiac death in sportsmen compared to sedentary matches, especially in case of athletes with known or suspected cardiovascular diseases necessitated scrupulous investigation of athletic heart syndrome. The development, variety and severity of cardiac hypertrophy fluctuate by sportive branch and training mode. The significance of problem is more emphasized when cohort studies represented survival differences by means of cardiovascular parameters between athletes and sedentary subjects and cardiac patients.In this review, we aimed to represent recent physiological and clinical standpoints regarding to athletic heart syndrome as well as its difference from sedentary heart changes and pathological hypertrophy, its association with sudden cardiac death.
