摘要：Long-term sports training leads to myocardial adaptations, with remodelling of the heart chambers. However, while myocardial adaptations of the left heart are well described, remodelling of the right heart and its impact on the development of arrhythmias is still debated. To conduct a systematic review on right ventricle (RV) and right atrium (RA) structural and functional changes in athletes who participate in long-term endurance training. Systematic review. A systematic literature search was conducted. All the articles reporting right heart echocardiographic (ECHO) and cardiac magnetic resonance (CMR) parameters evaluated in endurance athletes and sedentary subjects were considered eligible. A multivariate analysis was conducted to investigate whether age, sex, body surface area (BSA), intensity of training are associated with RV ECHO, CMR parameters and RA ECHO parameters. A positive association between age and right atrium area (RAA) (
P = 0.01) was found. This is a negative association to RV E/A (
P = 0.004), and RV end diastolic diameter (RVED) longitudinal (
P = 0.01). A positive association between BSA and RVED middle (
P = 0.001), as well between BSA and RAA (
P = 0.05) was found, along with a negative association with RV E/A (
P = 0.002). A positive association between intensity of training and RV end systolic area (RVESA) (
P = 0.03), RV end diastolic volume indexed (RVEDVI) (
P = 0.01), RV end systolic volume indexed (RVESVI) (
P = 0.01) was found, along with a negative association with ejection fraction (EF %) (
P = 0.01). Endurance athletes demonstrated an association between RV remodelling and age, BSA and intensity of training.
