Cardiac magnetic resonance (CMR) has a growing role in evaluating athletes' hearts. Mapping techniques provide added value for tissue characterization, but data on athletes and sports disciplines are lacking. To describe native mapping values in a cohort of Olympic athletes and evaluate the influence of sports discipline and sex.
A group of 300 Olympic athletes (13% skill, 20% power, 25% mixed, 42% endurance, 58% male) with unremarkable cardiovascular screening and a control group of 42 sedentary subjects (52% male) underwent CMR without contrast administration. Athletes were divided based on sex and sports categories according to the ESC classification. Among athletes of different sports categories and controls, endurance presented the lowest value of T1 mapping (P < 0.001). No differences in T2 mapping were observed (P = 0.472). Female athletes had higher values of T1 native myocardial mapping compared with males (P = 0.001), while there were no differences in T2 mapping (P = 0.817). Male athletes with higher left ventricular mass indexed (LV-Massi) had lower values of T1 mapping (P = 0.006) and slightly higher values of T2 mapping, even if not significant (P = 0.150). Female athletes with higher LV-Massi did not show significant differences in T1 and T2 mapping (P = 0.053 and P = 0.438).
T1 native myocardial mapping showed significant differences related to sports disciplines and gender. Athletes with the largest LV remodelling, mostly endurance and mixed, showed the lowest values of T1 mapping. Male athletes showed lower values of T1 mapping than females. No significant differences were observed in T2 mapping related to sports disciplines and gender.
心脏磁共振成像（CMR）在评估运动员心脏方面的作用日益重要。成像技术为组织特征描述提供了附加价值，但缺乏关于运动员和运动项目的数据。本研究旨在描述一组奥运运动员的原始成像值，并评估运动项目和性别的影响。
300名奥运运动员（技巧类占13%，力量类占20%，混合类占25%，耐力类占42%，男性占58%），其心血管筛查结果正常，以及42名久坐不动的对照者（男性占52%）接受了无对比剂的CMR检查。运动员根据欧洲心脏病学会（ESC）分类按性别和运动类别进行分组。在不同运动类别的运动员和对照组中，耐力类运动员的T1成像值最低（P<0.001）。T2成像未观察到差异（P = 0.472）。与男性相比，女性运动员的T1心肌原始成像值更高（P = 0.001），而T2成像无差异（P = 0.817）。左心室质量指数（LV-Massi）较高 的男性运动员T1成像值较低（P = 0.006），T2成像值略高，尽管不显著（P = 0.150）。LV-Massi较高的女性运动员在T1和T2成像上未显示出显著差异（P = 0.053和P = 0.438）。
T1心肌原始成像显示出与运动项目和性别相关的显著差异。左心室重塑最明显的运动员，主要是耐力类和混合类，T1成像值最低。男性运动员的T1成像值低于女性。在与运动项目和性别相关的T2成像中未观察到显著差异。
