Abstract

Background

Intensive training efforts are associated with hemodynamic changes accompanied by increases in cardiac output and stroke volume related to higher peak oxygen consumption and better athletic performance during exercise. These hemodynamic changes induce an enlargement of cardiac chambers, but also of the atria and may result in an athletes’ heart (AH). Data from large studies about atrial enlargement in AH are sparse.

Methods

Competitive athletes aged ≥18 years, who presented for pre-participation screening 04/2020–10/2021 were included in this study and stratified for AH (defined as physiologically increased heart volume >13.0 in males and >12.0 mL/kg in females).

Results

Overall, 646 athletes aged ≥18 years (median age 24.0 [20.0/31.0] years; 206 [31.9%] females) were included in our study 04/2020–10/2021; among these, 118 (18.3%) had an AH. The computed absolute heart volume was 969.4 (853.1/1083.0) mL in athletes with AH and 841.3 (707.4/966.3) mL in those without AH (p < 0.001). AH was associated with larger left ventricular mass (206.6 ± 39.0 vs. 182.7 ± 44.2 g, p < 0.001). LA area (15.4 [13.7/18.2] vs. 14.3 [12.0/16.3] cm², p < 0.001) and RA area (15.8 [13.8/18.6] vs. 14.5 [12.3/17.0] cm², p < 0.001) were enlarged in AH versus those athletes without AH. The logistic regressions confirmed an independent association of AH on LV mass (OR 1.05 [95% CI 1.04–1.06], p < 0.001). LA area (OR 1.29 [95% CI 1.19–1.39], p < 0.001) as well as RA area (OR 1.28 [95% CI 1.19–1.38], p < 0.001) were afflicted by AH.

Conclusion

An AH is accompanied by significant enlargement of the atria as well as increased cardiac muscle mass.

运动员心脏的心房适应性。

背景：高强度训练与血液动力学变化有关，伴随着心输出量和每搏容积的增加，运动时的峰值耗氧量更高，运动表现更好。这些血流动力学变化不仅会导致心腔增大，还会导致心房增大，并可能导致运动员心脏（AH）。有关 AH 中心房扩大的大型研究数据还很少：研究纳入了 2020 年 4 月至 2021 年 10 月参加赛前筛查的年龄≥18 岁的竞技运动员，并对其进行了 AH 分层（定义为男性心脏生理性增大 >13.0 mL/kg，女性 >12.0 mL/kg）：2020年4月至2021年10月，共有646名年龄≥18岁的运动员（中位年龄为24.0[20.0/31.0]岁；女性206人[31.9%]）参与研究，其中118人（18.3%）患有AH。计算得出的绝对心脏容积为：有 AH 的运动员为 969.4（853.1/1083.0）毫升，无 AH 的运动员为 841.3（707.4/966.3）毫升（P 2、P 2、P 结论）：AH 会导致心房明显增大，心肌质量增加。
