Abstract

Background: Early repolarisation (ER) is commonly observed during cardiovascular screenings of young athletes and can present with various morphologies. However, its prevalence and clinical significance in male Brazilian soccer players have not been characterised. This study aimed to compare the prevalence of different ER patterns and assess their potential clinical significance in this population.

Methods: In this multicentre observational study, we analysed ECG data from male Brazilian soccer players who underwent preparticipation evaluations at 83 professional clubs across Brazil's five geographic regions between February 2002 and August 2024. Our analysis included white, mixed-race and black athletes, as well as seven distinct ER morphologies. Poisson regression with robust variance was used to derive age-adjusted prevalence ratios for the different ER morphologies.

Results: We included 6353 athletes (median (IQR) age: 19 (16-23) years; 2556 white, 2071 mixed-race and 1726 black individuals). ER patterns appeared in 2552 (40.2%) players. The most common ER morphologies with ST-segment elevation (STE) were a classic J-wave with ascending ST-segment (1275; 20.1%) and a discrete J-point with ascending ST-segment (735; 11.6%) in leads V4-V6. Without STE, the most frequent patterns were a slur on the downslope of the R-wave with ascending ST- segment (760; 12%), a slur with horizontal ST-segment (335; 5.3%) and a J-wave (199; 3.1%) in leads II, III and aVF. ER was more prevalent in black (48.1%) than in white (34.4%) or mixed-race (40.6%) athletes. Over a mean follow-up period of 4.4±3.1 years, no cases of sudden cardiac death were identified.

Conclusions: Our findings do not suggest that ER patterns observed in male Brazilian soccer players are associated with sudden cardiac death. Given the role of Brazil in exporting soccer talent, our results may help guide athlete assessments of ER worldwide.

巴西男性足球运动员明显的早期再极化模式：来自多中心研究的见解。

背景：早期复极化（ER）通常在年轻运动员的心血管筛查中观察到，并且可以表现为各种形态。然而，其在巴西男性足球运动员中的患病率和临床意义尚未被描述。本研究旨在比较不同ER模式的患病率，并评估其在该人群中的潜在临床意义。方法：在这项多中心观察性研究中，我们分析了2002年2月至2024年8月期间在巴西五个地理区域的83家职业俱乐部接受赛前评估的巴西男性足球运动员的心电图数据。我们的分析包括白人、混血和黑人运动员，以及七种不同的ER形态。采用稳健方差的泊松回归得出不同ER形态的年龄校正患病率。结果：我们纳入了6353名运动员(中位（IQR）年龄：19（16-23）岁；白人2556人，混血儿2071人，黑人1726人)。有2552名（40.2%）玩家出现ER模式。st段抬高（STE）最常见的内质网形态是典型的j波，st段上升(1275；20.1%)和st段上升的离散j点(735；11.6%)领先于V4-V6。在没有STE的情况下，最常见的模式是r波下坡上的模糊，ST段上升(760；12%)，具有水平st段的浆液(335；5.3%)和j波(199；3.1%)， II、III和aVF导联。ER在黑人运动员中（48.1%）比白人运动员（34.4%）或混血儿运动员（40.6%）更普遍。在平均4.4±3.1年的随访期间，未发现心源性猝死病例。结论：我们的研究结果并不表明在巴西男性足球运动员中观察到的内质网模式与心源性猝死有关。鉴于巴西在输出足球人才方面的作用，我们的研究结果可能有助于指导全球运动员对ER的评估。
