Sudden cardiac death is the most common cause of non-traumatic death in collegiate athletes. Marfan syndrome poses a risk for sudden cardiac death secondary to aortic root dilation leading to aortic dissection or rupture. Arm span to height ratio (ASHR) > 1.05 has been proposed as a screening tool for Marfan syndrome in pre-participation examinations (PPE) for collegiate athletes but limited data exists on the association between ASHR and aortic root diameter (ARD). This study examines the relationship between ASHR and ARD and assesses for predictors of ARD.
Retrospective chart review.
National Collegiate Athletic Association Division I University.
793 athletes across thirteen sports between 2012 and 2022 evaluated with PPE and screening echocardiogram.
Not applicable.
(1) Relationships between ASHR, SBP, BSA, and ARD amongst all athletes as well as stratified by ASHR >1.05 or ≤1.05 using univariate analysis. (2) Predictors of ARD using multivariate analysis using linear regression.
143 athletes (18 %) had ASHRs > 1.05. Athletes with ASHR > 1.05 had higher ARD (2.99 cm) than athletes with ASHR ≤ 1.05 (2.85 cm). Weak correlations were noted between ASHR, ARD, and SBP. Multivariate analysis showed that BSA, male sex, and participation in swimming were predictors of ARD. ASHR was not predictive of ARD in regression analysis.
These findings showed a tendency towards higher ARD in athletes with ASHR >1.05 but this observation was not statistically significant in multivariate analysis.
心源性猝死是大学生运动员非创伤性死亡的最常见原因。马凡综合征会因主动脉根部扩张导致主动脉夹层或破裂，从而引发心源性猝死风险。臂展与身高比（ASHR）>1.05已被提议作为大学生运动员赛前检查（PPE）中马凡综合征的筛查工具，但关于ASHR与主动脉根部直径（ARD）之间关联的数据有限。本研究探讨ASHR与ARD之间的关系，并评估ARD的预测因素。

2012年至2022年间，对13个运动项目的793名运动员进行了PPE评估和超声心动图筛查。
不适用。
（1）使用单变量分析，评估所有运动员以及按ASHR>1.05或≤1.05分层的运动员中，ASHR、收缩压（SBP）、体表面积（BSA）和ARD之间的关系。（2）使用线性回归多变量分析ARD的预测因素。
143名运动员（18%）的ASHR>1.05。ASHR>1.05的运动员的ARD（2.99厘米）高于ASHR≤1.05的运动员（2.85厘米）。ASHR、ARD和SBP之间存在弱相关性。多变量分析显示，BSA、男性性别和游泳项目参与情况是ARD的预测因素。在回归分析中，ASHR不能预测ARD。
这些发现表明，ASHR>1.05的运动员的ARD有升高趋势，但在多变量分析中，这一观察结果无统计学意义。
