Abstract

Cardiac sequelae following sport-related concussion are not well understood. This study describes changes in the cardiac cycle timing intervals and contractility parameters during the acute phase of concussion. Twelve athletes (21 ± 2 years, height = 182 ± 9 cm, mass = 86 ± 15 kg, BMI = 26 ± 3 kg/m²) were assessed within 5 days of sustaining a diagnosed concussion against their own pre-season baseline. A non-invasive cardiac sensor (LLA Recordis^TM) was used to record the cardiac cycle parameters of the heart for 1 minute during supine rest. Cardiac cycle timing intervals (Isovolumic relaxation and contraction time, Mitral valve open to E wave, Rapid ejection period, Atrial systole to mitral valve closure, Systole, and Diastole) and contractile forces (Twist force and Atrial systole: AS) were compared. Systolic time significantly decreased during acute concussion (p = 0.034). Magnitude of AS significantly increased during acute concussion (p = 0.013). These results imply that concussion can result in altered systolic function.

急性运动相关脑震荡后的心动周期计时和收缩力。

人们对运动相关脑震荡后的心脏后遗症还不甚了解。本研究描述了脑震荡急性期心动周期定时间隔和收缩力参数的变化。12 名运动员（21 ± 2 岁，身高 = 182 ± 9 厘米，体重 = 86 ± 15 千克，体重指数 = 26 ± 3 千克/平方米）在确诊脑震荡后 5 天内接受了评估，并与自己的赛季前基线进行了对比。使用无创心脏传感器（LLA RecordisTM）记录仰卧休息时 1 分钟的心脏周期参数。对心动周期的时间间隔（等容舒张和收缩时间、二尖瓣开放至 E 波、快速射血期、心房收缩至二尖瓣关闭、收缩期和舒张期）和收缩力（扭转力和心房收缩：AS）进行了比较。在急性脑震荡期间，收缩时间明显缩短（p = 0.034）。急性脑震荡时 AS 的幅度明显增加（p = 0.013）。这些结果表明，脑震荡可导致收缩功能改变。

期刊介绍： Accounts of Chemical Research presents short, concise and critical articles offering easy-to-read overviews of basic research and applications in all areas of chemistry and biochemistry. These short reviews focus on research from the author’s own laboratory and are designed to teach the reader about a research project. In addition, Accounts of Chemical Research publishes commentaries that give an informed opinion on a current research problem. Special Issues online are devoted to a single topic of unusual activity and significance. Accounts of Chemical Research replaces the traditional article abstract with an article "Conspectus." These entries synopsize the research affording the reader a closer look at the content and significance of an article. Through this provision of a more detailed description of the article contents, the Conspectus enhances the article's discoverability by search engines and the exposure for the research.
