背景:众多研究均分别证明了耐力运动后存在心功能异常以及心脏损伤的生化证据,但两者之间尚缺乏公认的联系。本研究旨在确定耐力运动业余参与者中可见的短暂性心功能异常与心脏损伤生化证据之间的相关性,并得出这些损伤和功能异常的危险因素。方法和结果:在2004年和2005年波士顿马拉松赛前后,筛选出 Background: Numerous studies have demonstrated biochemical evidence of cardiac dysfunction and heart damage after endurance exercise, respectively, but there is a lack of accepted association between the two. The aim of this study was to determine the correlation between transient cardiac dysfunction and biochemical evidence of cardiac injury that can be seen in the amateur participants of endurance exercise and to derive the risk factors for these impairments and dysfunctions. Methods and Results: Screening out before and after the Boston Marathon in 2004 and 2005
