概括

大学学生的强度运动可以增加左心室体积并减少心肌张力. 患有症状的学生表现出更低的应变,尽管仍在正常范围内,这突显了早期心脏异常检测的必要性.

科学领域:

心脏病学心脏病学
运动医学运动医学
医疗成像医学成像

背景情况:

早期发现运动引起的心脏异常对于管理运动员至关重要.
参与密集运动的大学生可能会经历心血管适应.

研究的目的:

为了研究在接受密集炼的大学生中心血管适应.
使用心脏磁共振成像 (CMR) 来评估心脏变化.

主要方法:

一项前性,单中心研究,涉及50名大学生进行密集的耐力训练和23名对照.
心脏磁共振成像 (CMR) 用于计算左心室体积,喷射率和全球峰值应变.
根据与运动相关的症状,参与者被分为症状和无症状组.

主要成果:

与对照人群相比,运动参与者表现出较高的末端透气左心室体积和减少的喷射分数和全球纵向应变.
与无症状参与者和对照人群相比,有症状的运动参与者表现出明显减少的峰值菌株.
在无症状病例和对照病例中观察到减少的周围透析峰值应变率.

结论:

在年轻的大学生中,高强度的运动会导致左心室体积增加和心肌压力减少.
症状病例中心肌菌株的减少,虽然在非病理的范围内,但需要注意潜在的早期发现心脏异常.

Magnetic Resonance Imaging

Magnetic Resonance Imaging

Magnetic resonance imaging (MRI) is a noninvasive medical imaging technique based on a phenomenon of nuclear physics discovered in the 1930s, in which matter exposed to magnetic fields and radio waves was found to emit radio signals. In 1970, a physician and researcher named Raymond Damadian noticed that malignant (cancerous) tissue gave off different signals than normal body tissue. He applied for a patent for the first MRI scanning device in clinical use by the early 1980s. The early MRI...
