概括
身体活跃的女性在月经周期的状阶段显示出略高的左心室质量指数 (LVMi). 这种心脏结构的变化没有影响左心室功能或心电图读数.
科学领域:
- 心脏病学 心脏病学
- 生殖内分泌学 生殖内分泌学
- 运动生理学 体育生理学
背景情况:
- 月经周期阶段对活跃女性心脏结构和功能的影响仍未得到充分研究.
- 之前的研究还没有使用3D心声回声和心电图来评估这些与月经周期有关的心脏变化.
研究的目的:
- 调查月经阶段 (卵泡,排卵,白色细胞) 对左心室 (LV) 结构和功能的影响.
- 评估心脏参数使用3D心声回声和休息心电图在健康,身体活跃的女性.
主要方法:
- 16名身体活跃的女性 (20±2岁) 在三个月经周期点进行了3D心声学和心电图.
- 评估的LV终端透气体体积指数 (LVEDVi),LV喷射分数 (LVEF),全度指数的LV质量 (LVMi),扭力和应变 (GLS,GCS,GRS).
- 分析了P-QRS波的心电图,轴偏差,腔室扩大和心律失常.
主要成果:
- 在质期 (36.4 g/m^2.7) 与卵泡 (35.0 g/m^2.7) 和排卵 (34.7 g/m^2.7) 阶段 (p=0.026) 相比,观察到 LV 质量指数 (LVMi) 的统计学上显著增加.
- 在月经周期各阶段的其他LV结构或功能参数中没有发现显著差异.
- 在整个月经周期中,没有检测到心电图变量的显著变化或心律失常的证据.
结论:
- 在身体活跃的雌性体内,在黄体阶段发生LVMi的轻微但显著升高.
- 这种与黄质相相关的LVMi增加不会影响左心室的整体功能或心电图参数.
- 这些发现强调了在研究和临床环境中的连续心脏评估中考虑月经周期阶段的重要性.

Imaging Studies for Cardiovascular System I:Echocardiography
371
Cardiac imaging studies encompass a wide range of noninvasive and minimally invasive techniques designed to visualize the heart's structure and function in detail. One such technique is echocardiography, which uses high-frequency ultrasound waves to produce detailed images of the heart, known as echocardiograms.
Indications: Echocardiography is utilized to diagnose heart failure, valve disorders, and myocardial infarction. It also assesses cardiac structures' size, shape, and motion,...

Echocardiography plays a role in assessing cardiac health and detecting heart conditions, with various types providing critical insights for diagnosis and treatment.
Types of Echocardiography
Transthoracic Echocardiography (TTE)
TTE is the most common type of echocardiogram which involves placing a transducer on the patient's chest, emitting sound waves to create heart images. TTE is invaluable for evaluating the heart's size, structure, and motion, making it particularly useful for...
