概括
在患有缺血性中风或TIA的患者中,左心房储压力低于20%可能表明血栓源并预测未来心房动. 这一发现有助于识别中风的起源,并指导患者的治疗.
科学领域:
- 心脏病学 心脏病学
- 神经学 神经学
- 医疗成像医学成像
背景情况:
- 鉴定缺血性中风 (IS) 和短暂缺血性发作 (TIA) 的心脏来源至关重要.
- 心房动 (AF) 是心血管栓塞性IS的常见原因之一.
- 使用2D Speckle-Tracking的左心房 (LA) 储应变 (RS) 分析优于LA维度,用于预测阳性AF和IS.
研究的目的:
- 调查LA储菌株 (RS) 与IS的栓塞性起源 (心血管栓塞与ESUS) 之间的关联.
- 确定与IS相关的因素.
- 探索RS和AF发生之间的关系,确定与RS受损 (<20%) 相关的因素.
主要方法:

- 使用2D Speckle-Tracking来测量储应变 (RS) 的LA功能的分析.
- 在随访期间,RS值与中风病因和AF发生的相关性.
主要成果:
- 在RS<20%和IS (不包括PFO) 的栓塞性起源之间发现了显著的关联,P=0.01.
- 在随访期间,RS<20%与随后发生的心房有关 (P=0.04).
- 中位数RS为27%,其中86%的患者表现出RS<39%.
结论:
- 在IS/TIA急性阶段减少LA储菌株 (<20%) 可能表明栓塞性中风病因.
- 这一发现可以帮助预测在没有先前AF史的患者的随访期间心房的发生.
- 在评估栓塞性中风风险和AF发展方面,LA储菌株是一种有价值的参数.

Regulation of Stroke Volume
4.7K
The regulation of stroke volume, which is the amount of blood the heart pumps out during each heartbeat, is critical for maintaining a healthy circulatory system. Stroke volume is influenced by three main factors: preload, contractility, and afterload.
Preload refers to the degree of stretch on the heart before it contracts. It's analogous to the stretching of a rubber band; the more it's stretched, the more forcefully it snaps back. This concept is encapsulated in the Frank-Starling law of the...

Cardiac Output II: Effect of Stroke Volume on Cardiac Output
3.1K
Cardiac output (CO), the amount of blood the heart pumps per minute, is a parameter in cardiovascular physiology determined by stroke volume and heart rate. Stroke volume, the amount of blood pushed from one of the ventricles per heartbeat, is influenced by preload, afterload, and contractility.
Preload
Preload refers to the initial elongation of the cardiac myocytes before contraction and is related to the volume of blood filling the heart at the end of diastole, or end-diastolic volume. The...

Imbalances in Cardiac Output
2.3K
The heart's primary function is to pump blood throughout the body, maintaining a balance between blood sent out (cardiac output) and blood returning (venous return). If this balance is disrupted, it can result in congestive heart failure (CHF), a severe condition where the heart becomes an inefficient pump, leading to inadequate blood circulation.
CHF can occur due to the failure of either side of the heart. Left-side failure leads to pulmonary congestion—the right side continues to send...
