脑部体积和认知:一项随机临床试验
在PubMed上查看摘要
概括
此摘要是机器生成的。对于中风幸存者来说,心肺呼吸运动 (CRX) 是安全的,但没有保持海马体积. 然而,CRX可能对缺血性中风后的认知功能有好处,这表明未来的干预措施的潜力.
科学领域
- 神经科学
- 心血管健康
- 临床试验
背景情况
- 脑卒中患者面临认知障碍和痴呆症的风险增加.
- 目前没有经过验证的治疗方法可以预防中风后的认知衰退.
- 众所周知,心肺运动有助于保持大脑健康.
研究的目的
- 调查CRX干预是否可以在缺血性中风后保持海马体积 (HV) 和认知功能.
- 在中风幸存者中评估CRX计划的有效性和安全性.
主要方法
- 进行了2b期随机临床试验 (PISCES- ZODIAC).
- 参与者被随机分配到CRX (有氧和抵抗训练) 或对照组 (平衡和伸展).
- 主要结局是HV的相对变化;次要结局是12个月执行功能 (TMT- B).
主要成果
- CRX是安全的,耐受良好,没有严重的不良事件.
- 在CRX和对照组之间没有观察到海马体积的显著差异.
- 与对照组相比,CRX组在12个月后表现出执行功能的显著改善 (TMT-B).
结论
- 虽然CRX没有比对照干预更好地保持海马体积,但它对认知功能有潜在的益处.
- 在患有缺血性中风后,CRX可能是可行的认知维护策略.
- 需要进一步的研究来优化中风恢复的CRX协议.

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...
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 (CO) is an integral aspect of human physiology, reflecting the heart's efficiency and responsiveness to the body's needs. It represents the volume of blood that the left or right ventricle ejects into the aorta or pulmonary trunk each minute. The CO is calculated by multiplying the heart rate (HR)—the number of heartbeats per minute—by the stroke volume (SV)—the amount of blood pumped out with each heartbeat.
In an average resting adult male, the typical cardiac...
Regular physical activity is essential for maintaining cardiovascular health, with aerobic exercises being particularly effective. According to the American Heart Association, 150 minutes of moderate to intense aerobic exercise per week is recommended for a healthy heart. Aerobic activities may include brisk walking, running, bicycling, cross-country skiing, and swimming, ideally performed three to five times per week.
Sustained exercise increases the muscles' oxygen demand, which can be...
Exercise significantly impacts cardiovascular response, which is crucial for understanding patient health and designing effective treatment plans.
Light to moderate physical activity initiates a series of interconnected responses in the body. The heart rate modestly increases in anticipation of the workout, followed by widespread vasodilation as oxygen consumption by skeletal muscles increases. This results in decreased peripheral resistance, increased capillary blood flow, and accelerated...
