概括
患有痴呆症的患者经历了更严重的中风,但接受的机械血栓切除术 (MT) 较少. 痴呆症没有独立增加MT后的死亡率,但它增加了内出血的风险.
科学领域:
- 神经学 神经学
- 老年病的医生 老年病的医生
- 公共卫生 公共卫生
背景情况:
- 痴呆症在急性缺血性中风 (AIS) 患者中普遍存在,尤其是老年人.
- 痴呆症患者经常出现更严重的中风缺陷.
研究的目的:
- 为了比较中风的严重程度,机械血栓切除术 (MT) 的利用,以及患有痴呆症和没有痴呆症的AIS患者的结果.
- 调查痴呆症对MT结果的独立影响,根据中风严重程度进行调整.
主要方法:
- 美国因AIS住院的回顾性分析 (2016年10月至2017年12月).
- 在患有和没有痴呆症的患者之间比较中风严重程度,MT使用和出院结果 (死亡率,功能性处置,内出血).
- 多变量逻辑回归以调整混因素,包括中风严重程度.
主要成果:
- 10.2%的AIS入院患者有先前存在的痴呆症,老年患者的患病率更高 (25%的80岁以上患者).
- 痴呆症患者的中位数呈现国家卫生研究院中风量表得分 (7对4) 的中位数较高,接受MT的几率较低 (OR,0.43).
- 虽然在MT后的痴呆症患者的住院死亡率较高 (21.3%对11.2%),但在调整中风严重程度后,这种差异并不显著. 痴呆症与MT后内出血风险增加有关 (OR, 1.57).
结论:
- 痴呆症在AIS中很常见,与中风严重程度的增加有关.
- 尽管中风更严重,但痴呆症患者接受MT的频率较低.
- 痴呆症不是MT后死亡的独立预测因素,但增加了内出血的风险.

Dementia is a collective term for cognitive disorders primarily affecting memory, thinking, and reasoning. It is not a specific disease but a syndrome, with Alzheimer's disease being the most common cause, accounting for approximately 60-80% of cases. Other types include vascular dementia, Lewy body dementia, and frontotemporal dementia. Dementia affects millions worldwide, particularly older adults, though it is not a normal part of aging.

01:27Regulation of Stroke Volume
5.1K
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...

30.7K
Chemical reactions often occur in a stepwise fashion, involving two or more distinct reactions taking place in a sequence. A balanced equation indicates the reacting species and the product species, but it reveals no details about how the reaction occurs at the molecular level. The reaction mechanism (or reaction path) provides details regarding the precise, step-by-step process by which a reaction occurs.
For instance, the decomposition of ozone appears to follow a mechanism with two steps:

01:17Ischemic Heart Disease: Overview
3.4K
Ischemic heart disease occurs when the heart's blood supply dwindles, causing an ominous lack of oxygen and nutrients. This deficiency, stemming from reduced or obstructed blood flow, spells danger, leading to heart muscle damage and dysfunction.
Atherosclerosis, the primary malefactor, orchestrates this dangerous condition. It manifests as the accumulation of fatty deposits, akin to insidious plaques, within arterial walls. As time elapses, these plaques metamorphose, hardening and...

01:58Mechanical Protein Functions
5.6K
Proteins perform many mechanical functions in a cell. These proteins can be classified into two general categories- proteins that generate mechanical forces and proteins that are subjected to mechanical forces. Proteins providing mechanical support to the structure of the cell, such as keratin, are subjected to mechanical force, whereas proteins involved in cell movement and transport of molecules across cell membranes, such as an ion pump, are examples of generating mechanical force.

01:11Cardiac Output and Stroke Volume
4.8K
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.
