まとめ
認知症患者はより重度の脳卒中を経験したが、機械的血栓回収療法(MT)の施行率は低かった。認知症はMT後の死亡率を独立して増加させなかったが、頭蓋内出血のリスクを高めた。
科学分野:
- 神経学;老年医学;公衆衛生
背景:
- 認知症は急性虚血性脳卒中(AIS)患者、特に高齢者に蔓延している。;認知症患者は、より重度の脳卒中後遺症を呈することが多い。
研究 の 目的:
- AIS患者における認知症の有無による脳卒中重症度、機械的血栓回収療法(MT)の利用、および転帰の比較。;脳卒中重症度を調整して、MT転帰に対する認知症の独立した影響を調査する。
主な方法:
- 米国におけるAIS(2016年10月~2017年12月)の入院のレトロスペクティブ分析。;認知症の有無による脳卒中重症度、MT使用、および退院転帰(死亡率、機能的転帰、頭蓋内出血)の比較。;脳卒中重症度を含む交絡因子を調整するための多変量ロジスティック回帰。
主要な成果:
- 急性虚血性脳卒中(AIS)入院患者の10.2%に既存の認知症があり、高齢者(80歳以上で25%)で有病率が高かった。;認知症患者は、入院時のNIHSSスコア(中央値7対4)が高く、MTを受けるオッズが低かった(OR、0.43)。;MT後の院内死亡率は認知症患者で高かった(21.3%対11.2%)が、脳卒中重症度で調整後、この差は有意ではなかった。認知症はMT後の頭蓋内出血リスクの増加と関連していた(OR、1.57)。
結論:
- 認知症はAISで一般的であり、脳卒中重症度の増加と関連している。;より重度の脳卒中にもかかわらず、認知症患者はMTを受ける頻度が低かった。;認知症はMT後の死亡率の独立した予測因子ではないが、頭蓋内出血のリスクを高める。

Dementia
562
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.

Regulation 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...

Reaction Mechanisms
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:

Ischemic 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...

Mechanical 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.

Cardiac 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.
