- 放射線科
背景:
- 高血圧 (BP) とその変動性は,アルツハイマー病 (AD) と関連しています.
- ADに関連する脳の領域におけるBPと皮質の厚さの関連は不明である.
- この文脈における24時間BPモニタリングの役割は広く研究されていません.
研究 の 目的:
- 診察室や24時間の診察室での血圧測定と,ADに関連した脳領域の皮質の厚さとの関係を調べる.
- 認知症のない人の脳構造に対する 血圧のレベルと変化の影響を調べる
主な方法:
- 認知症のない304人の被験者の横断分析
- 診察室と24時間の診察室での血圧データです
- MRIを用いて,ADに関連する10つの脳領域の皮質の厚さを評価した.
- 調整された線形回帰モデルを用いて関連をテストした.
主要な成果:
- 静脈圧の上昇は 側頭葉皮質と 後頭葉皮質の薄れ方と相関する
- 24時間および夜間の高血圧は,皮質の薄い領域と関連していました.
- 前頭,側頭,後頭帯状皮質の薄くなり,24時間の血圧の変動が増加した.

01:18Neural Regulation of Blood Pressure
3.4K
The neural regulation of blood pressure involves intricate interactions between the autonomic nervous system (ANS) and cardiovascular system, ensuring adequate perfusion of tissues. This regulation primarily occurs through baroreceptor and chemoreceptor reflexes, involving both short-term and long-term mechanisms.
Baroreceptor Reflex
Baroreceptors, located in the carotid sinuses and aortic arch, detect changes in blood pressure. When blood pressure rises, these stretch-sensitive receptors...

Assessing blood pressure is a standard procedure executed in virtually all medical environments. The method utilized today was established over a hundred years ago by an innovative Russian doctor, Dr. Nikolai Korotkoff. The soft ticking noise, known as Korotkoff sounds, heard while taking blood pressure readings results from turbulent blood flow within the vessels. The apparatus required for this procedure includes a sphygmomanometer, a blood pressure cuff attached to a gauge, and a...

When assessing blood pressure (BP), healthcare professionals must consider various factors and potential unexpected outcomes to ensure accurate readings and provide proper patient care. Adhering to these guidelines is essential to achieving the most reliable results.
Monitoring Both Arms:
Monitoring BP in both arms during the initial assessment is advisable, as the systolic value may differ by five to ten mm Hg between arms. For subsequent BP assessments, use the arm with the higher reading.
