まとめ
周辺動脈硬化 (faPWV) は,心血管疾患 (CVD) との境界線逆関連を示し,中央動脈硬化 (cfPWV) は,正に関連した. cfPWVとfaPWVの比率 (cf-fa比率) は,CVDのリスクをより良く予測した.
科学分野:
- 心血管医学
- 生物医学工学
- 流行病学
背景:
- 動脈動脈波速度 (cfPWV) は中央動脈の硬さを測定し,心血管疾患 (CVD) を予測する.
- 股関節脈波速度 (faPWV) は外周動脈の硬さを測定しますが,そのCVD関連性はあまり理解されていません.
研究 の 目的:
- faPWVとcfPWVとCVDの関連性を調査する.
- cfPWV,faPWV,およびその比率 (cf-fa比率) をCVDリスクと比較する.
主な方法:
- 過去のCVDのない3,402人のARIC参加者の分析.
- Omron VP-1000 Plusを使用してfaPWVとcfPWVを測定する.
- 多変量コックス比例リスクモデルが,心血管疾患 (CHD,HF,脳卒中) のアウトカムを平均9. 0年の追跡期間で評価するために使用された.
主要な成果:
- faPWVは,CVDとの境界線逆相関を示した (全調整後,p- for- trend=0. 096).
- cfPWVは心血管疾患と正の関連性を示した (上下四分の一のHRは1. 22で,p- for- trend=0. 043).
- cf- fa比は,特に心不全において,cfPWV (HR1. 37, p- for- trend=0. 005) よりもCVDとの強い関連性を示した.
結論:
- 中枢と周辺の動脈の硬さは,CVDに対する明確な予後的な影響を及ぼします.
- cf- fa比は,心血管リスク評価の貴重なツールとして役立つ.
- 発見は,CVDリスクの階層化のための代替手段として,cf-fa比を支持する.

Atherosclerosis is a progressive disorder that leads to the thickening and narrowing of arterial walls due to plaque buildup. This condition can cause various symptoms depending on the arteries affected:Coronary Artery Disease (CAD): This condition affects the coronary arteries and may lead to chest pain (angina), shortness of breath (dyspnea), heart attacks, and other heart disease symptoms.Cerebrovascular Disease: This affects blood flow to the brain, causing transient ischemic attacks (TIAs)...

Clinical manifestationsPeripheral Arterial Disease (PAD) manifests through a range of symptoms, from the characteristic intermittent claudication to atypical presentations and severe complications in advanced stages. Intermittent claudication, a hallmark symptom of PAD, presents as exercise-induced muscle pain that typically resolves within minutes of rest. This pain is reproducible and stems from inadequate blood flow, leading to the accumulation of lactic acid produced during anaerobic...

01:30Peripheral Artery Disease I: Introduction
32
Peripheral artery disease (PAD) predominantly results from atherosclerosis, which involves the accumulation of fatty deposits, or plaques, within the walls of arteries. This causes them to narrow and harden, significantly reducing blood flow. PAD predominantly affects the legs, particularly the arteries supplying the thighs and calves. In rare cases, it may involve other arteries, including those in the arms.Etiology of PAD:The principal cause of PAD is atherosclerosis, which results from fatty...

Management of atherosclerosis involves an integrated strategy encompassing pharmacological treatment, surgical interventions, lifestyle changes, and nutrition therapy to address the multifactorial nature of the disease.Pharmacological TherapyA cornerstone of atherosclerosis management is the use of pharmacological agents. Statins, such as atorvastatin, are pivotal in inhibiting HMG-CoA reductase, an enzyme that catalyzes an initial step in cholesterol synthesis in the liver. This reduction in...

Atherosclerosis is a progressive disorder characterized by the buildup of plaques on the arterial inner wall, causing them to narrow and harden over time. These plaques comprise lipids, calcium, blood components, carbohydrates, and fibrous tissue. The process primarily affects the intima of large and medium-sized arteries, reducing blood flow in any artery.Etiology and risk factorsThe cause of atherosclerosis is multifactorial, involving a complex interplay among endothelial injury, lipid...

Coronary Artery Disease (CAD): An Overview with Scientific InsightsCoronary Artery Disease (CAD), often referred to as C-A-D, is a prevalent blood vessel disorder classified under the broader category of atherosclerosis. Atherosclerosis is a pathological process characterized by the hardening and narrowing of arteries due to the accumulation of atherosclerotic plaques. These plaques are composed of cholesterol, fatty substances, inflammatory cells, calcium, and fibrin, reducing blood flow to...
