まとめ
システム性白血球症 (SLE) の患者は,特に若い成人の場合,心血管リスクのマーカーである動脈硬化症 (ArS) の増加を示します. これはArSを強調しています.
科学分野:
- 心血管医学
- リウマトロジ
- 血管生物学
背景:
- システミック・ルプス・エリーテマトサス (SLE) は,心血管疾患の罹患率と死亡率を著しく上昇させる.
- 動脈硬化 (ArS) は一般人群における心血管リスクマーカーとして認識されているが,SLEにおけるその役割は不明である.
研究 の 目的:
- 健康な対照群と比較して,SLE患者におけるARSの流行を調査する.
- SLEにおけるArSの予測要因を特定する.
- SLE患者におけるARSと亜臨床性動脈硬化症の関連性を調査する.
主な方法:
- 動脈の硬さは,動脈動脈波速度 (cfPWV) と増幅指数 (AIx@ 75) を用いて194人のSLE患者および194人のHCで評価された.
- サブクリニック性動脈硬化症は,頸動脈/股関節超音波検査で評価された.
- 線形回帰モデルでは,従来のSLE特異的心血管リスク因子 (CVRF) を含むArSの予測因子を特定しました.
主要な成果:
- SLE患者では,HC患者と比較してAIx@75が上昇し,cfPWVでは有意な差異はなかった.
- 若いSLE患者 (18~37歳) は,HC患者と比較して,cfPWVとAIx@75の増加を示した.
- cfPWVとAIx@75は,アテロスクレロスのプラークと独立して関連しており,SLE患者における年齢,平均動脈圧,および可変のCVRFの影響を受けていた.
結論:
- SLE患者におけるArSの上昇は,亜臨床性動脈硬化症と関連しており,心臓血管リスク評価におけるその重要性を強調しています.
- 動脈の硬さは,低から中程度の心血管リスクを含む,若年から中年のSLE患者における心血管リスクの階層化に特に関連しています.

01:27Atherosclerosis II: Clinical Manifestations and Diagnostic Tests
38
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)...

34
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...

01:27Assessment of the Cardiovascular System III: Palpation
492
Palpation involves feeling the body to evaluate texture, size, consistency, and tenderness for assessing cardiovascular health. The following steps are organized in a head-to-toe order:
Jugular Venous Pressure (JVP) Measurement
Position the patient at a thirty- to forty-five-degree angle or in a semi-fowler's position. Look for the highest point of pulsation in the internal jugular vein and measure the vertical distance to the angle of Loius or sternal angle. A normal JVP is 3-4 cm above...

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...

Nursing management for a patient with arteriosclerosis involves a comprehensive approach focusing on lifestyle modification, disease monitoring, education, and symptomatic care. Here is an overview of effective nursing strategies:Assessment and Monitoring: Initial and ongoing assessments are crucial. Nurses must document the patient's medical history, including any hypertension, diabetes, hyperlipidemia, and other cardiovascular diseases. Assessments also cover family history and lifestyle...

01:11Overview of Systemic Arteries
1.0K
The human body is a complex, well-organized machine, and at the heart of its operations lies the circulatory system. This network of blood vessels, which includes systemic arteries, plays a vital role in maintaining life by transporting nutrients, oxygen, and waste products to and from cells throughout the body.
Systemic circulation is the part of the cardiovascular system that carries oxygenated blood away from the heart to the body's tissues and returns deoxygenated blood back to the...
