概括
大脑白质的高强度与冠状动脉疾病和大脑动脉狭窄相关. 对老年患者,特别是患有恶性黑色素瘤的老年患者来说,早期发现这些疾病至关重要.
科学领域:
- 心血管成像和神经学.
- 瘤学和诊断成像学.
背景情况:
- 大脑白质高强度 (WMH) 和冠状动脉疾病 (CAD) 在老年人中很常见.
- WMH通常与小血管疾病有关,而CAD主要是由动脉样硬化引起的.
- 需要进一步调查WMH和CAD之间的关系.
研究的目的:
- 在新诊断的恶性黑色素瘤患者中调查WMH和CAD之间的相关性.
- 评估临床因素对WMH的预测价值.
主要方法:
- 120名黑色素瘤患者CT扫描和脑MRI的回顾性分析 (2015年1月1日2023年6月30日).
- 冠状动脉疾病通过视觉CT扫描分析评估;白质变化使用MRI上的Fazekas分数进行评估.
- 从患者记录中提取了临床数据,包括年龄,糖尿病和高血压.
主要成果:
- 在CAD和年龄 (r=0.48) 和Fazekas分数 (周周腔室r=0.46,皮层下r=0.55) 之间发现了显著的相关性.
- 一个线性模型表明,年龄,CAD,糖尿病和高血压预测WMH.
- 将动脉样硬化和动脉狭窄症添加到模型中显示,动脉样硬化的重要性略有下降,并揭露了与动脉狭窄症的潜在虚假相关性.
结论:
- 白质过强度,动脉狭窄和冠状动脉疾病之间存在显著的相关性.
- 临床相关性:在WMH和CAD患者中,应排除心血管狭窄.

Calcium-Scoring CT ScanA calcium-scoring CT scan, also known as coronary artery calcium (CAC) scan, detects calcium deposits in the coronary arteries. This test assesses the risk of coronary artery disease (CAD), which can lead to cardiovascular events such as angina, heart failure, and sudden cardiac arrest.A calcium-scoring CT scan is generally recommended for individuals at intermediate risk of CAD without symptoms. It includes:Men aged 40-75 and women aged 50-75: Especially those with a...

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)...

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...

The human body's intricate network of arteries ensures that every organ system receives the necessary oxygen and nutrients for optimal function. The arterial network in the head and neck region is particularly complex, providing vital blood flow to the brain, eyes, and other critical structures. Prominent arteries in this region include the internal carotid arteries and the vertebral arteries.
The internal carotid arteries supply blood to the anterior portion of the cerebrum. They enter the...

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...

Coronary Artery Disease (CAD) is a primary health risk worldwide, leading to significant morbidity and mortality. The condition arises from the buildup of atherosclerotic plaques within the coronary arteries, resulting in diminished blood supply to the heart muscle.The clinical manifestations of CAD vary widely, from asymptomatic stages to severe, life-threatening conditions. Understanding these manifestations is crucial for early diagnosis and effective management.Angina Pectoris: The Warning...
