概括
在COVID-19的CT扫描中发现的偶然冠状动脉 (iCAC) 可能表明未来的心脏病发作风险. 早期发现和治疗ICAC对于预防心血管事件至关重要.
科学领域:
- 心脏病学
- 放射学
- 传染性疾病
背景情况:
- COVID-19 可能导致低氧化,需要像胸部CT这样的成像.
- 医学成像中的偶然发现,如冠状动脉 (CAC),是常见的.
- 在COVID-19患者中偶然检测到的CAC的临床意义尚未得到充分确立.
研究的目的:
- 强调在COVID-19评估期间检测到的偶然冠状动脉 (ICAC) 的重要性和采取行动.
- 为了强调未经治疗的ICAC与随后的急性心肌梗塞 (AMI) 之间的潜在联系.
主要方法:
- 一份病例报告详细介绍了一名患有COVID-19和低氧血症的病例.
- 对非对比性胸部CT扫描进行审查,该扫描显示了磨砂玻璃的不透明度和中度的ICAC.
- 在没有针对ICAC的特殊治疗的情况下,分析患者在出院后的临床过程.
主要成果:
- 一名患有COVID-19的58岁男子在胸部CT上发现了中度的ICAC,但没有对这一发现进行后续检查就被送出院.
- 在出院18个月后, 患者出现了急性心肌梗塞.
- 这种情况表明未被解决的ICAC与未来的心脏事件之间存在潜在的关联.
结论:
- 在COVID-19的胸部CT检测中发现的偶发冠状动脉也不能被忽视.
- 如果不治疗iCAC,可能会导致心血管不良结果,包括心肌梗塞.
- 在急性呼吸道疾病的背景下,需要对偶发性CAC进行管理.

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...

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...

Coronary Artery Disease (CAD) originates from a series of events that impair the function of coronary arteries, the blood vessels responsible for delivering oxygen-rich blood to the heart muscle. The pathophysiology of CAD is closely linked to atherosclerosis, a chronic inflammatory and lipid-driven condition affecting the vascular endothelium.1. Endothelial DamageThe process begins with damage to the vascular endothelium, which serves as a protective barrier between the blood and the vessel...

Interprofessional care for coronary artery disease includes pharmacological therapy and revascularization procedures.Pharmacological therapy for Coronary Artery Disease (CAD) aims to manage symptoms, prevent complications, and improve patient outcomes through various classes of medications:Antiplatelet Agents:Aspirin and Clopidogrel: These medications inhibit platelet aggregation, preventing blood clots, which is crucial for avoiding heart attacks and strokes. Doctors often prescribe these...

Effective preventive measures for coronary artery disease (CAD) focus on controlling modifiable risk factors, including cholesterol abnormalities and lifestyle changes.Cholesterol ManagementFirst, the Mediterranean diet and the American Heart Association advocate for maintaining low-density lipoprotein (LDL) cholesterol levels below 100 mg/dL, with a more stringent recommendation of below 70 mg/dL for individuals at high risk. LDL cholesterol, often termed "bad cholesterol," can lead to the...

Diagnosing acute coronary syndrome or ACS begins with a thorough patient history. Notable symptoms include central, crushing chest pain radiating to the left arm, neck, jaw, or back, along with shortness of breath, sweating (diaphoresis), nausea, vomiting, dizziness, and palpitations.It is crucial to note any history of cardiac illnesses and assess risk factors, including age, gender, smoking, hypertension, diabetes, hyperlipidemia, and a sedentary lifestyle.During physical examination, vital...
