- 确定与冠状动脉斑块特征相关的特定CGM指标和葡萄糖动态组件.
主要方法:
- 分析了14个CGM衍生指数 (例如,每日平均风险比 (ADRR),自相关度量 (AC_Mean, AC_Var)) 和常规措施 (禁食血糖 (FBG),HbA1c,120分钟血葡萄糖 (PG120)).
- 评估冠状动脉斑块脆弱性,特别是死核 (%NC),使用虚拟组织学-血管内超声波.
- 应用因子分析来识别葡萄糖动态的潜在组成部分及其与%NC的关联.
- 在来自日本,美国和中国的独立数据集中验证发现.
主要成果:
- 来自CGM的指数,特别是ADRR和AC_Var,与FBG,HbA1c和PG120相比,显示了%NC的优异预测.
- 因子分析揭示了葡萄糖动态的三个独立组成部分 (平均值,方差,自相关性),每一个都与%NC相关.
- ADRR反映了平均值和方差组件;AC_Var主要反映了自相关性,而传统措施主要反映了平均值组件.
结论:
- 反映葡萄糖动态的平均值,方差和自相关性的CGM衍生指数对于CAD风险查是有效的.

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...

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...
