概括

将蛋白质组学与传统风险因素相结合,可以改善加速冠状动脉斑块进展和高风险斑块发展的预测. 这种方法增强了心血管风险分层,而不需要重复成像扫描.

科学领域:

心血管成像和诊断系统
蛋白质组学和生物标志物发现发现
翻译性心血管研究

背景情况:

冠状动脉计算机断层扫描血管图 (CCTA) 可视化动脉样硬化斑块负担和组成.
斑块的进展是心血管事件的一个关键因素.
重复的CCTA扫描是资源密集的,需要非侵入性方法来跟踪斑块的进展.

研究的目的:

评估将蛋白质组学与传统风险因素相结合的疗效,以识别加速斑块进展的患者.
评估蛋白质面板对高风险斑块发育的预测价值.

主要方法:

一项长期随访研究涉及97名参与者,他们接受了两次CCTA扫描和血蛋白质组学分析.
加快的斑块进展定义为百分比动脉瘤体积 (PAV),百分比非化斑块体积 (NCPV) 和百分比化斑块体积 (CPV) 的中位数.
通过积极重塑或低密度斑块识别的高风险斑块 (HRP);在预测模型中纳入重要的蛋白质.

主要成果:

添加蛋白质面板显著改善了曲线下的面积 (AUC) 预测加速PAV进展 (0.830到0.909,P=0.023) 和NCPV进展 (0.685到0.825,P=0.008).
高风险斑块发育的AUC也从0.791增加到0.860与蛋白质面板 (P=0.036).
在化斑块体积进展方面没有观察到显著的改善.

结论:

将蛋白质组学与传统的风险因素相结合,可以更好地预测斑块的加速进展和高风险斑块的发展.
这种综合方法可以改善心血管风险分层.
在不需要重复的CCTA检查的情况下,有可能指导治疗决策.

Imaging Studies for Cardiovascular System VI: Calcium -Scoring CT

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...

Blood Studies for Cardiovascular System II: CRP, Hcy, and Cardiac Natriuretic Peptide Markers

Blood Studies for Cardiovascular System II: CRP, Hcy, and Cardiac Natriuretic Peptide Markers

Cardiac biomarkers are critical in diagnosing, prognosing, and managing cardiovascular diseases. Routine measurement of specific biomarkers such as B-type natriuretic peptide (BNP), C-reactive protein (CRP), and homocysteine (Hcy) is common practice in clinical settings to evaluate heart function and predict cardiovascular events.
These markers indicate stress or strain on the heart muscle:
Natriuretic Peptides (BNP)
Cardiac myocytes produce these hormones in response to ventricular stretching...

Blood Studies for Cardiovascular System I: Cardiac Biomarkers

Blood Studies for Cardiovascular System I: Cardiac Biomarkers

Cardiac biomarkers are enzymes, proteins, and hormones released into the blood when cardiac cells are injured. They are powerful tools for triaging.
The essential diagnostic tools for detecting myocardial necrosis and monitoring individuals suspected of having acute coronary syndrome (ACS) include:
Troponins
Troponins, particularly cardiac troponins I and T, are the most precise and sensitive markers of myocardial injury. They are detectable within 4-6 hours of myocardial injury and remain...
