概括
术前冠状动脉周周脂肪减弱指数 (FAI) 和甘油三糖体质指数 (TyG-BMI) 可以预测经过PCI的慢性冠状动脉综合征患者的周周心脏梗塞 (PMI) 和主要心血管不良事件 (MACE).
科学领域:
- 心脏病学 心脏病学
- 放射学 放射学是一门学科.
- 生物标志物 生物标志物
背景情况:
- 经过皮肤冠状动脉干预 (PCI) 的慢性冠状动脉综合征 (CCS) 患者有患周围手术心肌梗塞 (PMI) 和主要心血管不良事件 (MACE) 的风险.
- 确定这些不良结果的预测生物标志物对于风险分层和管理至关重要.
研究的目的:
- 评估PCI前周冠状动脉脂肪减弱指数 (FAI) 和甘油三糖体质指数 (TyG-BMI) 的预测值,用于CCS患者的PMI和MACE.
主要方法:
- 对476名接受选择性PCI的CCS患者进行前性观察性研究.
- 通过冠状动脉CT血管造影 (CCTA) 测量FAI;根据实验室测试计算TyG-BMI.
- 按PCI后的热素水平定义的PMI;MACE包括心血管死亡,心脏病发作,静脉复缩和再血管化.
主要成果:
- 在23.9%的参与者中,PMI发生.
- 较高的TyG-BMI和较少的负面FAI得分与PMI相关 (P < .001).
- 与单独的临床变量 (AUC 0.67) 相比,FAI,TyG-BMI和临床变量的综合模型显示出更好的预测 (AUC 0.72).
- 高的TyG-BMI和FAI> -70.1 HU预测了最高的MACE率 (P < .001).
结论:
- 手术前的FAI和TyG-BMI是PCI患者中PMI和MACE的独立预测因素.
- 这些成像和代谢标记可以增强对这一群体的风险评估.

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...

Cardiac computed tomography (CT) scanning is an advanced cardiac imaging technique that utilizes CT technology, with or without intravenous (IV) contrast, to produce accurate cross-sectional virtual slices of specific areas of the heart, coronary circulation, and major blood vessels such as the aorta, pulmonary veins, and arteries. The computer processes these slices to generate three-dimensional images. Multidetector CT (MDCT) is a rapid form of CT scanning that captures multiple slices...

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...
