概括

基于非侵入性定量流量比率 (QFR) 的功能性SYNTAX得分 (FSS/FSSII) 更好地分层了多血管疾病患者的风险. 这些得分减少了被归类为高风险患者的数量,提高了对主要心血管不良事件的预后准确性.

科学领域:

心脏病学心脏病学
干预心脏病学干预心脏病学
医疗成像医学成像

背景情况:

SYNTAX评分 (SS) 用于评估冠状动脉疾病的复杂性.
分流储备 (FFR) 固定的SYNTAX分数旨在改善风险分层.
需要使用非侵入性方法来评估在多血管疾病中的功能意义.

研究的目的:

在多血管冠状动脉疾病患者中,评估基于非侵入性定量流量比 (QFR) 的功能SYNTAX得分 (FSS I和FSS II) 的预后值.
为了比较QFR衍生得分与传统解剖学得分的风险分层表现.

主要方法:

一个单一中心的观察性研究包括160名患有多血管冠状动脉疾病的患者.
计算了SYNTAX评分I/II和基于QFR的功能SYNTAX评分I/II.
患者被跟踪1年,并分析了心脏死亡,心肌梗塞或缺血驱动的再血管化 (MACE) 的复合情况.

主要成果:

功能性SYNTAX评分 (FSS/FSSII) 将大量患者从高风险类别重新分类为中低风险类别.
与其他评分系统相比,FSSII与MACE (HR:1.069,p=0.002) 的相关性更强.
使用FSSII的重新计算降低了高风险组的无生存率,并增加了低风险组的无生存率.

结论:

基于QFR的功能SYNTAX得分 (FSS/FSSII) 可以减少高风险患者的比例,而不是与解剖SYNTAX得分相比.
与传统的评分系统相比,FSSII对风险分层和MACE的预测能力更强.
非侵入性FSSII在多血管冠状动脉疾病管理中提供了更好的预后价值.

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...

Acute Coronary Syndrome III: Diagnostic studies

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...
