概括
此摘要是机器生成的。与侵袭性冠状动脉血管学相比,对稳定的胸痛进行CT-first的策略增加了功能测试,并减少了再血管化和并发症. 经过3. 5年,心脏病发病率的结果是相似的.
科学领域
- 心脏病学
- 诊断成像

背景情况
- 怀疑冠状动脉疾病的稳定胸痛需要有效的诊断策略.
- 侵袭性冠状动脉扫描 (ICA) 是一种标准的诊断和治疗工具,但存在风险.
- CT冠状动脉扫描 (CTCA) 为评估冠状动脉提供了一个非侵入性的替代方案.
研究的目的
- 将CTCA-first和ICA-first战略之间的功能测试和管理结果进行比较.
- 评估该策略对稳定胸痛和低至中等CAD概率的患者的复发症和胸痛的影响.
主要方法
- 预期多中心DESCHARGE试验的二次分析 (NCT02400229).
- 在3414名参与者中随机比较CTCA-first与ICA-first策略.
- 在3. 5年内评估的结果包括功能测试率,再血管化,主要并发症和心痛,按CAD严重程度分层.
主要成果
- 在没有高风险解剖的情况下,CTCA-first的功能测试显著增加 (53.3%对24.3%).
- 在具有高风险解剖 (58. 2% vs. 82.1%) 和没有高风险解剖 (37. 9% vs. 59. 6%) 的阻塞性CAD中,CTCA-first的复血管化率较低.
- 与ICA-first相比,CTCA-first导致较少的严重并发症和类似的心痛率.
结论
- 在稳定的胸痛患者中,CTCA-first策略增加了功能测试,减少了重血管化和重大并发症.
- 冠状动脉疾病的严重程度影响了CTCA-first的好处.
- 在3. 5年的随访期内,CTCA-first显示出与ICA-first相比的胸痛率.

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...
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 catheterization is an invasive diagnostic technique used to identify and evaluate structural and functional diseases of the heart and major blood vessels. This technique diagnoses congenital heart disease, coronary artery disease, valvular heart disease, and coronary spasms and assesses ventricular function. It helps guide treatment decisions, including the need for revascularization procedures like percutaneous coronary intervention (PCI) or coronary artery bypass grafting (CABG) and...
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...
Left heart catheterization is an invasive diagnostic procedure used to evaluate the function and structure of the left side of the heart. It is generally performed to diagnose and treat cardiovascular conditions such as valve abnormalities, coronary artery disease, and congenital heart defects.Diagnostic and therapeutic purposesLeft heart catheterization serves various diagnostic and therapeutic purposes, including:Assessing coronary artery bypass grafts.Evaluating coronary artery disease in...
