概括
周围动脉疾病 (PAD) 单独不会增加主要不良心血管事件 (MACE) 的风险. 心肌输液异常,而不是PAD本身,是这些患者风险分层的关键.
科学领域:
- 心脏病学 心脏病学
- 血管医学 血管医学
- 核心脏病学 核心脏病学
背景情况:
- 冠状动脉疾病 (CAD) 和外周动脉疾病 (PAD) 具有共同的风险因素,并与主要不良心血管事件 (MACE) 有关.
- 除了共同的病理生理学和心肌输液异常之外,PAD对MACE风险的独立贡献仍然不清楚.
研究的目的:
- 为了确定PAD是否独立地提高MACE风险,或者这是否归因于心肌输液异常.
- 调查PAD患者中MACE风险的特定媒介.
主要方法:
- 分析了来自国际登记处的45252名患者,这些患者接受了SPECT心肌输液成像.
- 使用总 perfusion deficit (TPD) 来量化心肌输液异常.
- 倾向性得分匹配以比较患有PAD和没有PAD的患者之间的MACE风险,调整以考虑混因素.
主要成果:
- 在倾向性得分匹配后,单独患有PAD的病史与MACE风险增加没有独立相关 (P = 0.064).
- 孤立的CAD比孤立的PAD (aHR,1.20) 具有更高的MACE风险 (aHR,1.92).
- 同时的CAD和PAD显示出与孤立的CAD相似的MACE风险 (aHR,1.57).
结论:
- 当心肌输液异常和其他因素被考虑时,PAD本身不是MACE的独立预测因素.
- 评估心肌缺血负担对于PAD患者的准确风险分层至关重要.
- 建议根据缺血性负担对PAD患者立即启动疾病修饰疗法.

Imaging Studies for Cardiovascular System I:Echocardiography
273
Cardiac imaging studies encompass a wide range of noninvasive and minimally invasive techniques designed to visualize the heart's structure and function in detail. One such technique is echocardiography, which uses high-frequency ultrasound waves to produce detailed images of the heart, known as echocardiograms.
Indications: Echocardiography is utilized to diagnose heart failure, valve disorders, and myocardial infarction. It also assesses cardiac structures' size, shape, and motion,...

Assessment of the Cardiovascular System I: Subjective Data
244
A thorough health history and physical assessment are essential for identifying cardiovascular disease (CVD) symptoms and distinguishing them from other health issues.
Initial Enquiry
Ask the patient about their primary concern and thoroughly explore all reported symptoms.
Medical History
Investigate past illnesses affecting the cardiovascular system, such as angina, anemia, rheumatic fever, congenital heart disease, stroke, thrombophlebitis, dysrhythmias, varicosities
Inquire about symptoms...
