通过Technetium-99m pyrophosphate (PYP) 成像,Transthyretin心肌粉症 (ATTR-CM) 诊断正在得到改善. 一个加拿大注册表显示ATTR-CM的流行率,并评估诊断得分的准确性.
科学领域:
- 心脏病学 心脏病学
- 核医学是一种核医学.
- 医疗成像医学成像
背景情况:
- 晶氨酸心肌粉症 (ATTR-CM) 是老年人心力衰竭的日益严重的原因.
- 技术-99m酸盐 (PYP) 成像是ATTR-CM的关键诊断工具.
- 创建了一个多中心的加拿大注册表来研究ATTR-CM的流行率和诊断准确性.
研究的目的:
- 为ATTR-CM研究建立一个多中心的加拿大注册表.
- 收集PYP扫描患者的临床和成像数据.
- 评估ATTR-CM诊断的不同风险评分的准确性.
主要方法:
- 包括来自加拿大4个中心的2,118名患者接受[99mTc]PYP成像.
- 收集病史,心脏粉症红旗和实验室生物标志物.
- 建立了ATTR-CM诊断,使用标准化标准和转移的非识别数据.
主要成果:
- 在29.2%的患者 (618/2118) 中诊断出ATTR-CM,5.3%的患者 (112/2118) 患有轻链氨基粉症.
- [99mTc]PYP扫描的数量从2016年到2022年大幅增加.
- 戴维斯和其他人. 风险评分显示,ATTR-CM诊断的准确性比Nitsche等人更高. 一个比分,一个分数.
结论:
- 收集了一大批具有详细临床和成像数据的患者队列.
- 该注册表为ATTR-CM诊断和管理研究提供了宝贵的资源.
- 该注册表正在不断增长,有望在未来对ATTR-CM的洞察力.

Pulmonary Angiogram
A Pulmonary Angiogram is an invasive procedure involving injecting a contrast medium through a catheter threaded into the pulmonary artery or the right side of the heart to visualize the pulmonary vasculature. Computed Tomography (CT) scans have mainly replaced this...

Definition and Purpose
An X-ray, or radiograph, is a non-invasive method that uses ionizing radiation to take images of internal structures. It is mainly used in cardiac imaging to examine the heart, lungs, and major blood vessels, aiming to identify abnormalities in the heart's size, shape, and position, such as heart failure, congenital defects, and vascular...
