概括
常见的心脏粉症 (ATTR-CA) 常见于心力衰竭患者,心力衰竭患者常见于心力衰竭患者,心力衰竭患者常见于心力衰竭患者. 然而,这项研究揭示了ATTR-CA在心力衰竭中显著的发病率与减少喷射率 (HFrEF) 患者,表明需要更广泛的临床怀疑.
科学领域:
- 心脏病学 心脏病学
- 心血管疾病 心血管疾病
- 氨基粉症是什么?
背景情况:
- 常见的Transthyretin心脏氨基粉症 (ATTR-CA) 与心力衰竭与保存的喷射分数 (HFpEF) 有关.
- 在心功能受损的患者中,ATTR-CA的表现不太清楚.
- 调查ATTR-CA中的多种心力衰竭 (HF) 表型对于诊断至关重要.
研究的目的:
- 在ATTR-CA诊断时确定不同心力衰竭 (HF) 现型的流行率.
- 在ATTR-CA患者中确定与每个HF表型相关的临床特征.
主要方法:
- 从2016年2月到2022年12月连续ATTR-CA患者的回顾性队列研究.
- 人口统计,并发症,成像和实验室检测结果在HF表型之间的比较:HFpEF,心力衰竭与轻微减少的射出分数 (HFmrEF) 和心力衰竭与减少的射出分数 (HFrEF).
主要成果:
- 在ATTR-CA患者中,HFpEF (60.6%),HFrEF (21.6%) 和HFmrEF (17.8%) 呈现.
- 患有HFrEF或HFmrEF的患者更有可能是非洲裔美国人.
- 与HFpEF相比,HFrEF/HFmrEF组表现出较差的NYHA类,较高的NT-proBNP和较高的血清肌素.
结论:
- 在HFrEF中,ATTR-CA比先前的假设更为普遍,不管喷射分数如何,临床怀疑是必要的.
- 虽然并发症相似,但HFmrEF和HFrEF患者的症状负担更大.

Pathophysiology of Heart Failure
1.5K
Heart failure (HF) is a progressive syndrome involving ventricles that leads to inadequate cardiac output. It can be classified based on location and output or ejection fraction. Ejection fraction (EF) is an essential measurement in the diagnosis and surveillance of HF. Reduced EF corresponds to systolic heart failure (HFrEF). However, HF with preserved ejection fraction (HFpEF) is becoming increasingly prevalent. Also known as diastolic HF, this form of HF is related to aging. The...

Amyloid Fibrils
9.3K
Amyloid fibrils are aggregates of misfolded proteins. Under most circumstances, misfolded proteins are either refolded by chaperone proteins or degraded by the proteasome. However, in the case of a mutation or a disease, these proteins can accumulate to form large clusters and often further assemble to form elongated fibers, called fibrils.
Amyloid deposits were observed as early as 1639 in the liver and the spleen. In 1854, Rudolph Virchow performed iodine staining,...

Heart Failure Drugs: Inhibitors of Renin-Angiotensin System
405
The activation of the sympathetic nervous system and the renin-angiotensin-aldosterone system (RAAS) contributes to cardiac remodeling, and inhibiting the RAAS is a pharmacological target in heart failure management. As a result, neurohumoral modulation is a crucial treatment principle for managing heart failure. This approach involves using medications like ACE inhibitors (ACEIs), angiotensin receptor blockers (ARBs), β-blockers, mineralocorticoid receptor antagonists (MRAs), and neutral...

Imaging Studies for Cardiovascular System III: X-Ray
160
The most common cardiovascular diagnostic test is an X-ray. It produces images of the heart, blood vessels, and adjacent structures.
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...
