概括

循环中的基因组,特别是H2A,在心力衰竭患者中表现出不同的血形状,其中包括心力衰竭患者的保留喷射分数 (HFpEF) 和心力衰竭患者的减少喷射分数 (HFrEF). 这种液体活检方法有助于诊断HF并区分HFpEF和HFrEF.

科学领域:

心血管医学心血管医学
生物标志物发现发现
分子诊断学分子诊断

背景情况:

由于当前诊断工具的局限性,用保存的喷射分数 (HFpEF) 诊断心力衰竭是具有挑战性的.
循环组织蛋白是炎症和中风的新兴生物标志物,这表明它可能在其他心血管疾病中发挥作用.
显著的血基因组形状可能为心力衰竭 (HF) 诊断和亚型化提供新的途径.

研究的目的:

在患有HFpEF,减少喷射分数 (HFrEF) 的HF患者和健康个体中调查循环中的基因组和基因组复合体概况.
为了确定特定的基因素配置文件是否可以区分HFpEF和HFrEF.
为了评估血组织素水平的诊断潜力,作为心力衰竭的液体活检.

主要方法:

分析了来自30名健康个体,22名HFpEF患者和25名HFrEF患者的血样本.
基于ImageStreamX的检测被用来量化循环中的核心质子 (H2A,H2B,H3,H4) 和质子变体 (宏H2A1.1,宏H2A1.2).
通过统计分析,在三组中比较了基因组和基因组复合物的水平.

主要成果:

与健康对照人群相比,大多数循环中的基因组和基因组复合体在HFpEF和HFrEF患者中都升高.
与健康个体 (p=0.002) 和HFrEF患者 (p=0.00008) 相比,Histone H2A在HFpEF患者中显著升高.
升高的H2A水平与左心室喷射率 (EF) (r=0.493) 有正相关性.

结论:

显著的血基因组形状,特别是高的H2A,可以帮助检测心力衰竭.
这种基因组样本分析方法在区分HFpEF和HFrEF方面表现有前途.
高通量成像流细胞计适应液体活检为HF诊断和亚型化提供了一种新的方法.

Pathophysiology of Heart Failure

Pathophysiology of Heart Failure

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...

Imaging Studies for Cardiovascular System III: X-Ray

Imaging Studies for Cardiovascular System III: X-Ray

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...
