概括

在高压阻塞性心肌病 (HOCM) 中,大内末素-1 (大ET-1) 水平升高与显著的心脏重塑有关,特别是左心房扩大. 这表明大ET-1在HOCM进展中起着关键作用.

科学领域:

心脏病学心脏病学
生物医学科学生物医学科学
医学研究医学研究

背景情况:

超大致阻塞性心肌病 (HOCM) 是一种复杂的心脏疾病.
心脏重塑,包括左心房扩大,是HOCM的一个重要特征.
特定生物标志物的作用,如大内甲蛋白-1 (大ET-1) 在HOCM相关的重塑需要进一步阐明.

研究的目的:

调查大ET-1水平与HOCM患者心脏重塑之间的关联.
确定大ET-1是否与心脏重塑的特定标志物相关,例如左心房扩大和心室缩.

主要方法:

对150名HOCM患者的回顾性分析.
根据心声学标准分类为正常左心房大小 (n=97) 和扩大左心房大小 (n=53) 组.
血大ET-1,NT-pro-BNP,HS-CRP和心磁共振成像 (CMR) 数据的测量.

主要成果:

与正常左心房患者相比,左心房扩大患者的Big ET-1和NT-pro-BNP水平显著更高.
升高的大ET-1与NT-pro-BNP,HS-CRP,左心房前直径和心室间隔膜厚度呈正相关性.
多重线性回归证实了大ET-1与NT-pro-BNP和左心房直径 (LADap) 的积极关联.

结论:

在左心房扩大HOCM患者中,大ET-1显著升高.
增加的大ET-1水平与HOCM中更明显的心脏重塑有关.
大ET-1可能在HOCM心脏重塑的发病过程中发挥关键作用.

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...
