概括

在急性心力衰竭 (AHF) 中,RV无壁应变/PASP比TAPSE/PASP更好地预测结果. 这一新发现在AHF患者中具有特别重要的意义,AHF患者的喷射分数被保存.

科学领域:

心脏病学心脏病学
心声回声扫描 (Echocardiography) 是一种心声回声扫描.
心脏衰竭研究研究

背景情况:

右心室 - 肺动脉 (RV-PA) 合对于慢性心力衰竭的风险分层至关重要.
在急性心力衰竭 (AHF) 中对RV-PA合的数据有限.
对RV-PA合器的心声学评估有助于预测结果.

研究的目的:

评估RV-PA合替代品在AHF中的预后价值.
为了比较TAPSE/PASP和RV无壁应变/PASP比率的预测能力.
为了研究这些比率在AHF中的表现,减少与保留射出分数.

主要方法:

一个多中心的观察性研究,包括425名AHF患者.
心声学测量了肺动脉缩压 (PASP),三环状平面缩外流 (TAPSE) 和RV自由壁应变.
计算TAPSE/PASP和RV无壁应变/PASP比率作为RV-PA合替代品.

主要成果:

197名患者 (46.4%) 在180天后达到所有原因死亡/高风险住院的复合终点.
在多变量调整后,TAPSE/PASP和RV自由壁应变/PASP都是预后的独立预测因素.
与TAPSE/PASP相比,RV无壁应变/PASP表现出更好的歧视 (AUC为0.70对比0.66).
在保留喷射分数的AHF中,RV自由壁应变/PASP的优势更加明显.

结论:

RV无壁菌株/PASP是AHF预后的强大独立预测器.
无RV壁应变/PASP比TAPSE/PASP提供了优越的预后歧视,特别是在保留喷射分数的AHF中.
这些发现提高了对AHF管理中的RV-PA合的理解.

Imbalances in Cardiac Output

Imbalances in Cardiac Output

The heart's primary function is to pump blood throughout the body, maintaining a balance between blood sent out (cardiac output) and blood returning (venous return). If this balance is disrupted, it can result in congestive heart failure (CHF), a severe condition where the heart becomes an inefficient pump, leading to inadequate blood circulation.
CHF can occur due to the failure of either side of the heart. Left-side failure leads to pulmonary congestion—the right side continues to...

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...
