概括

通过三环状平面缩外流 (TAPSE) 测量右心室功能,是心力衰竭与减少喷射率 (HFrEF) 的关键预测因素. 较高的TAPSE表明心力衰竭恶化的风险较低,住院和死亡.

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:

左心室喷射分数 (LVEF) 在慢性心力衰竭和减少喷射分数 (HFrEF) 中具有有限的预后价值,特别是在中度至严重的减少的情况下.
右心室 (RV) 功能参数可能与HFrEF患者的不良临床事件相关.

研究的目的:

调查HFrEF中RV功能参数与不良临床结果之间的关联.
评估RV功能对恶化心力衰竭 (WHF) 住院,心血管死亡和全因死亡率的预测价值.

主要方法:

对164名HFrEF患者进行的前性单中心队列研究.
供应商独立的后处理软件用于回声心电图电影循环分析.
对临床和LVEF参数进行调整的多变量考克斯回归分析.

主要成果:

较高的三环状平面缩外流 (TAPSE) 与WHF住院率的降低 (HR 0.880) 和WHF住院心血管死亡 (HR 0.878) 或所有原因死亡 (HR 0.918) 的复合终点显著相关.
这些关联在LVEF≤35%的患者中更为明显.
对于不良结果,TAPSE证明了独立的预后价值.

结论:

三环状平面缩外流 (TAPSE) 是HFrEF患者不良临床结果的独立预测器.
需要进一步的研究来评估将TAPSE纳入风险得分是否提高了诊断准确度.

关键词:

这就是HFrEFEF.慢性心力衰竭是一种慢性心力衰竭.右心室功能的功能.

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...

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 send...
