概括

过导管大动脉置换 (TAVR) 后左心室喷射率 (LVEF) 的急性恶化是常见的,但不会影响存活率. LVEF通常在术后一个月内恢复.

科学领域:

心脏病学心脏病学
干预心脏病学干预心脏病学
心声回声扫描 (Echocardiography) 是一种心声回声扫描.

背景情况:

常常观察到左心室喷射分数 (LVEF) 在透气管后的大动脉置换 (TAVR) 后恶化.
在TAVR后急性LVEF下降的临床意义仍然不确定.

研究的目的:

调查TAVR后急性LVEF恶化的发生率和影响.
确定LVEF下降的预测因素,并评估其对患者存活时间的影响.

主要方法:

从2016年1月到2022年5月,连续接受TAVR的患者的分析.
根据LVEF下降 (≥5%) 进行分类的患者在出院时.
对生存率和用于预测因子识别的后勤回归进行比较.

主要成果:

25.5%的患者在TAVR后出现LVEF恶化,特别是那些基线LVEF≥50%的患者.
基线LVEF是LVEF恶化的唯一独立预测因素 (OR=1.06).
一个月后,LVEF下降得到解决,群体之间没有显著的生存差异.

结论:

在TAVR后急性LVEF恶化是常见的,但是短暂的,在一个月内恢复.
这种LVEF变化不会对长期存活率产生不利影响.
后TAVR回声心脏图的重点应该从急性LVEF变化转移到其他参数.

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...
