概括

射频导管切除可显著改善左心房功能,在患有心房发症的患者. 那些心力衰竭和保留喷射分数的人在剥离后表现出更大的功能改善.

科学领域:

心脏病学心脏病学
电子生理学电子生理学
心脏衰竭研究研究

背景情况:

在阳性心房动 (PxAF) 患者的射频导管切除 (RFCA) 后,左心房 (LA) 功能变化尚未完全理解.
同时存在的心力衰竭与保存的喷射分数 (HFpEF) 对RFCA后LA功能恢复的影响需要进一步调查.

研究的目的:

为了比较RFCA后PxAF患者的LA功能的改善,HFpEF的概率高和不高.
评估HFpEF概率与RFCA后LA功能恢复之间的关联.

主要方法:

在基线和RFCA后3个月内对LA体积指数 (LAVI),LA排空分数 (LAEF) 和LA峰值储应变 (LA RS) 的心声评估.
经过RFCA的PxAF患者根据H2FPEF得分被分为高 (hp-HFpEF) 和低/中 (lp-HFpEF) 的概率组.
统计分析比较了两组LA功能参数的变化,并对混因素进行了调整.

主要成果:

基线LA功能在hp-HFpEF和lp-HFpEF组之间显著不同 (LAVI,LAEF,LA RS的P<0.01).
与lp-HFpEF患者相比,hp-HFpEF患者在LAEF和LARS中表现出显著更大的改善,并在RFCA后3个月内LAVI的减少更大.
高FpEF的高概率与RFCA后增强的LA功能改善独立相关.

结论:

在PxAF患者中,RFCA导致LA功能显著改善.
患有HFpEF高概率的患者在RFCA后经历了更实质性的LA功能恢复,相比较于较低概率的患者.
这些发现凸显了RFCA对PxAF患者同时出现HFpEF的LA重塑的潜在益处.

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...
