概括

左心房 (LA) 功能恶化增加了老年人发展虚弱的风险. 这种关联特别与疲劳有关,突出了LA功能.

科学领域:

心脏病学心脏病学
老年学是一门学科.
心声回声扫描 (Echocardiography) 是一种心声回声扫描.

背景情况:

虚弱是患有心血管疾病的个体中普遍存在的疾病.
左心房 (LA) 功能受损是心血管疾病的确立危险因素.
减少LA功能和脆弱性之间的关系在很大程度上仍未被探索.

研究的目的:

调查左心房 (LA) 功能与老年人虚弱的发生率之间的关联.
为了确定LA功能的特定组件 (水库,管道,收缩应变) 或LA刚度是否预测事件脆弱性.

主要方法:

从社区动脉样硬化风险研究中分析了3292名非脆弱的老年人.
使用心声学测量左心房 (LA) 储,导管和收缩应变.
使用Fried脆弱现型和多变量逻辑回归评估事件脆弱性.

主要成果:

具有最低LA储压力的参与者患有脆弱的几率是2.42倍.
具有最高LA刚度指数的个体患有脆弱的几率是2.41倍.
更糟糕的LA功能与疲劳的增加显著相关,这是脆弱的一个组成部分.

结论:

左心房 (LA) 功能减弱独立地与较高的虚弱发病率有关.
较差的LA功能和脆弱性之间的关联与疲劳组成部分有关.
需要进一步的研究,以了解LA功能与脆弱发育之间的机制联系.

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...

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...
