概括

在心房动 (AF) 患者中,左心房附属体排空速度 (LAAEV) 的降低是根据年龄,心力衰竭,AF类型,左心房直径和左心室喷射率预测的. 该模型有助于评估和管理非膜AF.

科学领域:

心脏病学心脏病学
医学诊断医学诊断医学诊断
预测建模预测建模

背景情况:

心房动 (AF) 是一种普遍的心律失常,增加了中风风险.
左心房附属体 (LAA) 是AF发展的关键.
降低LAA排空速度 (LAAEV) 表明非膜AF中的血栓形成风险和剥离后复发.

研究的目的:

在非膜性AF患者中确定影响LAAEV的因素.
为LAAEV开发一个预测模型.
改进非膜AF的评估和管理策略.

主要方法:

对1,048名非膜性AF患者进行了回顾性队列研究.
使用过胸腔和过食道心声学.
采用后勤和多重线性回归用于预测器识别和模型构建.

主要成果:

43.61%的患者减少了LAAEV (<40厘米/秒).
确定了LAAEV降低的独立预测因素:年龄,心力衰竭 (HF),AF类型 (持久/长期持久与偏激性AF),左心房直径 (LAD) 和左心室喷射率 (LVEF).
预测模型解释了43.5%的LAAEV差异.

结论:

年龄,HF,AF类型,LAD和LVEF是减少LAAEV的显著预测因素.
为LAAEV建立了一个经过验证的预测模型.
该模型可以协助对非膜AF患者的初始评估和治疗计划.

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 blood...
