心血管成像 - 心血管成像
心脏衰竭研究研究

背景情况:

左心房 (LA) 应变反映了左心室功能,是心力衰竭的潜在预测因素.
ST升高心肌梗塞 (STEMI) 是一种关键性疾病,需要准确的预后标志物.
评估LA水库菌株对STEMI后的长期结果的影响至关重要.

研究的目的:

评估LA储菌株在预测STEMI后的长期心力衰竭事件中的预后价值.
为了确定LA储菌株是否改善STEMI患者的风险分层.

主要方法:

在287名STEMI患者中使用二维斑点跟踪回声心脏图测量LA储菌株.
患者被按LA储菌株四分位数分层.
考克斯回归分析确定了复合心力衰竭终点 (心脏死亡,住院,新发性心力衰竭) 的预测因素.

主要成果:

较低的LA储菌株与年龄较大和左下心室喷射率 (LVEF) 有关.
心力衰竭事件的独立预测因素包括较高的年龄,较低的LVEF,较低的透析血压和较低的LA储压力.
将LA水库应变纳入风险模型显著提高了预测性能 (C-统计数据为0.838对比0.784).

结论:

在STEMI幸存者中,LA储菌株为长期心力衰竭结果提供了增量预后价值.
这一发现支持在对STEMI后患者的风险评估中使用LA储菌株.

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...
