- 心声回声扫描 (Echocardiography) 是一种心声回声扫描.
- 心脏衰竭研究研究
背景情况:
- 右心室 (RV) 功能的预后意义是在慢性心力衰竭 (HF) 中确立的.
- 关于VR功能在急性心力衰竭 (AHF) 中的作用的研究有限.
研究的目的:
- 调查急性左侧心力衰竭和减少喷射分数的患者RV功能障碍和扩张的预后价值.
- 确定该患者队列中不良心血管结果的独立预测因子.
主要方法:

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...

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...
