概括
严重的大动脉狭窄患者通常具有多器官功能障碍,液体过载和异常生物标志物表明. 这种功能障碍显著恶化了跨导管大动脉植入 (TAVI) 后的结果,突出了需要更好的管理策略.
科学领域:
- 心脏病学 心脏病学
- 生物标志物 生物标志物
- 器官功能障碍 器官功能障碍 器官功能障碍
背景情况:
- 严重的大动脉狭窄 (AS) 是一种严重的疾病,通常是晚期诊断的,即使是先进的诊断,也会导致心力衰竭.
- 门置换是标准的治疗方法,但由于晚期诊断和晚期疾病,患者的结果仍然令人担忧.
研究的目的:
- 用血液生物标志物评估严重AS患者的多器官功能障碍.
- 调查定量流体水平与跨导管大动脉植入后 (TAVI) 临床结果之间的关联.
主要方法:
- 评估了880名接受TAVI的严重AS患者,具有预干预血清生物标志物概况.
- 使用生物电阻谱法 (切断值≥1.0 L) 量化液体过载 (FO).
- 监测的复合主终点:第一次心力衰竭住院治疗或死亡.
主要成果:
- 41%的患者患有FO,89%的患者在多个器官领域显示生物标志物异常.
- 液体水平与肌细胞应激,肝/功能障碍,炎症和贫血的生物标志物相关.
- 每个额外的受影响器官域都将事件危险增加71% (调整HR: 1.71).
结论:
- 生物标志物异常在严重的AS中很常见,由拥堵加剧,并预测TAVI后的预后较差.
- 在严重的AS患者中,多器官功能障碍与显著更差的临床结果有关.
- 扭曲的生物标志物和流体过载的组合构成最高风险.

Imbalances in Cardiac Output
1.3K
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
1.5K
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...

Tissue Transplantation
332
Tissue transplantation is a significant medical procedure involving the transfer of cells, tissues, or organs from a donor to a recipient, with the primary aim of restoring lost functions. This procedure is crucial in treating a broad spectrum of diseases, including kidney diseases, liver failure, heart disease, and certain types of cancers.
