概括
心脏移植 (HT) 后生物标志物升高预测结果不佳. 在HT后24小时的N-终端B型亲尿素 (NT-proBNP) 水平在识别患有死亡或移植失败风险的患者中具有高度准确性.
科学领域:
- 心脏病学 心脏病学
- 移植医学 移植医学
- 生物标志物研究 生物标志物研究
背景情况:
- 心脏移植 (HT) 给人带来很大的生理压力,导致分析生物标志物的可测量变化.
- 监测这些生物标志物对于评估患者康复和移植后潜在并发症至关重要.
研究的目的:
- 调查心脏移植后生物标志物水平是否可以预测患者的预后.
- 确定特定的生物标志物,这些生物标志物表明死亡风险较高或严重的初级移植缺陷 (PGF).
主要方法:
- 这是一项对149名心脏移植接受者进行的前性纵向研究.
- 生物标志物水平 (高灵敏性热素T,NT-proBNP,肌素,乳酸) 在HT前和HT后多个时间点测量,最多在HT后96小时.
- 主要结局:死亡和严重PGF的组合.
主要成果:
- 生物标志物水平,特别是NT-proBNP和热素,在HT后仍然很高,在24-72小时内稳定下来.
- 所有分析的生物标志物都与复合结果 (死亡或严重的PGF) 有显著的关联.

Cardiac biomarkers are enzymes, proteins, and hormones released into the blood when cardiac cells are injured. They are powerful tools for triaging.
The essential diagnostic tools for detecting myocardial necrosis and monitoring individuals suspected of having acute coronary syndrome (ACS) include:
Troponins
Troponins, particularly cardiac troponins I and T, are the most precise and sensitive markers of myocardial injury. They are detectable within 4-6 hours of myocardial injury and remain...

Cardiac biomarkers are critical in diagnosing, prognosing, and managing cardiovascular diseases. Routine measurement of specific biomarkers such as B-type natriuretic peptide (BNP), C-reactive protein (CRP), and homocysteine (Hcy) is common practice in clinical settings to evaluate heart function and predict cardiovascular events.
These markers indicate stress or strain on the heart muscle:
Natriuretic Peptides (BNP)
Cardiac myocytes produce these hormones in response to ventricular stretching...
