概括
大脑脊髓液肌酸激酶BB异酶 (CSF CK-BB) 可靠地预测了针对性温度管理 (TTM) 治疗心脏骤停幸存者的不良神经结果. 230U/L的CSF CK-BB水平为不良结果提供100%的特异性.
科学领域:
- 神经学 神经学
- 生物标志物 生物标志物
- 关键护理医学 关键护理医学
背景情况:
- 大脑脊髓液肌酸激酶BB异酶 (CSF CK-BB) 是心脏骤停 (CA) 后潜在的预后生物标志物.
- 以前的研究显示出高预测价值,但在现代护理中缺乏评估,包括有针对性的温度管理 (TTM).
研究的目的:
- 评估CSF CK-BB的预后价值,以预测TTM治疗的患者在CA后的神经结果.
- 确定最佳的CSF CK-BB值,以预测不良的神经结果.
主要方法:
- 214名昏迷的CA患者 (2010-2020年) 的回顾性队列研究,用CSF CK-BB测定 (CA后36-84小时).
- 在医院出院时使用大脑性能类别 (CPC) 评分评估的神经结果 (1-3有利/中等,4-5差).
- 评估了双边缺少体感唤起潜能 (SSEPs) 的附加值.
主要成果:
- CSF CK-BB ≥230 U/L预测了100%的特异性和69%的灵敏度的糟糕结果.
- 将CSF CK-BB与缺席的SSEP结合起来,使灵敏度提高到80%,同时保持100%的特异性.
- 只有9%的患者醒过来;13%的患者表现出不一致的CK-BB和SSEP发现.
结论:
- CSF CK-BB 是一个准确的预测器,可预测CA幸存者治疗TTM时的神经结果不佳.

136
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...

01:19Blood Studies for Cardiovascular System II: CRP, Hcy, and Cardiac Natriuretic Peptide Markers

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...
