概括
在急性缺血性中风 (AIS) 患者中,心脏中素 (cTn) 模式的上升表明死亡风险更高,结果较差. 这种动态变化,与稳定水平不同,表明急性心脏问题,需要密切监测.
科学领域:
- 心脏病学 心脏病学
- 神经学 神经学
- 生物标志物 生物标志物
背景情况:
- 心脏热素 (cTn) 升高在急性缺血性中风 (AIS) 中很常见,影响10-30%的患者,并与不良结果相关.
- 序列cTn测量区分了动态模式 (上升/下降>20%),表明急性心肌损伤与归因于慢性疾病的非动态模式.
研究的目的:
- 调查心脏托罗邦素 (cTn) 变化方向上升与下降对急性缺血性中风 (AIS) 患者的死亡率和功能结果的影响.
主要方法:
- 从5个中风中心对300名患有AIS和升高cTn的患者进行了回顾性分析,在48小时内进行了连续测量.
- cTn模式的分类是上升 (>20%的增加),下降 (>20%的减少) 或非动态 (≤20%的变化).
- 后勤回归用于评估cTn模式与7天死亡率和不良出院倾向之间的关联.
主要成果:
- 在72名患者中观察到cTn上升的模式,在66名患者中下降,在162名患者中观察到非动态的模式.
- 在54%的患者中,急性心肌梗塞被诊断为cTn上升,而在33%的患者中,cTn下降 (P<0.01).
- 与非动态模式相比,不断上升的cTn独立地与更高的7天死亡率 (aOR=32) 和不利的排泄倾向 (aOR=2.5) 相关.
结论:
- 患有急性缺血性中风 (AIS) 的患者心脏中热素 (cTn) 模式的上升是增加死亡率的独立预测因素.
- cTn水平的上升也与AIS患者不良的出院倾向有显著的关联.

Blood Studies for Cardiovascular System I: Cardiac Biomarkers
158
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...

Blood 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...
