概括
净水摄入 (NWU),一种用于急性缺血性中风 (AIS) 的新型成像指标,显示了与90天结果的ASPECTS可比的预测性能. 这种快速的,自动化的指标可能有助于指导AIS治疗.
科学领域:
- 神经学 神经学
- 放射学 放射学是一门学科.
- 医疗成像医学成像
背景情况:
- 对于急性缺血性中风 (AIS) 中心脏病特征和再输效益的传统理解可能是不完整的.
- 阿尔伯塔中风计划早期CT分数 (ASPECTS) 显示出显著的评级者之间的变化.
- 重灌疗法可以使AIS患者受益,不论其ASPECT.
- 需要新的,可重现的成像指标来指导AIS治疗.
研究的目的:
- 评估净水摄入量 (NWU),一种新的非对比计算断层扫描 (NCCT) 度量,用于预测AIS患者的临床结果.
- 将NWU的预测性能与ASPECTS进行比较.
- 评估NWU在确定治疗益处方面的实用性.
主要方法:
- 利用从11个经过认证的中风中心对AIS患者进行前性收集的注册表数据.
- 通过自动比较NCCT上脑部的ipsilateral和contralateral区域的密度来计算NWU.
- 采用多变量回归模型来预测90天修改的兰金尺度 (mRS) 结果,使用NWU与ASPECTS.
- 根据年龄,NIHSS,tPA和内血管治疗进行调整的模型.
主要成果:
- 基于NWU的模型对90天mRS结果的基于ASPECTS的模型进行了可比的预测性能 (AUROC 0.749与0.732,p=0.513).
- 在子组中观察到类似的表现,包括患有大心脏病核心的患者 (AUROC 0.863 vs 0.795) 和晚期时间窗口中的患者 (AUROC 0.677 vs 0.638).
结论:
- 净吸水量 (NWU) 是一个快速,可自动计算的NCCT指标.
- 在预测AIS中的90天功能结果方面,NWU的表现与ASPECTS相当.
- 新北大学显示出作为可靠的成像生物标志物指导AIS管理的潜力.

1.2K
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...
