- 神经学 神经学
- 生物标志物研究 生物标志物研究
- 临界护理医学 临界护理医学
背景情况:
- 心脏骤停后 (CA) 患者经常处于昏迷状态,需要精确的神经预测.
- 目前的指导方针建议进行多式评估,包括神经元特异性酶 (NSE).
- 神经纤维光链 (NFL) 显示出早期和更准确的预后潜力,与NSE相比,混因素更少.
研究的目的:
- 在常规临床实践中调查血清NFL的预后价值.
- 为了比较NFL的准确性与既有的神经预测测试.
- 评估NFL在预测CA后神经结果中的实用性.
主要方法:
- 在152名患者的回顾性观察研究中,血清NFL测量在CA后24-96小时内.
- 在医院出院时使用大脑性能类别 (CPC) 评分评估的神经结果.
- 使用SIMOA Quanterix测定用于NFL的NFL,NSE,EEG,SSEP和CT头的预后性能比较.
主要成果:
- NFL>2000 pg/ml预测了100%的特异性,导致神经系统的不良结果.
- 在69%的患者中,低NFL度 (<55 pg/ml) 与良好的结果有关.
- 根据NFL的分析,预测准确度很高 (AUC为0.89),比其他测试检测出了16-41%的不良结果患者.
结论:

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...

Thoracic, aortic arch and abdominal aneurysms are significant vascular conditions that can present with various clinical manifestations and lead to serious complications. Understanding these manifestations and the appropriate diagnostic studies is essential for effective management and treatment.Thoracic Aortic AneurysmsThoracic aortic aneurysms often remain asymptomatic until they reach a size that impinges on adjacent structures. They typically cause deep, diffuse chest pain that radiates to...

Diagnosing acute coronary syndrome or ACS begins with a thorough patient history. Notable symptoms include central, crushing chest pain radiating to the left arm, neck, jaw, or back, along with shortness of breath, sweating (diaphoresis), nausea, vomiting, dizziness, and palpitations.It is crucial to note any history of cardiac illnesses and assess risk factors, including age, gender, smoking, hypertension, diabetes, hyperlipidemia, and a sedentary lifestyle.During physical examination, vital...
