概括
N-终端亲脑尿性 (NT-proBNP) 可以帮助识别低风险急性肺栓塞 (APE) 患者,适合早期出院. 较高的NT-proBNP水平表明临床终点的风险,表明更密切的监测.
科学领域:
- 心脏病学 心脏病学
- 肺部病理学 肺部病理学
- 生物标志物研究 生物标志物研究
背景情况:
- 急性肺栓塞 (APE) 患者异质,有些人有资格获得早期出院和门诊护理.
- 风险分层对于管理APE至关重要,识别可以安全过渡到门诊管理的患者.
- 简化肺栓塞严重性指数 (sPESI) 用于评估低风险的APE患者.
研究的目的:
- 在低风险APE患者 (sPESI = 0) 中评估N-终端前脑性尿性 (NT-proBNP) 血水平的有用性.
- 确定NT-proBNP是否可以预测该患者组的临床终点.
- 为了确定一个潜在的NT-proBNP切线,以便获得门诊治疗的资格.
主要方法:
- 一项前性研究,包括1151名血压正常患者,至少有细分APE.
- 最终的分析集中在348名患者身上,他们的sPESI为0分.
- 在入院后24小时内采集NT-proBNP的血液样本;跟踪临床终点 (与APE相关的死亡率或救援血栓溶解).
主要成果:
- 三名患者经历了临床终点,显示了明显更高的NT-proBNP水平 (中位数为2,930 pg/mL),相比那些有良好的结果 (中位数为164 pg/mL;p=0.01).
- 接收器操作特征 (ROC) 分析表明NT-proBNP的预测值很高 (AUC = 0.918,p=0.013).
- 确定NT-proBNP≥1,641 pg/mL的截止值用于预测临床终点.
结论:
- 在低风险APE患者中 (sPESI=0),NT-proBNP水平≥1,641 pg/mL可能表明需要更密切的监测.
- 低于这个值的NT-proBNP水平的患者可能是门诊治疗的候选人.
- 建议在更大的前性研究中进行进一步验证,以确认这些发现.

Blood Studies for Cardiovascular System II: CRP, Hcy, and Cardiac Natriuretic Peptide Markers
68
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...

Treatment for Pulmonary Arterial Hypertension: Endothelin Receptor Antagonists
142
Endothelins (ETs) are potent vasoactive peptides critical in the human body's various physiological and pathological processes. One of the most promising therapeutic strategies for treating pulmonary arterial hypertension (PAH) involves counteracting the effects of these endothelins using a class of drugs known as endothelin receptor antagonists.
ETs are synthesized through a complex sequence of enzymatic steps, primarily involving an enzyme referred to as endothelin-converting enzyme...

Radiological Investigation III: Pulmonary Angiogram and PET Scan
88
Radiological investigations are paramount in the diagnosis and management of various pulmonary diseases. Two essential investigations are the Pulmonary Angiogram and the Positron Emission Tomography (PET) Scan.
Pulmonary Angiogram
A Pulmonary Angiogram is an invasive procedure involving injecting a contrast medium through a catheter threaded into the pulmonary artery or the right side of the heart to visualize the pulmonary vasculature. Computed Tomography (CT) scans have mainly replaced this...
