概括
同时诊断心力衰竭 (HF) 和肺炎 (PN) 是一个挑战. 升高的N-终端前脑性尿素 (NT-proBNP) 和低的C-反应蛋白 (CRP) 水平可以帮助在CT扫描结果重叠的患者中区分HF和PN.
科学领域:
- 心脏病学 心脏病学
- 肺部病理学 肺部病理学
- 放射学 放射学是一门学科.
- 生物标志物 生物标志物
背景情况:
- 区分心力衰竭 (HF) 和肺炎 (PN) 很困难,因为这两种疾病都有重叠的症状和计算机断层扫描 (CT) 的成像发现.
- 对疑似HF和PN患者的临床特征和差异诊断的研究有限.
研究的目的:
- 研究生物标志物的临床特征和诊断实用性,以区分心力衰竭 (HF) 和肺炎 (PN) 在具有同时放射性发现的患者中.
- 在混合患者队列中确定诊断HF和PN的独立预测因子.
主要方法:
- 对220名呼吸障碍患者的回顾性分析,这些患者接受了胸部CT,并被诊断为肺炎和/或肺.
- 由专家分类为HF,PN或HF与PN (HFPN) 组.
- 收集临床数据,C-反应蛋白 (CRP),前素,N-终端脑前性尿素 (NT-proBNP) 和 I型热水平.
主要成果:
- 肺炎心力衰竭 (HFPN) 是最常见的诊断 (51.8%).
- 多变量分析确定NT-proBNP和CRP是HF诊断的独立生物标志物,NT-proBNP是PN的负预测因素.
- 一个CRP<91 mg/dL和NT-proBNP>2677 pg/mL的组合模型显示了最高的诊断值 (AUC 0.772) 来识别HF.
结论:
- 较高的NT-proBNP与较低的CRP水平相结合,在CT发现重叠的患者中,在区分HF和PN方面具有临床实用性.
- 在HF和HFPN组中,抗生素处方率很高,但与住院死亡率无关.
- 建议在多种不同人群中进一步验证.

Diagnosing Pulmonary EmbolismDiagnosing pulmonary embolism (PE) involves clinical assessment and advanced imaging tests. The preferred diagnostic tool is the spiral (helical) CT scan or CT angiography (CTA), which uses intravenous contrast media to visualize the pulmonary vasculature and identify emboli.A ventilation-perfusion (V/Q) scan is an alternative for patients unable to receive contrast media. This scan includes both perfusion and ventilation scanning. Perfusion scanning involves...

Pleural Effusion Overview
A pleural effusion is the abnormal collection of fluid between the parietal and visceral pleura layers of tissue that form the lining of the lungs and chest cavity. It can occur independently or due to surrounding parenchymal diseases, such as infection, malignancy, or inflammatory conditions.

Radiological Investigation II: MRI and Ventilation Perfusion Scan

Description
Magnetic Resonance Imaging (MRI) and Ventilation Perfusion Scans are two radiological investigations that offer detailed diagnostic images of the body, particularly lung structures.
MRI
MRI uses magnetic fields and radiofrequency signals to distinguish between normal and abnormal tissues. This technology provides a more detailed diagnostic image than CT scans, enabling it to characterize pulmonary nodules, stage bronchogenic carcinoma, and evaluate inflammatory activity in...
