概括

在儿童肺动脉高血压 (PAH) 中,肺血管损伤与生存有关. 较低的PVC表明PAH儿童的治疗结果和生存率更好.

科学领域:

心血管研究
儿童肺病学
医学中的计算建模

背景情况:

儿童肺动脉高血压 (PAH) 涉及显著的无症状肺血管损失.
在符合临床PAH标准之前,多达70%的肺血管可以消失.
一个计算模型可以估计肺血管损害 (PVC).

研究的目的:

评估估计的PVC与儿科PAH的血液动力学变量之间的关联.
确定儿童PAH中PVC与无移植存活率之间的关系.
评估PVC与儿童PAH其他临床结果的相关性.

主要方法:

儿科PAH患者的回顾性和前性队列数据 (1999-2022年).
与计算模型估计的PVC一起分析了心脏导管和临床数据.
使用卡普兰 - 梅尔分析和Cox比例危险回归来评估生存率和死亡率.

主要成果:

较低的PVC与更高的无移植存活率 (p < 0. 001) 有关.
超过80%的PVC与10年生存率为54%相关,而PVC<80%的100% (p<0.001).
PVC是死亡率的显著预测因素 (HR1.44, p = 0.008) 并与更好的临床结果相关.

结论:

估计PVC是一种新的血液动力学变量,用于量化儿科PAH的血管损失.
在儿童的PAH中,PVC与无移植生存率和临床结果有显著的关联.
在早期检测血管损失和监测治疗反应方面,PVC是潜在的辅助工具.

Pulmonary Hypertension: Classification and Pathogenesis

Pulmonary Hypertension: Classification and Pathogenesis

Pulmonary hypertension (PH) is a severe health condition in which the mean pulmonary arterial pressure increases to 25 mmHg or more, even when the body is at rest. This high pressure in the blood vessels that transport blood from the heart to the lungs can cause various symptoms, including shortness of breath, can lead to right heart failure, and significantly affect the overall quality of life.
There are various classifications for PH, each relating to different underlying causes and also...

Physiological Pharmacokinetic Models: Blood Flow-Limited Versus Diffusion-Limited Models

Physiological Pharmacokinetic Models: Blood Flow-Limited Versus Diffusion-Limited Models

Physiological pharmacokinetic models, often called flow-limited or perfusion models, typically assume a swift drug distribution between tissue and venous blood, creating a rapid drug equilibrium. This premise is based on the idea that drug diffusion is extremely fast, and the cell membrane presents no barrier to drug permeation. In this scenario, where no drug binding occurs, the drug concentration in the tissue equals that of the venous blood leaving the tissue. This greatly simplifies the...
