Hepatic venous pressure gradient (HVPG) measurement has been widely used to estimate portal pressure gradient (PPG) and detect portal hypertension. However, some clinical studies have found poor correlation between HVPG and PPG, which may lead to the misdiagnosis of portal hypertension. In this ...
通过全局敏感度分析,证实了HVPG估测门脉压力梯度(PPG)的精度主要受到肝血窦前门静脉阻抗以及门脉上游内脏血管阻抗的影响。利用该模型进一步模拟在人群中进行HVPG测量的结果,得到了以PPG为标准时HVPG误诊与漏诊的分布。通过分析各参数之间的内在联系可以看...

Instead of reporting raw data from the PPG sensor, the Omnicept SDK aggregates PPG data, reporting only heartrate and pulse rate variability, but not the beat-by-beat cardiac trace. We want to protect end users from sharing sensitive information about their health whenever possible and this is...

目前,在肝硬化相关门脉高压症的诊疗中,广泛应用肝静脉压力梯度(HVPG)来间接估计门静脉压力梯度(PPG)。尽管HVPG的临床实用价值已被证实,然而,对肝硬化发病和进展过程中所涉及的因素如何影响HVPG和PPG的相关性所知甚少。我国上海交通大学船舶海洋与建筑工程学院Wang等近日完成的一项研究表明,为了更好的在临床实践中理解和...
Portosystemic pressure gradient (PPG: portal venous pressure, IVC/RA) should be calculated prior to and after TIPS implantation. (A1) 46. PPG should be aimed at <12 mm Hg and >8 mm (at minimum a decrease of >50% in patients with high PPG > 30 mm Hg prior to TIPS shou...
On March 26, 2025, PPG announced the startup of a waterborne automotive coatings manufacturing plant in Samut Prakan, Thailand. The state-of-the-art plant, with a 2,000-ton annual capacity, features an automated spray application center. The opening was marked by a special event on March ...
