This research aims to investigate the impact of Didang decoction (DD) on the formation of neutrophil extracellular traps (NETs) and cancer-associated thrombosis in lung cancer. BALB/c nude mice were used to establish xenograft models for inducing deep vein thrombosis. Tumor growth and thrombus length were assessed.

Endothelial dysfunction is an underlying mechanism for the development of pulmonary arterial hypertension (PAH). Vascular endothelial growth factor (VEGF) and stromal cell-derived factor-1α (SDF) may help repair the dysfunctional endothelium and provide treatment for PAH.

Right ventricle (RV)-to-pulmonary artery (PA) coupling measured by the ratio of echocardiography-derived tricuspid annular plane systolic excursion (TAPSE) and pulmonary artery systolic pressure (PASP) is a meaningful prognostic marker in pulmonary hypertension (PH).

The PERFECT study, a randomized, controlled, double-blind study of inhaled treprostinil in patients with COPD and associated pulmonary hypertension (PH-COPD) was a negative trial that was terminated early. The reason(s) for the negative outcome remains uncertain.

Part of the Hypoxia in pulmonary vascular research – altitude and beyond webinar series

In this Community Call, we discussed:

• Digital spatial profiling identifies distinct molecular signatures of vascular lesions in PAH
• Phosphodiesterase-5 inhibitor treatment is associated with improved survival in pulmonary hypertension associated with COPD in the PVRI GoDeep meta-registry

Exercise training is recommended for pulmonary hypertension (PH). Post hoc analysis of the PH and Home-Based (PHAHB) trial stratified patients into two groups based on median diffusing capacity of the lungs for carbon monoxide (DLCO).

We present the case of an 18-year-old woman with a 5-day history of thoracic pain and dyspnea following physical exertion, along with swelling of her right calf. Computertomography (CT) angiography confirmed a massive central pulmonary artery embolism (PE) of the left main branch.
