Diabetes induces advanced glycation end products (AGEs) that per se are not only a major cause of oxidative stress but also reduce the plasticity of connective tissue by pathological collagen cross-linking. We describe a case of severe pulmonary hypertension manifesting as a major diabetic complication. Impaired pulmonary arteriolar plasticity attributed to pentosidine, together with increased circulation volume by hyperosmotic pressure and reduction in myocardial compliance by multiple patchy fibrosis, may contribute to the clinical manifestation of severe pulmonary hypertension.

A growing body of evidence suggest that the stem cell antigen-1 expressing (Sca-1) cells in the heart may be the cardiac endothelial stem/progenitor cells. Their endothelial cell (EC) functions, and their role in RV physiology and pathophysiology of right heart failure (RHF) remains poorly defined. This study investigated EC characteristics of rat cardiac Sca-1 cells, assessed spatial distribution and studied changes in Sca1 cells during RV remodelling in monocrotaline (MCT) model of pulmonary hypertension and RV remodeling.

Advances in chronic thromboembolic pulmonary hypertension (CTEPH) treatment have improved prognosis, shifting focus towards symptom management. This study aimed to identify factors influencing the World Health Organization functional class (WHO-FC) in CTEPH patients. The CTEPH AC registry is a prospective, multicenter database from 35 Japanese institutions, analyzing data from August 2018 to July 2023.

Purpose: Pulmonary hypertension (PH) is associated with morbidity and mortality in patients with interstitial lung disease (ILD). Several prediction models have been proposed to predict PH in ILD patients. We sought to discern how previously described prediction models perform in predicting PH in patients with ILD.

Background: Pulmonary hypertension caused by extrinsic pulmonary vascular compression secondary to mediastinal neuroendocrine tumours is a very rare condition, posing a diagnostic challenge. There is no clear consensus regarding the best treatment strategy due to the lack of clinical data, leading to poor prognoses for these patients.
Case Summary: We present the case of a 38-year-old man hospitalized with signs of pulmonary hypertension and acute heart failure.

Background: Pulmonary arterial hypertension (PAH) poses a significant health challenge globally, with China experiencing a notable increase in its burden. Understanding the trends and factors contributing to PAH is crucial for developing effective public health strategies.
Methods: This study utilized data from the Global Burden of Disease (GBD) 2021 database to estimate the burden of PAH in China and worldwide from 1990 to 2021.
