Altered gut microbiota and its association with inflammation in patients with chronic thromboembolic pulmonary hypertension: a single-center observational study in Japan

open access: yesBMC Pulmonary Medicine, 2022
Background The pathogenesis of chronic thromboembolic pulmonary hypertension (CTEPH) is considered to be associated with chronic inflammation; however, the underlying mechanism remains unclear. Recently, altered gut microbiota were found in patients with

Multi‐angle fluoroscopic lung perfusion imaging using x‐ray pulsatility index: A pilot study in healthy subjects

open access: yesMedical Physics, Volume 53, Issue 9, September 2026.
Abstract Background X‐ray pulsatility index (XPI) quantifies cardiac‐synchronous attenuation changes as a surrogate for regional lung perfusion, but current implementations are limited by projectional overlap and the lack of reference values in healthy individuals. Purpose To characterize regional XPI patterns and establish preliminary reference values

Cardiopulmonary exercise testing and pulmonary function testing for predicting the severity of CTEPH

open access: yesBMC Pulmonary Medicine, 2021
Background Cardiopulmonary exercise testing (CPET) and pulmonary function testing (PFT) are noninvasive methods to evaluate the respiratory and circulatory systems. This research aims to evaluate and monitor chronic thromboembolic pulmonary hypertension (

Occlusion pressure analysis role in partitioning of pulmonary vascular resistance in CTEPH.

open access: yes, 2012
Flow-directed pulmonary artery occlusion is posited to enable partitioning of vascular resistance into small and large vessels. As such it may have a role in assessment for pulmonary endarterectomy.To test if the occlusion technique distinguished small ...

How Do Sleep Difficulties Interact With Anxiety, Depression and Health‐Related Quality of Life in Pulmonary Hypertension?

open access: yesThe Clinical Respiratory Journal, Volume 20, Issue 8, August 2026.
Our findings support that of others suggesting that most adults with pulmonary hypertension report difficulties with sleep, highlighting the importance of routine screening. Where sleep difficulties are identified, screening for co‐occurring depression may also be required given the strong association between the two.

The Evolving Landscape of Pulmonary Hypertension Treatment: From Vasodilation to Disease Modification

open access: yesClinical and Translational Science, Volume 19, Issue 8, August 2026.
ABSTRACT Pulmonary hypertension (PH) is a complex disorder associated with significant morbidity and mortality. PH is characterized by an elevated pulmonary vascular load, leading to right ventricular dysfunction and remodeling, with right heart failure and premature death if left untreated.

An epidemiological analysis of the burden of chronic thromboembolic pulmonary hypertension in the USA, Europe and Japan

open access: yesEuropean Respiratory Review, 2017
Epidemiological data for chronic thromboembolic pulmonary hypertension (CTEPH) are limited and there are conflicting reports regarding its pathogenesis. A literature review was conducted to identify CTEPH epidemiological data up to June 2014.
