The impact of gas transfer on responses to exercise training in patients with pulmonary hypertension

Our prospective study investigates the 3-year trajectory of disease-specific quality of life (QoL) using the PEmb-QoL questionnaire, functional performance via 6-min walk tests, and the 5-year survival following acute pulmonary embolism (PE) and explores their association with patient demographics and clinical characteristics. We highlight that PE-specific QoL improves over time despite no significant changes in cardiopulmonary performance.

Current methods for quantifying perfusion from computed tomography pulmonary angiography (CTPA) often rely on semi-quantitative scoring systems and requires an experienced evaluator. Few studies report on absolute quantitative variables derived from the images, and the methods are varied with mixed results.

A 56-year-old male patient was admitted to our hospital with respiratory distress persisting for half a month as the chief complaint. The patient developed dyspnea following a heated argument...

Wave intensity analysis (WIA) uses simultaneous changes in pressure and flow velocity to determine wave energy, type, and timing of traveling waves in the circulation. In this study, we characterized wave propagation in the pulmonary artery in patients with...
