CTEPH remains underdiagnosed and can be difficult to differentiate on routine CTPA from acute PE and from patients without pulmonary thromboembolism. We developed and evaluated a fully automated CTPA-based machine learning algorithm combining vascular blood volume metrics with clot and periclot imaging features.
Acute-on-chronic thromboembolic pulmonary hypertension (acute-on-CTEPH) is associated with rapid clinical deterioration, yet the role of invasive intervention in the acute phase remains poorly defined.
Pulmonary arterial hypertension (PAH) is a life-limiting disease with psychosocial burden, although US population-level estimates of incident mental health (MH) disorders remain limited.
Contrast-enhanced micro-computed tomography (micro-CT) provides high-resolution, three-dimensional visualization of small vascular structures in situ, enabling detailed analysis of morphological changes in the perinatal vasculature.
Pulmonary arterial hypertension (PAH) in Latin America and the Caribbean (LAC) remains poorly characterized, with limited regional data on clinical presentation, hemodynamics, treatment patterns, and outcomes.
Sotatercept, an activin signaling inhibitor for pulmonary arterial hypertension (PAH), has demonstrated significant improvements in clinical outcomes though its off-target effects are still an area for discovery. Anecdotal increases in total body weight not attributable to fluid retention have been observed.
In patients with pulmonary arterial hypertension, pressure-based right ventricular ejection fraction (RVEF) estimated from routine right heart catheterisation correlated with RVEF from magnetic resonance imaging.
Pulmonary hypertension (PH) is a multifaceted disorder characterized by the crucial involvement of activated hypoxia-inducible factors (HIFs). Recent investigations have unveiled HIFs' ability to orchestrate a wide array of signaling cascades, encompassing voltage-gated potassium channels, non-selective cation channels (NSCCs), Ca2+/PKC/MAPKs, PI3K/Akt, RhoA/ROCK, Notch, VEGF, and miRNA pathways.
Pulmonary hypertension caused by fibrosing mediastinitis (PH-FM) is a high-risk condition with limited validated tools for prognostic assessment. Although diffusing capacity of the lung for carbon monoxide (DLCO) predicts outcomes in several cardiopulmonary diseases, its prognostic value in PH-FM remains unclear.
Pulmonary hypertension (PH) is a frequent complication of fibrotic interstitial lung diseases (ILDs), but its detection remains challenging due to overlapping clinical features. We aimed to evaluate the discriminatory power of physiological and exercise-based markers that differentiate right heart catheterization (RHC)—confirmed PH from low-probability ILD cases.
