Pediatric Pulmonary Hypertension

open access: yesJournal of the American College of Cardiology, 2013
Pulmonary hypertension (PH) is a rare disease in newborns, infants, and children that is associated with significant morbidity and mortality. In the majority of pediatric patients, PH is idiopathic or associated with congenital heart disease and rarely is associated with other conditions such as connective tissue or thromboembolic disease.

PULMONARY ARTERIAL HYPERTENSION

open access: yesAnnals of Medicine, 2006
Pulmonary arterial hypertension is a disease of the small pulmonary arteries characterized by vascular narrowing and increased pulmonary vascular resistance, which eventually leads to right ventricular failure. Vasoconstriction, vascular proliferation, remodeling of the pulmonary vessels, and thrombosis are all contributing factors to the increased ...

Safety, tolerability, and efficacy of an in‐class combination therapy switch from bosentan plus sildenafil to ambrisentan plus tadalafil in children with pulmonary arterial hypertension

open access: yesPulmonary Circulation
The aim of this single‐centre retrospective observational study was to evaluate the safety, tolerability, and efficacy of an in‐class combination therapy switch from bosentan plus sildenafil to ambrisentan plus tadalafil in children with pulmonary ...

Low DLCO Can Provide Insights into Treatment Response in PAH Patients Irrespective of the Reason for Its Decrease

open access: yesLife
Group 1 of PAH patients encompasses patients with a diverse underlying etiological condition, having histological modifications that can affect gas exchange across the alveolar-capillary membrane, as reflected by decreased DLCO.

Exploring the Endothelin-1 pathway in chronic thromboembolic pulmonary hypertension microvasculopathy

open access: yesScientific Reports
Targeted vasopeptide therapies have significantly advanced the management of pulmonary arterial hypertension (PAH). However, due to insufficient preclinical evidence regarding the involvement of the endothelin-1 (ET-1) pathway in chronic thromboembolic ...

DDAH1 regulates apoptosis and angiogenesis in human fetal pulmonary microvascular endothelial cells

open access: yesPhysiological Reports, 2019
Nitric Oxide (NO) is an endogenous pulmonary vasodilator produced by endothelial NO synthase (eNOS). Asymmetric dimethyl L‐arginine (ADMA) is an endogenous inhibitor of eNOS activity.

Pulmonary Hypertension Caused by Pulmonary Venous Hypertension [PDF]

open access: yesPulmonary Circulation, 2014
The effect of pulmonary venous hypertension (PVH) on the pulmonary circulation is extraordinarily variable, ranging from no impact on pulmonary vascular resistance (PVR) to a marked increase. The reasons for this are unknown. Both acutely reversible pulmonary vasoconstriction and pathological remodeling (especially medial hypertrophy and intimal ...

Sarcopenia in Patients with Chronic Thromboembolic Pulmonary Hypertension

open access: yesJournal of Cardiovascular Development and Disease
Background: Sarcopenia, or loss of skeletal muscle mass, has been associated with poor outcomes (e.g., functional decline, increased mortality, and low quality of life), but its role in CTEPH remains unclear.

Pulmonary hypertension

open access: yesSwiss Medical Weekly, 2003
Pulmonary arterial hypertension (PAH) must be classified into primary pulmonary hypertension and PAH related to other diseases such as collagen vascular diseases, HIV infection or portal hypertension. PAH must also be differentiated from other entities, in particular pulmonary hypertension secondary to thromboembolic diseases, requiring specific ...
