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 ...

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.

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 ...

Preoperative Aortic Calcification Volume Predicts Postoperative Complications in Nonpancreatic Cancer Patients Undergoing Pancreaticoduodenectomy

open access: yesAnnals of Gastroenterological Surgery, EarlyView.
ABSTRACT Background/Objectives Postoperative complications following pancreaticoduodenectomy (PD) remain high, particularly in patients with soft pancreatic texture. Abdominal aortic calcification volume (AACV), a surrogate marker of systemic arteriosclerosis, has been associated with increased surgical risk in lower gastrointestinal procedures ...

The role of endothelin-1 in pulmonary arterial hypertension. [PDF]

open access: yes, 2014
Pulmonary arterial hypertension (PAH) is a rare but debilitating disease, which if left untreated rapidly progresses to right ventricular failure and eventually death. In the quest to understand the pathogenesis of this disease differences in the profile,

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.

Nationwide Real‐World Modeling of Surgical Outcomes in Elderly Patients: Incorporating Geriatric‐Specific Risk Factors Into Prediction of Mortality and Morbidity

open access: yesAnnals of Gastroenterological Surgery, EarlyView.
A reliable and effective risk prediction model for mortality and morbidity in elderly patients undergoing gastroenterological surgeries was developed and validated. Geriatric‐specific risk factors, including the newly added variables in the NCD registry, along with age, were identified as significant contributors to the model. ABSTRACT Aim As the aging

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.
