Right heart size and function significantly correlate in patients with pulmonary arterial hypertension – a cross-sectional study

Respiratory Research, 2018
Background The objective of this study was to assess, whether right atrial (RA) and ventricular (RV) size is related to RV pump function at rest and during exercise in patients with pulmonary arterial hypertension (PAH).

Non-Invasive Pulmonary Artery Wave Intensity Analysis in Pulmonary Hypertension. [PDF]

, 2015
Pulmonary wave reflections are a potential hemodynamic biomarker for pulmonary hypertension (PH) and can be analyzed using wave intensity analysis (WIA). In this study we used pulmonary vessel area and flow obtained using cardiac magnetic resonance (CMR)

Exploratory analysis of the neutrophil to lymphocyte ratio in patients with pulmonary arterial hypertension

BMC Pulmonary Medicine, 2017
Background Chronic inflammation emerges as a feature of the pathogenesis of pulmonary arterial hypertension (PAH) in experimental models. Alterations of circulating cell subsets have been observed in patients with PAH.

Pulmonary Hypertension [PDF]

Pulmonary Medicine, 2012
Pulmonary hypertension (PH), defined as elevated pulmonary artery pressure, is common in the general population and associated with increased mortality. Accordingly, physicians commonly encounter patients with dyspnea, exercise intolerance, and/or right heart failure who have elevated pulmonary artery systolic pressure (PASP) on echocardiography ...

Impact of targeted pulmonary arterial hypertension therapies in severe pulmonary hypertension in chronic lung diseases

ERJ Open Research, 2023
Research questions Patients with severe pulmonary hypertension associated with chronic lung disease have a poor prognosis. Targeted pulmonary arterial hypertension therapies might improve exercise capacity and outcome, but there are no guidelines on ...

Metabolism of asymmetric dimethylarginines is regulated in the lung developmentally and with pulmonary hypertension induced by hypobaric hypoxia [PDF]

, 2003
Background— Nitric oxide (NO) plays an important part in lowering pulmonary vascular resistance after birth, and in persistent pulmonary hypertension of the newborn (PPHN), NO-mediated dilation is dysfunctional.

Pulmonary hypertension [PDF]

Current Problems in Cardiology, 2004
Pulmonary hypertension, in its simplest sense, is elevation of the pulmonary artery pressure above normal. A multitude of diseases may increase the pulmonary artery pressure and result in right ventricular dysfunction. The treatments of pulmonary hypertension are as varied as its causes.
