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 ...

Pulmonary Hypertension [PDF]

open access: yesAmerican Journal of Respiratory and Critical Care Medicine, 2015
Pulmonary hypertension is said to occur when the mean pulmonary arterial pressure exceeds 25 mmHg at rest or 30 mmHg during exercise. There are many causes but the term Pulmonary arterial hypertension (PAH) is used to describe a rare group of illnesses that share histopathological similarities in the small muscularised pulmonary arterioles leading to ...

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

open access: yesRespiratory 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).

Pulmonary Hypertension [PDF]

open access: yesPulmonary 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 ...

Chronic thromboembolic pulmonary hypertension following long-term peripherally inserted central venous catheter use

open access: yesPulmonary Circulation, 2019
A 36-year-old woman presented with recurrent pulmonary emboli (PE) despite oral anticoagulation. She was a type I diabetic with severe gastroparesis requiring insertion of multiple long-term peripherally inserted central catheters (PICC) over a 10-year ...

Pulmonary hypertension [PDF]

open access: yesCurrent 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.
