BACKGROUND Several treatment options are available for pulmonary vascular disease, and more patients are considered for right heart catheterization. The aims of this study were to evaluate the diagnostic ability of echocardiography to detect pulmonary hypertension and increased pulmonary vascular resistance (PVR). METHODS This retrospective study comprised 118 patients investigated within 48 ...

AIM To evaluate the efficacy of angiotensin converting enzyme inhibitors Enalapril, Fosonopril and Moexipril on mean and systolic pulmonary artery pressure. MATERIAL AND METHODS The study included Ill patients with chronic obstructive bronchopneumopathies associated with arterial hypertension and mild to moderate heart failure (NYHA I-II class). The patients were examined at baseline and afte...

s of papers 31 133 Venous Blood Pressure in Broilers During Acute Inhalation of 5% Carbon Dioxide, and During Unilateral Pulmonary Artery Occlusion. R. F. Wideman, Jr.*, P. Maynard, and W. G. Bottje, . We evaluated the hypothesis that venous congestion (increased venous volume) and venous hypertension (increased venous pressure), may arise when the right ventricle must elevate the pulmonary art...

To investigate the relationships between local platelet activation in pulmonary vessels and pulmonary artery pressure circulating platelet aggregates and plasma beta-thromboglobulin (beta-TG) levels were evaluated in peripheral venous blood and blood from different sites of pulmonary circulation (right ventricle, pulmonary artery and arteriolo-capillary bed) in 29 patients with COPD. Fifteen ha...

BACKGROUND The aim of this study was to investigate the feasibility of main pulmonary artery diameter quantification by thoracic computerized tomography (CT) in the diagnosis of pulmonary hypertension seconder to biomass smoke exposure. MATERIAL AND METHODS One hundred and four women subjects with biomass smoke exposure and 20 healthy women subjects were enrolled in the prospective study. The...

To determine the effects of chronic intrauterine pulmonary hypertension on the perinatal pulmonary circulation, we induced chronic elevations of pulmonary artery pressure in 24 late-gestation fetal lambs by maintaining partial compression of the ductus arteriosus with an inflatable vascular occluder. Pulmonary artery pressure was increased from 44 +/- 1 to 62 +/- 3 mmHg for 3-14 d. Although lef...

background pulmonary artery hypertension is the presentation of various types of cardiovascular and systematic diseases. there are different kinds of noninvasive methods to determine right ventricular function, pulmonary artery pressure, and effect of pulmonary hypertension on right ventricular function. these methods include the tissue doppler imaging (tdi) of the tricuspid annulus and the lon...

AIMS The study sought to assess the effect of percutaneous pulmonary artery denervation (PADN) on balloon-occlusion-induced acute pulmonary arterial hypertension (PAH) in vivo. The PADN is a minimally invasive and endovascular catheter-based interventional therapy using radiofrequency ablation to abolish the pulmonary arterial baroreceptors to pressure response. METHODS AND RESULTS To examine...

Pulmonary vein stenosis (PVS) post radiofrequency ablation for chronic atrial fibrillation poses a diagnostic challenge for the clinician. PVS presents with nonspecific symptoms, signs and radiographic features, and may be associated with significant pulmonary vascular involvement. Interestingly, others have described variation of the pulmonary artery wedge pressure between sites of the lung as...
