a2-year-old cachectic cross-breed gelding was admitted toveterinary teaching hospital of university of tehran followingthe onset of a marked respiratory distress, coughing and ventraledema. clinical examinations indicated harsh respiratory andexpiratory sounds as well as jugular vein distention. therespiratory and heart rates were 35/min and 60 bpm, respectively.agrade iii/iv pansystolic murmur...

Right heart catheterization remains necessary for the diagnosis of pulmonary hypertension and, therefore, prognostic evaluation patients with chronic failure. The non-invaSive Assessment Pulmonary vasculoPathy in Heart failure (SAPPHIRE) study was designed to assess feasibility and relevance a non-invasive artery vasculature hypertension. Patients will undergo right catheterization, cardiac res...

the purpose of this investigation was to assess the effect of captopril on both systemic (p.a) and pulmonary arterial pressures (ppa) in patients with high-altitude pulmonary hypertension (haph). seventeen patients (mean age 44±6.8 years) with haph and mild to moderate systemic arterial hypertension were included in the study. all patients underwent right heart catheterization with measurements...

AIM To characterize the buffering function of the pulmonary artery in vivo and to determine the role of vascular smooth muscle (VSM) activation in vessel wall elasticity. MATERIAL AND METHOD Pulmonary artery pressure and diameter were measured in 9 anesthetized sheep. Pulmonary artery hypertension was induced by mechanical occlusion of the pulmonary artery and by phenylephrine infusion (5 mic...

conclusions our case highlights the fact that the tip of the pulmonary artery catheter can easily advance into a peripheral branch of the pulmonary artery and cause pulmonary venous blood to be sampled instead of pulmonary arterial blood. a variety of monitoring techniques are needed to confirm accurate catheter placement. background pressure and waveform at the catheter tip are continuously mo...

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...

Pulmonary hypertension is a hemodynamic and pathophysiological condition defined as an increase in mean pulmonary pressure more than or equal to 25 mm Hg. Risk stratification and prognostic evaluation in patients with pulmonary hypertension are complex and require multiple investigations. There is a lack of consensus on factors that predict mortality and prognosis in patients with pulmonary art...

The aim of the present study was to determine whether there is a relationship between coronary artery disease and pulmonary hypertension and whether pulmonary hypertension is an additional risk factor for the presence and extent of coronary artery disease in patients with chronic obstructive pulmonary disease. Patients diagnosed with chronic obstructive pulmonary disease and pulmonary hypertens...
