Glutaminolysis: A Driver of Vascular and Cardiac Remodeling in Pulmonary Arterial Hypertension
Frontiers in Cardiovascular Medicine, 2021 Pulmonary arterial hypertension (PAH) is a decimating ailment described by chronic precapillary pulmonary hypertension, an elevated mean pulmonary arterial pressure with a normal pulmonary capillary wedge pressure, and a raised pulmonary vascular ...

Right ventricular outflow tract velocity time integral-to-pulmonary artery systolic pressure ratio: a non-invasive metric of pulmonary arterial compliance differs across the spectrum of pulmonary hypertension. [PDF]
, 2019 Pulmonary arterial compliance (PAC), invasively assessed by the ratio of stroke volume to pulmonary arterial (PA) pulse pressure, is a sensitive marker of right ventricular (RV)-PA coupling that differs across the spectrum of pulmonary hypertension (PH ...

The choice of the intravenous fluid influences the tolerance of acute normovolemic anemia in anesthetized domestic pigs [PDF]
, 2012 The correction of hypovolemia with acellular fluids results in acute normovolemic anemia. Whether the choice of the infusion fluid has an impact on the maintenance of oxygen (O2) supply during acute normovolemic anemia has not been investigated so far ...

The Relationship of Pulmonary Venous Wedge to Pulmonary Arterial Pressures [PDF]
Circulation, 1971 A comparison of pressure levels and pressure-time relationships in pulmonary artery pressure (PAP) and pulmonary venous wedge pressure (PVWP) tracings was made from cardiac catheterization records of 60 patients, aged 1 day to 16 years. In 50 patients with normal or low PAP's there was close correlation between systolic, diastolic, and mean pressures ...

Goal-directed therapy in intraoperative fluid and hemodynamic management. [PDF]
, 2013 Intraoperative fluid management is pivotal to the outcome and success of surgery, especially in high-risk procedures. Empirical formula and invasive static monitoring have been traditionally used to guide intraoperative fluid management and assess volume
