Ambulatory Hemodynamic Monitoring in the Management of Pulmonary Arterial Hypertension
Raymond L. Benza, MD Cardiovascular Institute Allegheny General Hospital Pittsburgh, PA Background: Pulmonary arterial hypertension (PAH) is characterized by pulmonary vascular remodeling, rise in pulmonary arterial pressures, and if left untreated, right heart failure. Invasive hemodynamic assessment with right heart catheterization (RHC) has been the gold standard for the diagnosis and serial...
متن کاملAmbulatory Hemodynamic Monitoring of Pulmonary Hypertension
Elevated pulmonary artery pressure, typically called “pulmonary hypertension (PH)”, may occur owing to several pathophysiological conditions. The World Health Organization (WHO) proposed 5 classifications of PH, primarily based on causality, in order to guide research and provide a framework for therapeutic intervention. The WHO group II PH is most common and characterized by a mean pulmonary a...
متن کاملTHE EFFECTS OF CAPTOPRIL ON PULMONARY AND SYS TEMIC ARTERIAL PRESSURES IN HIGHALTITUDE PULMONARY HYPERTENSION
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 measurem...
متن کاملThe Importance of Electrocardiography in Pediatric Patients with Pulmonary Arterial Hypertension in Follow- up
Background: Right Ventricular (RV) hypertrophy is an adaptive response to chronic RV pressure overload in patients with pulmonary hypertension. We investigated the relationships between RV hypertrophy indicators, including electrocardiography, the percentage oxygen saturation (SaO2%), body mass index (BMI), and blood uric acid levels in patients with...
متن کاملCurrent perspectives modern hemodynamic evaluation of the pulmonary circulation. Application to pulmonary arterial hypertension and embolic pulmonary hypertension.
The hemodynamic evaluation of the pulmonary circulation normally includes the measurements of mean pulmonary artery pressure and a calculation of pulmonary vascular resistance (PVR). The definition of PVR can be improved by the measurements of pulmonary vascular pressures at several levels of flow to derive a pressure-flow line, and the site of PVR can be identified by the analysis of pulmonary...
