Right ventricular diastolic impairment in patients with pulmonary arterial hypertension.
BACKGROUND The role of right ventricular (RV) diastolic stiffness in pulmonary arterial hypertension (PAH) is not well established. Therefore, we investigated the presence and possible underlying mechanisms of RV diastolic stiffness in PAH patients. METHODS AND RESULTS Single-beat RV pressure-volume analyses were performed in 21 PAH patients and 7 control subjects to study RV diastolic stiffn...
متن کاملEvaluation of Advanced Echocardiographic Parameters of Right Ventricular in Patients with Pulmonary Hypertension
Background and Objective: Pulmonary hypertension is an increase in blood pressure of the pulmonary artery which leads to right ventricular dysfunction. Therefore, the present study aimed to compare echocardiographic parameters in the study of right ventricular failure in patients with pulmonary hypertension. Materials and Methods: In the present descriptive cross-sectional study, data were col...
متن کاملEchocardiographic evaluation of left-ventricular diastolic function in patients with chronic pulmonary hypertension.
Different patterns of left-ventricular (LV) diastolic dysfunction were reported in patients with pulmonary hypertension (PHT). There are no data regarding the relationship between the severity of PHT and LV diastolic dysfunction. In order to determine the severity of PHT at which LV diastolic dysfunction occurs and to identify its pattern, we studied by Doppler echocardiography 120 patients wit...
متن کاملThe prevalence of right to left shunt in chronic obstructive pulmonary disease patients with increased pulmonary hypertension
Background: One of the important etiologies for cryptogenic stroke is paradoxical embolization secondary to Patent Foramen Ovale (PFO). Foramen ovale can secondarily reopen due to Pulmonary Arterial Hypertension (PAH) which is common among the older age. PAH is known as a frequent and life threatening complication of COPD. The aim of this study was to determine the prevalence of PFO between COP...
متن کاملEchocardiographic Evaluation of Right Ventricular Function in Patients with Chronic Pre-Capillary Pulmonary Hypertension
In chronic pre-capillary pulmonary hypertension the right ventricle undergoes extensive remodeling (an increase in volume, a change in shape and an increase in wall thickness) that allows it to maintain an adequate right ventricular (RV) output at rest despite the high afterload. The anatomic characteristics of the pressure overloaded right ventricle have been described using various imaging te...
