Echocardiographic Ratio Shows Pre- and Post-Capillary Pulmonary Hypertension
The novel echocardiographic pulmonary to left atrial global strain ratio distinguishes pre-capillary from post-capillary pulmonary hypertension.
Pulmonary Hypertension
Childhood Pulmonary Hypertension Subtypes, Survival Vary by Race/Ethnicity
There is significant variation by race and ethnicity in the prevalence of childhood pulmonary hypertension subtypes and survival outcomes.
HFpEF With Severe Pulmonary Hypertension Linked to Increased Mortality
Patients with heart failure, severe pulmonary hypertension, and a preserved ejection fraction of ≥50% had a worse prognosis when compared with other patients with heart failure and severe pulmonary hypertension.
Domiciliary Oxygen Increases Exercise Capacity in Pulmonary Hypertension
Patients with pulmonary arterial or distal chronic thromboembolic pulmonary hypertension were able to increase 6-minute walk distance and improve physical status on domiciliary oxygen therapy.
BET Inhibitor Reverses Vascular Remodeling in Pulmonary Arterial Hypertension
At a clinically relevant dose, RVX208 improved hemodynamics and reversed pulmonary vascular remodeling in certain pulmonary arterial hypertension models in rats.
Right Ventricular Fibrosis Linked to PA Stiffness in Pulmonary Hypertension
Investigators sought to determine whether measurements of right ventricle extracellular volume are associated with noninvasive measures of pulmonary artery stiffness.
Pulmonary Vascular Distensibility: An Early Marker of Pulmonary Vascular Disease
Decreased pulmonary vascular distensibility was associated with right ventricular pulmonary arterial uncoupling in patients with unexplained exercise intolerance with normal resting echocardiography results.
PH Survival in Chronic Lung Disease Predicted by Echocardiographic Parameters
The ratio of tricuspid annular plane systolic excursion to systolic pulmonary artery pressure is a simple echocardiographic parameter that can predict survival in pulmonary hypertension due to lung diseases.
CMR Imaging Similarities Between Pulmonary Hypertension Subtypes
Patients with either pulmonary arterial hypertension or chronic thromboembolic pulmonary hypertension who underwent cardiac magnetic resonance imaging showed similar right ventricular and pulmonary artery features.
Lower RVSP Threshold Linked to Mortality Risk in Pulmonary Hypertension
All-cause and cardiovascular mortality rates in patients with pulmonary hypertension are markedly elevated above an echocardiographical estimated right ventricular systolic pressure of >30 mm Hg.
