Learning and research

Invasive exercise hemodynamics are used to diagnose heart failure with preserved ejection fraction (HFpEF), based on pulmonary artery wedge pressure (PAWP) or left atrial (LA) pressure elevations.

Pretreatment with targeted pulmonary arterial hypertension (PAH) therapy in adults with unrepaired atrial septal defects (ASDs) has been increasingly reported as a means to improve pulmonary hemodynamics and expand candidacy for defect closure.

A dry powder inhaler (DPI) formulation of treprostinil was FDA-approved in March 2022 for patients with pulmonary arterial hypertension or pulmonary hypertension associated with ILD (PH-ILD).

Pulmonary hypertension is a known complication of scimitar syndrome; however, its risk factors and outcomes are not well understood. This study aimed to assess the prevalence, clinical features, risk factors, and outcomes of pulmonary hypertension in patients with scimitar syndrome.

Physical activity (PA) estimated by a wearable sensor may reflect clinical status in pediatric pulmonary hypertension (PH). Prior studies used research-grade hip-anchored sensors or commercial wrist sensors with proprietary scoring algorithms. 

Pulmonary artery pressures (PAPs) often become abnormal during exercise in patients with systemic sclerosis (SSc). This study sought to determine whether exercise-induced pulmonary hypertension (EIPH) assessed by exercise stress echocardiography (ESE) would be associated with subsequent increases in resting PAPs in patients with SSc.

Part of the 'Hypoxia in pulmonary vascular research – altitude and beyond' webinar series by the High Altitude Task Force, who raise awareness and understanding of PH linked to high altitude and organise scientific conferences in regions affected by high altitudes.

Patients with pulmonary arterial hypertension (PAH) experience long delays in diagnosis; however, little is known about the time between diagnosis and initiation of guideline-recommended optimal treatment. Immediate therapy is imperative for optimizing patient outcomes, as much of the pulmonary vasculature has already deteriorated by the time of diagnosis. 

Accurate resting oxygen consumption (rVO2) quantification is critical for Fick-derived cardiac output calculations.
