Treatment with phosphodiesterase-5 (PDE5) inhibitors can improve blood flow parameters and exercise capacity in people with pulmonary hypertension (PH), according to a new analysis of clinical trial data. “The study found that the reduction in mean PAP [peripheral arterial pressure] was significantly greater in patients receiving PDE5 inhibitors,” the…
The U.S. Food and Drug Administration (FDA) has approved the third generation of Genosyl, Vero Biotech‘s tankless system for nitric oxide delivery, for use as part of care for newborns with pulmonary hypertension. “The continuous innovation of the GENOSYL Delivery System represents our commitment to neonatal intensive care…
The incidence of chronic thromboembolic pulmonary hypertension (CTEPH) after an episode of acute pulmonary embolism (PE) is likely underestimated, a study suggests. This occurs despite the high frequency of symptoms consistent with CTEPH, underscoring that an appropriate diagnostic work-up of CTEPH is rarely undertaken. The study, “CTEPH: a…
Low activity levels in a small RNA molecule called miR126 may be implicated in vascular remodeling — a hallmark feature of pulmonary hypertension (PH) — in the lungs of chronic obstructive pulmonary disease (COPD) patients regardless of whether or not they also have PH, a study reported. This…
People with pulmonary hypertension (PH) who had elevated blood levels of the trimethylamine N-oxide (TMAO) molecule were at a five times greater risk of a poor prognosis than patients who didn’t have high levels, according to a recent study. High levels of this gut-derived metabolite were generally linked to…
Two new biomarkers to assess pulmonary arterial hypertension (PAH) were discovered through large-scale analysis of gene activity profiles using computer software, a study reported. These biomarkers, the activity of the genes PNISR and HNRNPH1, may help diagnose PAH, monitor its progression, or measure responses to therapy. They also may highlight…
People with pulmonary arterial hypertension (PAH) may lack some key vitamins and minerals their bodies need daily to stay healthy, which may lessen their vitality, according to a small study from the Netherlands. Besides the known lack of vitamin D and iron, researchers observed lower than recommended levels of…
Over the past year, the team here at Pulmonary Hypertension News has brought you up-to-date coverage of the latest developments in research, care, and treatment related to pulmonary hypertension (PH). We hope to continue to be a resource for the PH community in the coming year. Here is a…
Increasing the levels of the Tex261 protein — either as a preventive or therapeutic approach — eased the symptoms of pulmonary arterial hypertension (PAH) in a rat model of the disease, a new study shows. These benefits were seen after the scientists had found that PAH development in…
Dosing is complete in a Phase 1 clinical trial of AER-901, Aerami Therapeutics’ inhaled formulation of imatinib that’s being investigated to treat pulmonary arterial hypertension (PAH). Aerami plans to advance the experimental therapy to a proof-of-concept Phase 2 trial in the first half of 2023. To do so,…
Unhealthy changes in cognition, like a focus on worries, can lead to anxiety in people with pulmonary hypertension(PH), while those in behavior, like social avoidance, may cause depression, according to a U.K. study. Greater dyspnea, or shortness of breath, was also a contributing factor when paired with these cognitive or…
Infants with pulmonary arterial hypertension (PAH) who were put on Adempas (riociguat) after Revatio (sildenafil) and other therapies failed to control their symptoms showed improvements in lung and right heart function, according to data from a small study. They also had a reduction in high blood pressure…
