Eosinophils Reduce Inflammation, Cell Overgrowth in PH: Study

Immune cells called eosinophils help protect against the progression of pulmonary hypertension (PH) by reducing lung inflammation and regulating the growth of muscle cells around blood vessels, a new study indicates. The study, “Eosinophils Protect Against Pulmonary Hypertension through 14-HDHA and 17-HDHA,” was published in the …

Study Ties anti-VEGF Therapies to PH in Preterm Newborns

Premature newborns who are treated for eye problems with anti-VEGF therapies may be at increased risk of developing pulmonary hypertension, a new study suggests. “Future studies evaluating the safety of anti-VEGF therapy should include pulmonary hypertension as a key clinical outcome. This is especially important as anti-VEGF treatment usage…

CorVista Device to Diagnose PH Gets FDA Breakthrough Designation

The U.S. Food and Drug Administration (FDA) granted breakthrough device designation to the CorVista System, a point-of-care diagnostic tool that aims to use non-invasive tests and machine learning to help diagnose pulmonary hypertension and other cardiovascular disorders. The designation gives CorVista Health, the system’s developer, certain benefits aimed…

Higher Tyvaso Doses Better at Preventing PH-ILD Worsening

A high dose of Tyvaso (inhaled treprostinil) — at least nine breaths four times per day — is more effective at preventing clinical worsening than lower doses for people with pulmonary hypertension associated with interstitial lung disease (PH-ILD), a new study indicates. “This analysis further reinforces that [Tyvaso]…

Pulnovo’s PADN Device Yields Improved Outcomes in PAH Trial

Treatment with Pulnovo Medical‘s pulmonary artery denervation (PADN) device improved exercise capacity, blood flow dynamics, and clinical outcomes for pulmonary arterial hypertension (PAH) patients in a clinical trial called PADN-CFDA, the company announced. “The PADN-CFDA results are very important because this was an adequately powered randomized controlled trial,…
