Main pulmonary artery parameters predict PAH outcomes, study finds

A higher diameter and a faster enlargement rate of the body’s main pulmonary artery — dubbed the MPA, it carries oxygen-poor blood out of the heart toward the lungs — are independent predictors of poor outcomes among people with pulmonary arterial hypertension (PAH), a new study reports. In predicting…

Japanese Study Links Main Pulmonary Artery Dilation with Worse Outcomes in Pediatric PAH

Pulmonary artery dilation speeds up the progression of pediatric idiopathic and heritable pulmonary arterial hypertension (PAH), a Japanese study shows. Dilation of the main pulmonary artery (MPA) and narrowing of the peripheral pulmonary artery are both characteristic of PAH. Previous studies have shown that MPA dilation is linked to higher pulmonary artery…
