Blood Levels of Certain Metabolites May Help Diagnose SSc-PAH: Study
The levels of certain metabolites — molecules that take part in metabolism — circulating in the blood may help differentiate pulmonary arterial hypertension (PAH) due to scleroderma (SSc-PAH) from idiopathic PAH, a new study shows. The “metabolic signature” correlated with worse disease severity in PAH tied to SSc.
