Signs Your PAH Treatment Isn’t Working

Pulmonary arterial hypertension (PAH) results in high blood pressure in the lungs due to small lung arteries becoming thick and narrow. Many treatments are available, including vasodilators, anticoagulant medications, diuretics, digoxin, oxygen treatment, and in some cases, surgery. The goal is to ease symptoms and slow the progress of the condition. Success of treatment can be measured by doctor assessments on a functional class scale, exercise capacity levels, and other tests.
