Description

The disability of a patient with pulmonary arterial hypertension can be graded based on the level of functional impairment. This scale is a modification of the New York Heart Association (NYHA) functional classification for patients with heart disease. The scale was proposed at the World Symposium on Primary Pulmonary Hypertension in Evian, France.
