Pulmonary arterial hypertension (PAH) is a rapidly progressive disorder that is lethal if it remains undiagnosed and untreated. However, modern treatments represent a tremendous advance upon the therapies available just a few years ago and the prognosis for this life-threatening disease has changed. There is now good reason to ensure earlier diagnosis of PAH among systemic sclerosis (scleroderma) patients.
PAH is defined as a mean pulmonary artery pressure (PAP) exceeding 25 mmHg at rest or 30 mmHg during exercise. If left untreated between 45 and 60% of patients with PAH will die within 2 yr of diagnosis [1]. However, when it occurs as a manifestation of scleroderma PAH is particularly severe and 1-yr survival following diagnosis is approximately 55% [2]. Since scleroderma
