To the Editor:

We read with great interest the study of Alkotob et al (July 2006)1 on pulmonary hypertension (PHTN) in patients with scleroderma. They demonstrate that stress-induced pulmonary systolic hypertension in patients with scleroderma is highly prevalent, 46%, defined by an abnormal rise in pulmonary artery systolic pressure (PASP) > 40 mm Hg during exercise. The question is: are really all these patients a risk population of PHTN?

Knowledge of the risk for the development PHTN is essential. Chang et
