Inappropriate Exercise-Induced Increase in Pulmonary Artery Pressure in Patients With Systemic Sclerosis

Study Questions:

After evaluating pulmonary artery systolic pressure (PASP) and right ventricular (RV) function at baseline and immediately following exercise in patients with systemic sclerosis (SS) who do not have evidence of resting pulmonary arterial hypertension (PAH), is there an increase in PASP after exercise?
