Screening for pulmonary arterial hypertension in patients with systemic sclerosis in the era of new pulmonary arterial hypertension definitions.

With the recent criteria, PAH diagnosis in patients with SSc increased by 1.8-fold. Current algorithms for screening PAH are less sensitive with these revised criteria. Although the ASIG algorithm seems more sensitive, it can still miss the diagnosis. The multimodal/algorithmic approach seems to be the best option for predicting PAH.
