Purpose: Our objective was to review the evidence regarding echocardiography in patients with systemic sclerosis (SSc) and possible pulmonary hypertension (PH).

Methods: The literature was reviewed. In addition, a survey was conducted of 315 rheumatologists/internists with a self-declared interest in SSc, to determine their preferred use of echocardiograms.

Results: The most relevant literature findings come from two studies, the DETECT study and one from the Australian Scleroderma Interest Group. In both these studies, it appears that the use of non-echocardiographic variables such as pulmonary function tests (PFTs) and values of serum N-terminal pro-brain natriuretic peptide (NT-proBNP), are adequate on their own in suggesting which patients are at high risk of PH. Echocardiograms added very little information and in fact may confuse the picture by appearing to be normal when in fact underlying PH is present.
