Abstract

OBJECTIVE:

The early, simple and reliable detection of pulmonary arterial hypertension (PAH) in SSc (DETECT) study described a new algorithm for early detection of PAH in patients with SSc. The aim of this retrospective, single-centre, cross-sectional study was to apply a modified DETECT calculator in patients with SSc in the East Bohemian region, Czech Republic, to assess the risk of PAH and to compare these results with PAH screening based on the European Society of Cardiology/European Respiratory Society (ESC/ERS) 2009 guidelines.

METHODS:

Sixty patients were recruited with a diagnosis of SSc (according to ACR criteria), aged 27-78 years. A modified DETECT algorithm using the modified parameter of (1.4 × right ventricle diameter)(2) in place of right atrium area was applied to all patients. Right heart catheterization (RHC) was performed in all patients with an estimated (by echocardiography) increased systolic pulmonary artery pressure ≥50 mm Hg in accordance with the ESC/ERS guidelines; however, RHC was not performed in patients solely recommended for RHC using the modified DETECT algorithm.

RESULTS:

Using the modified DETECT calculator, 24/58 (41.4%) patients were recommended for RHC, compared with 14/58 (24.1%) when applying the ESC/ERS 2009 guidelines. PAH was diagnosed in 7/58 (12.1%) patients. During follow-up, PAH was diagnosed in six patients. Of these, four were modified DETECT score-positive for 2 years and all for 1 year before PAH diagnosis.

CONCLUSION:

The modified DETECT algorithm detects all patients with PAH diagnosed according to ECS/ERS 2009 guidelines and RHC. Data of the 2-year follow-up indicate a possible positive predictive role for the modified DETECT calculator.
