- Abstract
Objective: Early detection of pulmonary arterial hypertension (PAH) is crucial for improving patient outcomes. The aim of this study was to compare the positive predictive value (PPV) of the echocardiography-derived tricuspid annular plane systolic excursion/systolic pulmonary artery pressure (TAPSE/sPAP) ratio with that of the DETECT algorithm for PAH screening in a cohort of SSc patients., Methods: Fifty-one SSc patients were screened for PAH using the DETECT algorithm and echocardiography., Results: Echocardiography was recommended by the DETECT algorithm step 1 in 34 patients (66.7%). Right heart catheterization (RHC) was recommended by the DETECT algorithm step 2 in 16 patients (31.4%). PAH was confirmed by RHC in 5 patients. The DETECT algorithm PPV was 31.3%. The TAPSE/sPAP ratio was higher in SSc patients not referred for RHC than in SSc patients referred for RHC according to the DETECT algorithm step 2 [0.83 (0.35-1.40) mm/mmHg vs 0.74 (0.12-1.09) mm/mmHg, P < 0.05]. Using a cut-off of 0.60 mm/mmHg, 8 (15.7%) SSc patients had a TAPSE/sPAP ratio of ≤0.60 mm/mmHg. PAH was confirmed by RHC in 5 patients. The PPV of TAPSE/sPAP was 62.5%. In multiple regression analysis, TAPSE/sPAP was associated with age [β coefficient = -0.348 (95% CI: -0.011, -0.003); P < 0.01], DETECT algorithm step 1 [β coefficient = 1.023 (95% CI: 0.006, 0.024); P < 0.01] and DETECT algorithm step 2 (β coefficient = -1.758 [95% CI: -0.059, -0.021]; P < 0.0001)., Conclusion: In SSc patients with a DETECT algorithm step 2 total score of >35, the TAPSE/sPAP ratio can be used to further select patients requiring RHC to confirm PAH diagnosis., (© The Author(s) 2021.
