Dépistage de l’hypertension artérielle pulmonaire au cours de la sclérodermie systémique : comparaison de l’algorithme DETECT à une discussion pluridisciplinaire en centre de compétence [Screening for pulmonary arterial hypertension in patients with systemic sclerosis: Comparison of DETECT algorithm to decisions of a multidisciplinary team, in a competence centre]

National audienceINTRODUCTION: Pulmonary arterial hypertension (PAH) is a severe complication of systemic sclerosis and detecting PAH efficiently remains challenging. The DETECT study has offered in 2013 a composite screening tool for PAH. The objective of our study was to compare the indication of right heart catheterisation (RHC) as suggested by the DETECT algorithm with the decisions of a multidisciplinary team. METHODS: This prospective monocentric non-interventional study consecutively included systemic sclerosis patients when data required to apply DETECT algorithm were available. We evaluate the number of RHC as requested by this algorithm and confronted it with the indications of RHC suggested by a multidisciplinary group blinded for the result of DETECT algorithm. RESULTS: In total, 117 systemic sclerosis patients were included. When DETECT algorithm was applied to all patients, RHC was suggested by this algorithm for 70 patients, whereas only 15 indications were required by the multidisciplinary group; among those patients only 7 had PAH. When DETECT algorithm was applied only to the 42 patients with DLCO
