Comparison of contemporary risk scores in all groups of pulmonary hypertension - a PVRI GoDeep meta-registry analysis

Chest. 2024 Mar 18:S0012-3692(24)00309-X. doi: 10.1016/j.chest.2024.03.018. Online ahead of print.ABSTRACTBACKGROUND: Pulmonary hypertension (PH) is a heterogeneous disease with poor prognosis. Accurate risk stratification is essential for guiding treatment decisions in pulmonary arterial hypertension (PAH). While various risk models were developed for PAH, their comparative prognostic potential requires further exploration. Additionally, the applicability of risk scores in PH groups beyond group 1 remains to be investigated.RESEARCH QUESTION: Are risk scores originally developed for PAH predictive in PH group 1-4?STUDY DESIGN AND METHODS: We conducted a comprehensive analysis of outcomes among incident PH patients enrolled in the multicenter worldwide PVRI-GoDeep meta-registry. Analyses were performed across PH groups 1-4 and further subgroups to evaluate the predictive value of PAH-risk scores, including REVEAL Lite 2, REVEAL 2.0, ESC/ERS 2022, COMPERA 3-strata and COMPERA 4-strata.RESULTS: 8565 patients were included in the study, of whom 3537 patients were assigned to group 1 PH while 1807, 1635, and 1586 patients were diagnosed with group 2, group 3, and group 4 PH. Pulmonary hemodynamics were impaired with median mPAP of 42 [33,52]mmHg and PVR of 7 [4,11]WU. All risk scores were prognostic in the entire PH population and in each of the PH groups 1-4. The REVEAL scores, when used as continuous prediction models, possessed the highest statistical prognostic power and gran...
