Abstract: Pulmonary arterial hypertension (PAH) prognosis has improved with targeted therapies although the long-term outlook remains poor. Objective multi-parametric risk assessment is recommended to identify patients at risk of early morbidity and mortality, and for optimization of treatment. The REVEAL 2.0 Risk Score is a new model proposed for the follow-up of PAH patients but has not been externally validated. The REVEAL 2.0 Risk Score was applied to a mixed prevalent and incident cohort of PAH patients (n=1,011) from the Pulmonary Hypertension Society of Australia and New Zealand (PHSANZ) Registry. Kaplan-Meier (KM) survival was estimated for each REVEAL 2.0 Risk Score strata and for a broader three-category (low, intermediate, high-risk) model. Sensitivity analysis was performed on an incident-only cohort. The REVEAL 2.0 model effectively discriminated risk in the large external PHSANZ registry cohort, with c-statistic 0.74 (both for full 8-tier and three-category models). When applied to incident cases only, c-statistic was 0.73. The three-category REVEAL 2.0 model demonstrated robust separation of 12 and 60-months survival estimates (all risk categories comparisons p<0.001). Although the full 8-tier REVEAL 2.0 model separated low, intermediate and high-risk patients, survival estimates overlapped within some of the intermediate and high-risk strata. The REVEAL 2.0 risk score was validated in a large external cohort from the PHSANZ Registry. The REVEAL 2.0 model can be applied for risk assessment of PAH patients at follow-up. The simplified 3-category model may be preferred for clinical use and for future comparison with other prognostic models.
