The aim of the study was to develop and validate a UK risk score to predict prognosis in PAH.<\/jats:p><jats:p>Baseline mortality predictors identified by multivariate Cox analysis in 182 incident PAH patients were used to derive the Scottish composite score (SCS). Its prognostic performance in an independent UK cohort was compared with the French registry and Pulmonary Hypertension Connection (PHC) registry equations using Brier scores (BS).<\/jats:p><jats:p>The SCS based on age, sex, aetiology, right atrial pressure, cardiac output and 6-min walk distance predicted survival in the validation cohort (hazard ratio (HR) 1.7 per point increase; p&lt;0.001) and provided further prognostic stratification in World Health Organization (WHO) functional class III patients (HR 1.8 per point increase; p&lt;0.001). It was more accurate than the French registry equation in predicting 1-yr survival (BS: 0.092<jats:italic>versus<\/jats:italic>0.146; p=0.001) and 2-yr survival (0.131<jats:italic>versus<\/jats:italic>0.255; p&lt;0.001).
