In this single\u2010center study, we evaluated the clinical, neurohumoral, echocardiographic and hemodynamic correlates and prognostic value of the ALBI score, and to assess whether this score offers an incremental benefit over the Registry to EValuate Early And Long\u2010term pulmonary arterial hypertension disease management (REVEAL) 2.0 risk score in patients with PAH. This study evaluated the prognostic value of the ALBI score and its incremental benefit in a cohort of 380 PAH patients (mean age 47.6\u2009\u00b1\u200918.3 years, 74.3% female). Patients were stratified into low (&lt;= \u22122.60) and high (&gt; \u22122.60) ALBI groups. High ALBI scores were significantly associated with worse functional class, reduced exercise capacity, elevated Nt\u2010proBNP, right ventricular systolic dysfunction, and vena cava plethora (all\n                    <jats:italic>p\u2009<\/jats:italic>\n                    &lt;\u20090.001). Hemodynamically, elevated ALBI correlated with increased right atrial pressure (RAP) (\n                    <jats:italic>p\u2009<\/jats:italic>\n                    =\u20090.005), reduced cardiac index (\n                    <jats:italic>p\u2009<\/jats:italic>\n                    =\u20090.002), and a narrowed trans\u2010systemic pressure gradient (\n                    <jats:italic>p\u2009<\/jats:italic>\n                    =\u20090.001). Multivariable Cox regression demonstrated that ALBI was an independent predictor of mortality [Adjusted HR: 1.80 (95% CI: 1.30\u20132.49),\n                    <jats:italic>p\u2009<\/jats:italic>\n                    &lt;\u20090.001], outperforming MELD variants and the FIB\u20104 index. Integrating ALBI into REVEAL 2.0 yielded higher risk discrimination (C\u2010index: 0.756) than adding direct echocardiographic indices of right ventricular function or coupling (C\u2010indices: 0.748\u20130.749). In sensitivity analyses adjusting for TAPSE\/PASP, invasive cardiac index, mean RAP, and background therapy, ALBI maintained its independent prognostic value [Adjusted HR: 1.44 (95% CI: 1.01\u20132.05),\n                    <jats:italic>p\u2009<\/jats:italic>\n                    =\u20090.044], with the full model achieving a C\u2010index of 0.801. Within the REVEAL 2.0 intermediate\u2010risk subgroup, a high ALBI score identified patients with a three\u2010fold higher mortality risk [HR: 3.04 (95% CI: 1.25\u20137.38),\n                    <jats:italic>p\u2009<\/jats:italic>\n                    =\u20090.014], improving discriminative performance by 26.3%. The ALBI score independently predicts mortality beyond standard pulmonary hemodynamics and echocardiographic right ventricular parameters. Incorporating ALBI into REVEAL 2.0 enhances survival prediction and aids risk refinement in intermediate\u2010risk PAH.\n
