Abstract excerpt

BACKGROUND: CTD-PAH is a heterogeneous condition with poor prognosis. While systemic sclerosis predominates in Western cohorts, systemic lupus erythematosus is a major contributor in Saudi Arabia and other non-Western regions. However, data on phenotypes, outcomes, and longitudinal risk stratification in Middle Eastern CTD-PAH remain limited. This study characterized CTD-PAH in a Saudi cohort and identified...
