Heart, heartjnl-2025-326053. https://doi.org/10.1136/heartjnl-2025-3260531355-60371468-201Xhttps://hdl.handle.net/11268/16395Current evidence supports the role of circulating carbohydrate antigen 125 (CA125) in risk assessment, disease monitoring and therapeutic guidance in heart failure (HF). However, there is limited data on its diagnostic applicability. This study aimed to assess the diagnostic performance of CA125 in identifying HF with preserved ejection fraction (HFpEF) in an outpatient population.engAntígeno Ca-125Infarto del MiocardioEstudio Multicéntricojournal article10.1136/heartjnl-2025-326053embargoed accessSistema cardiovascularEnfermedad cardiovascularInvestigación médicaGoal 3: Ensure healthy lives and promote well-being for all at all ages
