Prevalence, Clinical Characteristics, and Prognostic Impact of Kidney Disease on Heart Failure Patients: An Observational Study of the Colombian Heart Failure Registry

Abstract Introduction: Chronic kidney disease (CKD) represents one of the most frequent comorbidities observed in heart failure (HF) patients and has been observed to increase this population’s risk of adverse outcomes. Nevertheless, evidence analyzing kidney dysfunction in HF is scarce in Latin American populations. We aimed to analyze the prevalence of kidney dysfunction and assess its association with mortality in patients diagnosed with HF enrolled in the Colombian Heart Failure Registry (RECOLFACA). Methods: RECOLFACA enrolled adult patients with HF diagnosis from 60 centers in Colombia during the period 2017–2019. The primary outcome was all-cause mortality. A Cox proportional-hazards regression model was used to assess the impact of the different categories of eGFR in mortality risk. A p value of
