Impacto Pronóstico de una Terapia Guiada por los Niveles Plasmáticos del Antígeno Carbohidrato 125 tras un Ingreso por Insuficiencia Cardiaca Aguda: Estudio Aleatorizado Introducción: La trayectoria de los niveles plasmáticos del antígeno carbohidrato 125 (CA125) se relaciona con la severidad y pronóstico tras un ingreso por insuficiencia cardíaca aguda (ICA). En este trabajo evaluamos la eficacia de una estrategia terapéutica guiada por los valores de CA125 (T-CA125) frente a un esquema terapéutico convencional (T-Conv). Métodos: Se aleatorizaron al alta 372 pacientes con ICA y valores elevados de CA125 (>35 U/ml) en 5 centros a T-CA125 (n=181) y a T-Conv (n=191). El objetivo de la T-CA125…
Optimal carbohydrate antigen 125 cutpoint for identifying low-risk patients after admission for acute heart failure
2022
Introduction and objectives: Carbohydrate antigen 125 (CA125) has been shown to be useful for risk stratification in patients admitted with acute heart failure (AHF). We sought to determine a CA125 cutpoint for identifying patients at low risk of 1-month death or the composite of death/HF readmission following admission for AHF.Methods: The derivation cohort included 3231 consecutive patients with AHF. CA125 cutoff values with 90% negative predictive value (NPV) and sensitivity up to 85% were identified. The adequacy of these cutpoints and the risk of 1-month death/HF readmission was then tested using the Royston-Parmar method. The best cutpoint was selected and externally validated in a co…
Early urinary sodium trajectory and risk of adverse outcomes in acute heart failure and renal dysfunction.
2021
Introduction and objectives: Urinary sodium (UNa+) has emerged as a useful biomarker of poor clinical outcomes in acute heart failure (AHF). Here, we sought to evaluate: a) the usefulness of a single early determination of UNa+ for predicting adverse outcomes in patients with AHF and renal dysfunction, and b) whether the change in UNa+ at 24 hours (Delta UNa24 h) adds any additional prognostic information over baseline values. Methods: This is a post-hoc analysis of a multicenter, open-label, randomized clinical trial (IMPROVE-HF) (ClinicalTrials.gov NCT02643147) that randomized 160 patients with AHF and renal dysfunction on admission to a) the standard diuretic strategy, or b) a carbohydra…
