RESUMO

Introducción y objetivos: Los inhibidores del cotransportador 2 de sodio-glucosa (iSGLT2) inducen cambios a corto plazo en la función renal y la hemoglobina y su fisiopatología se comprende de manera incompleta. Nuestro objetivo es evaluar la relación entre los cambios de la tasa de filtrago glomerular estimado (TFGre) y la hemoglobina tras el inicio de dapagliflozina en pacientes estables con insuficiencia cardiaca y fracción de eyección reducida (IC-FEr). Métodos: Este análisis post hoc de un ensayo clínico aleatorizado evaluó el efecto de la dapagliflozina sobre el consumo máximo de oxígeno a 1 y 3 meses en pacientes ambulatorios con IC-FEr estable (ensayo DAPA-VO2, NCT04197635). Se utilizó un análisis de regresión lineal mixta para evaluar la relación entre los cambios en la TFGe y la hemoglobina a 1 y 3 meses. Resultados: Se evaluó a 87 pacientes. La media de edad era 67,0±10,5 años, y 21 pacientes (24,1%) eran mujeres. Las medias basales de TFGe y hemoglobina fueron de 66,9±20,7ml/min/1,73 m2 y 14,3±1,7g/dl respectivamente. En comparación con el placebo, la TFGe no cambió significativamente en el grupo de dapagliflozina, pero la hemoglobina aumentó significativamente a 1 y 3 meses. A 1 mes, el aumento de la hemoglobina se relacionó con la disminución de la TFGe solo en el grupo de dapagliflozina (p <0,001). A los 3 meses no había asociación significativa (p=0,123). Los cambios de la TFGe a 1 y 3 meses no se asociaron con cambios en el consumo pico de oxígeno, la calidad de vida o los péptidos natriuréticos. Conclusiones: En pacientes con IC-FEr estable, los cambios en la TFGe a 1 mes inducidos por la dapagliflozina están en relación inversa con cambios en la hemoglobina. Esta asociación no se observa a los 3 meses. (AU)


Introduction and objectives: Sodium-glucose cotransporter-2 inhibitors (SGLT2i) induce short-term changes in renal function and hemoglobin. Their pathophysiology is incompletely understood. We aimed to evaluate the relationship between 1- and 3-month estimated glomerular filtration rate (eGFR) and hemoglobin changes following initiation of dapagliflozin in patients with stable heart failure with reduced ejection fraction (HFrEF). Methods: This is a post hoc analysis of a randomized clinical trial that evaluated the effect of dapagliflozin on 1- and 3-month peak oxygen consumption in outpatients with stable HFrEF (DAPA-VO2 trial, NCT04197635). We used linear mixed regression analysis to assess the relationship between eGFR and hemoglobin changes across treatment arms. Results: A total of 87 patients were evaluated in this substudy. The mean age was 67.0± 10.5 years, and 21 (24.1%) were women. The mean baseline eGFR and hemoglobin were 66.9±20.7mL/min/1.73m2 and 14.3±1.7g/dL, respectively. Compared with placebo, eGFR did not significantly change at either time points in the dapagliflozin group, but hemoglobin significantly increased at 1 and 3 months. At 1 month, the hemoglobin increase was related to decreases in eGFR only in the dapagliflozin arm (P <.001). At 3 months, there was no significant association in either treatment arms (P=.123). Changes in eGFR were not associated with changes in peak oxygen consumption, quality of life, or natriuretic peptides. Conclusions: In patients with stable HFrEF, 1-month changes in eGFR induced by dapagliflozin are inversely related to changes in hemoglobin. This association was no longer significant at 3 months.

RESUMO

BACKGROUND: Some studies have indicated that sodium-glucose cotransporter-2 (SGLT2) inhibitors promote an increase in cell iron use. OBJECTIVES: The aim of this study was to examine, in patients with stable heart failure with reduced left ventricular ejection fraction (HFrEF), the effect of dapagliflozin on ferrokinetic parameters and whether short-term changes in peak oxygen consumption (Vo2) after dapagliflozin treatment are influenced by baseline and serial ferrokinetic status. METHODS: This was an exploratory analysis of a randomized, double-blind clinical trial that evaluated the effect of dapagliflozin vs placebo on peak Vo2 in patients with HFrEF (NCT04197635) and included 76 of the 90 patients initially enrolled in the trial. Changes in peak Vo2 at 1 and 3 months were explored according to baseline and longitudinal ferrokinetic parameters (natural logarithm [ln] ferritin, transferrin saturation index [TSAT], soluble transferrin receptor, and hepcidin). Linear mixed-effect regression was used for the analyses. RESULTS: Compared with placebo, dapagliflozin led to a significant decrease in 3-month ln ferritin (P = 0.040) and an increase in 1-month ln soluble transferrin receptor (P = 0.023). Between-treatment comparisons revealed a stepwise increase in peak Vo2 in the dapagliflozin group at 1 and 3 months, which was especially apparent at lower baseline values of TSAT and ferritin (P < 0.05). Lower time-varying values of TSAT (1 and 3 months) also identified patients with greater improvements in peak Vo2. CONCLUSIONS: In patients with stable HFrEF, treatment with dapagliflozin resulted in short-term increases in peak Vo2, which were most marked in patients with surrogates of greater iron deficiency at baseline and during treatment. (Short-Term Effects of Dapagliflozin on Peak Vo2 in HFrEF [DAPA-VO2]; NCT04197635).

RESUMO

Introducción y objetivos: Poco se sabe sobre la utilidad de la respuesta de la frecuencia cardiaca (FC) al ejercicio para la estratificación del riesgo en la insuficiencia cardiaca con fracción de eyección conservada (ICFEc). El objetivo de este estudio fue evaluar la asociación entre la respuesta de la FC al ejercicio y el riesgo de episodios de descompensación por insuficiencia cardiaca (DIC) en pacientes sintomáticos estables con ICFEc. Métodos: Se trata de un estudio unicéntrico que incluyó a un total de 133 pacientes con ICFEc (NYHA II-III) tras la realización de una prueba de esfuerzo cardiopulmonar máxima. La respuesta de la FC al ejercicio se evaluó mediante la fórmula del índice cronotrópico (IxC). Para el análisis se utilizó un método de regresión binomial negativa. Resultados: La edad media fue de 73,2±10,5 años, el 56,4% eran mujeres y el 51,1% estaban en fibrilación auricular. La mediana de IxC fue de 0,4 (0,3-0,55). Tras una mediana de seguimiento de 2,4 (1,6-5,3) años, se registraron un total de 146 DIC en 58 pacientes y 41 (30,8%) muertes. El IxC no se asoció con eventos adversos (muerte, p=0,319, y DIC, p=0,573) cuando se analizó de forma conjunta toda la muestra. Sin embargo, se encontró un efecto diferencial en función del ritmo electrocardiográfico para DIC (p para interacción=0,002). El IxC se asoció inversa y linealmente con el riesgo de DIC en aquellos pacientes con ritmo sinusal y de forma lineal y positiva con aquellos en fibrilación auricular. Conclusiones: En pacientes con ICFEc, el IxC se asoció diferencialmente con el riesgo de DIC en función del ritmo electrocardiográfico. Un Ixc más bajo surgió como un factor de riesgo para predecir un mayor riesgo de DIC en pacientes en ritmo sinusal. Por el contrario, un IxC más alto identificó un mayor riesgo en aquellos pacientes en fibrilación auricular. (AU)


Introduction and objectives: Little is known about the usefulness of heart rate (HR) response to exercise for risk stratification in heart failure with preserved ejection fraction (HFpEF). Therefore, this study aimed to assess the association between HR response to exercise and the risk of total episodes of worsening heart failure (WHF) in symptomatic stable patients with HFpEF. Methods: This single-center study included 133 patients with HFpEF (NYHA II-III) who performed maximal cardiopulmonary exercise testing. HR response to exercise was evaluated using the chronotropic index (CIx) formula. A negative binomial regression method was used. Results: The mean age of the sample was 73.2± 10.5 years; 56.4% were female, and 51.1% were in atrial fibrillation. The median for CIx was 0.4 [0.3-0.55]. At a median follow-up of 2.4 [1.6-5.3] years, a total of 146 WHF events in 58 patients and 41 (30.8%) deaths were registered. In the whole sample, CIx was not associated with adverse outcomes (death, P=.319, and WHF events, P=.573). However, we found a differential effect across electrocardiographic rhythms for WHF events (P for interaction=.002). CIx was inversely and linearly associated with the risk of WHF events in patients with sinus rhythm and was positively and linearly associated with those with atrial fibrillation. Conclusions: In patients with HFpEF, CIx was differentially associated with the risk of total WHF events across rhythm status. Lower CIx emerged as a risk factor for predicting higher risk in patients with sinus rhythm. In contrast, higher CIx identified a higher risk in those with atrial fibrillation. (AU)

RESUMO

La congestión desempeña un papel fundamental en la patogénesis, la presentación y el pronóstico de la insuficiencia cardiaca y es un objetivo terapéutico importante. Sin embargo, su gravedad y su distribución por órganos y compartimentos varían mucho entre los pacientes, lo que ilustra la complejidad de este fenómeno. Aunque los síntomas y signos clínicos son útiles para evaluar la congestión y controlar el estado del volumen en un paciente individual, tienen poca sensibilidad y no permiten fenotipificar la congestión. Esto conduce a la incertidumbre diagnóstica y dificulta la toma de decisiones terapéuticas. En este artículo se ofrece una visión general actualizada de los biomarcadores circulantes, las modalidades de imagen (es decir, la ecografía cardiaca y extracardiaca) y las técnicas invasivas que podrían ayudar a los clínicos a identificar los diferentes perfiles de congestión y guiar la estrategia de tratamiento para esta población diversa de pacientes de alto riesgo con insuficiencia cardiaca.(AU)


Congestion plays a major role in the pathogenesis, presentation, and prognosis of heart failure and is an important therapeutic target. However, its severity and organ and compartment distribution vary widely among patients, illustrating the complexity of this phenomenon. Although clinical symptoms and signs are useful to assess congestion and manage volume status in individual patients, they have limited sensitivity and do not allow identification of congestion phenotype. This leads to diagnostic uncertainty and hampers therapeutic decision-making. The present article provides an updated overview of circulating biomarkers, imaging modalities (ie, cardiac and extracardiac ultrasound), and invasive techniques that might help clinicians to identify different congestion profiles and guide the management strategy in this diverse population of high-risk patients with heart failure.(AU)

RESUMO

BACKGROUND: The prediction of sudden cardiac death (SCD) in heart failure (HF) remains an unmet need. The aim of our study was to assess the prevalence of SCD over 20 years in outpatients with HF managed in a Mediterranean multidisciplinary HF Clinic, and to compare the proportion of SCD (SCD/all-cause death) to the expected proportional occurrence based on the validated Seattle Proportional Risk Model (SPRM) score. METHODS AND RESULTS: This prospective observational registry study included 2772 outpatients with HF admitted between August 2001 and May 2021. Patients were included when the cause of death was known and SPRM score was available. Over the 20-year study period, 1351 patients (48.7%) died during a median follow-up period of 3.8 years (interquartile range 1.6-7.6). Among these patients, the proportion of SCD out of the total of deaths was 13.6%, whereas the predicted by SPRM was 39.6%. This lower proportion of SCD was observed independently of left ventricular ejection fraction, ischemic etiology, and the presence of an implantable cardiac defibrillator. CONCLUSIONS: In a Mediterranean cohort of outpatients with HF, the proportion of SCD was lower than expected based on the SPRM score. Future studies should investigate to what extend epidemiological and guideline-directed medical therapy patterns influence SCD.

RESUMO

La retención renal de sodio y agua, con la consiguiente expansión y redistribución del volumen de líquido extracelular, constituye una de las principales características fisiopatológicas de la insuficiencia cardiaca. No obstante, la detección, monitorización y manejo de la congestión continúa representando un verdadero desafío para el clínico. En el presente documento se revisa la literatura histórica y contemporánea acerca de los métodos disponibles para evaluar la congestión desde una perspectiva clínica e integradora, y se discuten aspectos farmacológicos y principios fisiopatológicos fundamentales para el uso óptimo de la terapia con diuréticos. (AU)


Renal sodium and water retention with resulting extracellular volume expansion and redistribution are hallmark features of heart failure syndromes. However, congestion assessment, monitoring, and treatment represent a real challenge in daily clinical practice. This document reviewed historical and contemporary evidence of available methods for determining volume status and discuss pharmacological aspects and pathophysiological principles that underlie diuretic use.

RESUMO

BACKGROUND: Right heart dysfunction (RHD) parameters are increasingly important in heart failure (HF). This study aimed to evaluate the association of advanced RHD with the risk of recurrent admissions across the spectrum of left ventricular ejection fraction (LVEF). METHODS AND RESULTS: We included 3383 consecutive patients discharged for acute HF. Of them, in 1435 patients (42.4%), the pulmonary artery systolic pressure could not be measured accurately, leaving a final sample size of 1948 patients. Advanced RHD was defined as the combination of a ratio of tricuspid annular plane systolic excursion/pulmonary artery systolic pressure of less than 0.36 and significant tricuspid regurgitation (n = 196, 10.2%). Negative binomial regression analyses were used to evaluate the risk of recurrent admissions. At a median follow-up of 2.2 years (interquartile range 0.63-4.71), 3782 readmissions were registered in 1296 patients (66.5%). Patients with advanced RHD showed higher readmission rates, but only if the LVEF was 40% or greater (P < .001). In multivariable analyses, this differential association persisted for cardiovascular and HF recurrent admissions (P value for interaction = .015 and P = .016; respectively). Advanced RHD was independently associated with the risk of recurrent cardiovascular and HF admissions if HF with an LVEF of 40% or greater (incidence rate ratio 1.64, 95% confidence interval 1.18-2.26, P = .003; and incidence rate ratio 1.73; 95% confidence interval 1.25-2.41, P = .001;respectively). In contrast, it was not associated with readmission risks if the LVEF was less than 40%. CONCLUSIONS: After an admission for acute HF, advanced RHD was strongly associated with a higher risk of recurrent cardiovascular and HF admissions, but only in patients with an LVEF of 40% or greater.

RESUMO

Antecedentes: El antígeno carbohidrato 125 (CA125) y los péptidos natriuréticos tipo B son marcadores subrogados de congestión en pacientes con insuficiencia cardíaca aguda (ICA). El objetivo del estudio fue valorar la asociación entre CA125 y NT-proBNP y parámetros de congestión en pacientes con ICA.Métodos y resultadosEstudio observacional prospectivo multicéntrico, que incluyó a 191 pacientes hospitalizados por ICA. Se registró la presencia de derrame pleural, edema periférico y diámetro de vena cava inferior (VCI) durante las primeras 24-48 horas tras el ingreso y se evaluó su asociación independiente con las concentraciones de CA125 y la fracción amino-terminal del péptido natriurético tipo B (NT-proBNP). La edad media fue de 73,4 ± 12 años, 79 (41,4%) eran mujeres y 127 (66,5%) tenían fracción de eyección ventricular izquierda ≥ 50%. La mediana de CA125, NT-proBNP y diámetro VCI fue de 58 (22,7-129) U/mL, 3.985 (1.905-9.775) pg/mL y 21 (17-25) mm, respectivamente. El análisis multivariante mostró que el CA125 se asoció positiva e independientemente con presencia de edema periférico, derrame pleural y valores elevados de VCI. El NT-proBNP se relacionó con el derrame pleural y el diámetro de VCI, pero no con el edema. La adición del CA125 incrementó la capacidad discriminativa del modelo basal para identificar edema periférico y derrame pleural, no así el NT-proBNP. El predictor más importante para la dilatación de la VCI fue el CA125 (R2 = 48,3%).ConclusiónEn pacientes con ICA, los niveles séricos de CA125 se asocian de forma más significativa que los de NT-proBNP con el estado de congestión.

Background: Carbohydrate antigen 125 (CA125) and B-type natriuretic peptides are surrogate markers of congestion in patients with acute heart failure (AHF). The aim of the study was to assess the association between CA125 and NT-proBNP and congestion parameters in patients with AHF.Methods and resultsProspective multicentre observational study that included 191 patients hospitalised for AHF. We recorded the presence of pleural effusion, peripheral oedema and inferior vena cava (IVC) diameter during the first 24-48 hours after admission and evaluated their independent association with CA125 concentrations and the amino-terminal fraction of pro-B-type natriuretic peptide (NT-proBNP). The mean age was 73.4 ± 12 years, 79 (41.4%) were women, and 127 (66.5%) had left ventricular ejection fraction ≥ 50%. The median of CA125, NT-proBNP and IVC diameter was 58 (22.7-129) U/mL, 3,985 (1,905-9,775) pg/mL and 21 (17-25) mm, respectively. Multivariate analysis showed that CA125 was positively and independently associated with the presence of peripheral oedema, pleural effusion and elevated IVC levels. NT-proBNP was associated with pleural effusion and IVC diameter but not with oedema. The addition of CA125 increased the discriminatory capacity of the baseline model to identify peripheral oedema and pleural effusion, but not NT-proBNP. The most important predictor of ICV dilation was CA125 (R2 = 48.3%).ConclusionIn patients with AHF, serum CA125 levels are associated more significantly than NT-proBNP with a state of congestion.

RESUMO

BACKGROUND: Identifying patients at risk of poor diuretic response in acute heart failure (AHF) is critical to make prompt adjustments in therapy. The objective of this study was to investigate whether the circulating levels of soluble ST2 predict the cumulative diuretic efficiency (DE) at 24 and 72 hours in patients with AHF and concomitant renal dysfunction. METHODS AND RESULTS: This is a post hoc analysis of the IMPROVE-HF trial, in which we enrolled 160 patients with AHF and renal dysfunction (estimated glomerular filtrate rate of <60 mL/min/1.73 m2). DE was calculated as the net fluid output produced per 40 mg of furosemide equivalents. The association between sST2 and DE was evaluated by using multivariate linear regression analysis. The median cumulative DE at 24 and 72 hour was 747 mL (interquartile range 490-1167 mL) and 1844 mL (interquartile range 1142-2625 mL), respectively. The median sST2 and mean estimated glomerular filtrate rate were 72 ng/mL (interquartile range 47-117 ng/mL), and 34.0 ± 8.5 mL/min/1.73 m2, respectively. In a multivariable setting, higher sST2 were significant and nonlinearly related to lower DE both at 24 and 72 hours (P = .002 and P = .019, respectively). CONCLUSIONS: In patients with AHF and renal dysfunction at presentation, circulating levels of sST2 were independently and negatively associated with a poor diuretic response, both at 24 and 72 hours.

RESUMO

INTRODUCCIÓN Y OBJETIVOS: La diabetes mellitus tipo 2 (DM2) es una comorbilidad común en pacientes con insuficiencia cardiaca (IC) con fracción de eyección conservada (ICFEP). Estudios anteriores han demostrado que las mujeres diabéticas tienen mayor riesgo de desarrollar insuficiencia cardiaca que los hombres. Sin embargo, el pronóstico a largo plazo de los pacientes diabéticos con insuficiencia cardiaca en función del sexo no se ha explorado ampliamente. En este estudio, nuestro objetivo fue evaluar el impacto diferencial de la DM2 en la mortalidad por todas las causas en hombres frente a mujeres con ICFEP tras un ingreso por IC aguda. MÉTODOS: Se incluyeron prospectivamente 1.019 pacientes consecutivos con ICFEP dados de alta tras un episodio de IC aguda en hospital terciario. Se empleó un análisis de regresión de Cox multivariante para evaluar la interacción entre el sexo y la DM2 con respecto al riesgo de mortalidad total a largo plazo. Las estimaciones de riesgo se expresaron como razones de riesgo (HR). RESULTADOS: La edad media de la cohorte fue de 75,6±9,5 años y 609 (59,8%) eran mujeres. La proporción de DM2 fue similar entre ambos sexos (45,1 frente al 49,1%; p = 0,211). Tras una mediana de seguimiento (intervalo intercuartílico) de 3,6 (1-4-6,8) años, 646 (63,4%) pacientes murieron. Tras ajustar por factores de riesgo, comorbilidades, biomarcadores, parámetros ecográficos y tratamiento al alta, el análisis multivariate mostró un efecto pronóstico diferencial de DM2 (valor de p para la interacción=0,007). La DM2 se asoció con un mayor riesgo de mortalidad por todas las causas en mujeres (HR=1,77; IC95%, 1,41-2,21; p < 0,001) pero no en varones (HR=1,23; IC95%, 0,94-1,61; p = 0,127). CONCLUSIONES: Tras un episodio de IC aguda en pacientes con ICFEF, la DM2 confiere un mayor riesgo de mortalidad en las mujeres. Se requieren más estudios que evalúen el impacto de la DM2 en mujeres con ICFEP


INTRODUCTION AND OBJECTIVES: Type 2 diabetes mellitus (DM2) is a common comorbidity in patients with heart failure (HF) with preserved ejection fraction (HFpEF). Previous studies have shown that diabetic women are at higher risk of developing HF than men. However, the long-term prognosis of diabetic HFpEF patients by sex has not been extensively explored. In this study, we aimed to evaluate the differential impact of DM2 on all-cause mortality in men vs women with HFpEF after admission for acute HF. METHODS: We prospectively included 1019 consecutive HFpEF patients discharged after admission for acute HF in a single tertiary referral hospital. Multivariate Cox regression analysis was used to evaluate the interaction between sex and DM2 regarding the risk of long-term all-cause mortality. Risk estimates were calculated as hazard ratios (HR). RESULTS: The mean age of the cohort was 75.6±9.5 years and 609 (59.8%) were women. The proportion of DM2 was similar between sexes (45.1% vs 49.1%, P=.211). At a median (interquartile range) follow-up of 3.6 (1-4-6.8) years, 646 (63.4%) patients died. After adjustment for risk factors, comorbidities, biomarkers, echo parameters and treatment at discharge, multivariate analysis showed a differential prognostic effect of DM2 (P value for interaction=.007). DM2 was associated with a higher risk of all-cause mortality in women (HR, 1.77; 95%CI, 1.41-2.21; P<.001) but not in men (HR, 1.23; 95%CI, 0.94-1.61; P=.127). CONCLUSIONS: After an episode of acute HF in HFpEF patients, DM2 confers a higher risk of mortality in women. Further studies evaluating the impact of DM2 in women with HFpEF are warranted

RESUMO

Introducción y objetivos: El tratamiento óptimo de pacientes con insuficiencia cardiaca aguda (ICA) y síndrome cardiorrenal tipo 1 (SCR-1) no está bien definido. La hipoperfusión arterial y la congestión venosa tienen un papel fundamental en la fisiopatología del SCR-1. El antígeno carbohidrato 125 (CA125) ha emergido como marcador indirecto de sobrecarga de volumen en la ICA. El objetivo de este estudio es evaluar la utilidad del CA125 para el ajuste del tratamiento diurético de pacientes con SCR-1. Métodos: Ensayo clínico multicéntrico, abierto y paralelo, que incluye a pacientes con ICA y creatinina ≥ 1,4 mg/dl al ingreso, aleatorizados a: a) estrategia convencional: titulación basada en la evaluación clínica y bioquímica habitual, o b) estrategia basada en CA125: dosis altas de diuréticos si CA125 > 35 U/ml y bajas en caso contrario. El objetivo principal es el cambio en la función renal a las 24 y las 72 h tras el comienzo del tratamiento. Como objetivos secundarios: a) cambios clínicos y bioquímicos a las 24 y las 72 h, y b) cambios en la función renal y eventos clínicos mayores a 30 días. Resultados: Los resultados de este estudio aportarán datos relevantes sobre la utilidad del CA125 para guiar el tratamiento diurético en el SCR-1. Además, permitirá ampliar el conocimiento de la fisiopatología de esta compleja entidad clínica. Conclusiones: La hipótesis del presente estudio es que las concentraciones de CA125 aumentadas pueden identificar a una población de pacientes con SCR-1 para quienes una estrategia diurética más intensa puede ser beneficiosa. Por el contrario, las concentraciones bajas de esta glucoproteína seleccionarían a los pacientes para los que serían perjudiciales las dosis altas de diuréticos (AU)


Introduction and objectives: The optimal treatment of patients with acute heart failure (AHF) and cardiorenal syndrome type 1 (CRS-1) is far from being well-defined. Arterial hypoperfusion in concert with venous congestion plays a crucial role in the pathophysiology of CRS-I. Plasma carbohydrate antigen 125 (CA125) has emerged as a surrogate of fluid overload in AHF. The aim of this study was to evaluate the clinical usefulness of CA125 for tailoring the intensity of diuretic therapy in patients with CRS-1. Methods: Multicenter, open-label, parallel clinical trial, in which patients with AHF and serum creatinine ≥ 1.4 mg/dL on admission will be randomized to: a) standard diuretic strategy: titration-based on conventional clinical and biochemical evaluation, or b) diuretic strategy based on CA125: high dose if CA125 > 35 U/mL, and low doses otherwise. The main endpoint will be renal function changes at 24 and 72 hours after therapy initiation. Secondary endpoints will include: a) clinical and biochemical changes at 24 and 72 hours, and b) renal function changes and major clinical events at 30 days. Results: The results of this study will add important knowledge on the usefulness of CA125 for guiding diuretic treatment in CRS-1. In addition, it will pave the way toward a better knowledge of the pathophysiology of this challenging situation. Conclusions: We hypothesize that higher levels of CA125 will identify a patient population with CRS-1 who could benefit from the use of a more intense diuretic strategy. Conversely, low levels of this glycoprotein could select those patients who would be harmed by high diuretic doses (AU)
