Diferencias en función del sexo en las características clínicas y resultados del ensayo clínico CLOROTIC (combinación de diuréticos de asa con tiazidas en la insuficiencia cardiaca descompensada) / Sex differences in clinical characteristics and outcomes in the CLOROTIC (combining loop with thiazide diuretics for decompensated heart failure) trial

ObjetivoEvaluar si existen diferencias en los resultados del ensayo clínico CLOROTIC según el sexo. Métodos Subanálisis del ensayo CLOROTIC, que evaluó la eficacia y la seguridad de añadir hidroclorotiazida (HCTZ) o placebo a furosemida intravenosa en pacientes con insuficiencia cardiaca aguda (ICA). Los resultados primarios y secundarios incluyeron cambios en el peso y la disnea a las 72 y 96horas, medidas de la respuesta diurética y la mortalidad y reingresos a los 30 y 90días. Se evaluó la influencia del sexo en los resultados primarios y secundarios y de seguridad. Resultados De los 230 pacientes incluidos, 111 (48%) eran mujeres, que tenían más edad y valores más elevados de fracción de eyección ventricular izquierda. Los hombres tenían más cardiopatía isquémica, enfermedad pulmonar obstructiva crónica y mayor valor de péptidos natriuréticos. La adición de HCTZ a furosemida se asoció con una mayor pérdida de peso a las 72/96horas y mejor respuesta diurética a las 24horas en comparación con el placebo, sin diferencias significativas según el sexo (ningún valor de p para la interacción fue significativo). El deterioro de la función renal fue más frecuente en mujeres (OR: 8,68; IC95%: 3,41-24,63) que en varones (OR: 2,5; IC95%: 0,99-4,87), p=0,027. No hubo diferencias en la mortalidad ni en los reingresos a los 30/90días. Conclusión La adición de HCTZ a furosemida intravenosa es una estrategia eficaz para mejorar la respuesta diurética en la ICA sin diferencias según el sexo. Sin embargo, el deterioro de la función renal es más frecuente en las mujeres. (AU)

Aims The addition of hydrochlorothiazide (HCTZ) to furosemide improved the diuretic response in patients with acute heart failure (AHF) in the CLOROTIC trial. Our aim was to evaluate if there were differences in clinical characteristics and outcomes according to sex. Methods This is a post hoc analysis of the CLOROTIC trial, including 230 patients with AHF randomized to receive HCTZ or placebo in addition to an intravenous furosemide regimen. The primary and secondary outcomes included changes in weight and patient-reported dyspnoea 72 and 96h after randomization, metrics of diuretic response and mortality/rehospitalizations at 30 and 90days. The influence of sex on primary, secondary and safety outcomes was evaluated. Results One hundred and eleven (48%) women were included in the study. Women were older and had higher values of left ventricular ejection fraction. Men had more ischemic cardiomyopathy and chronic obstructive pulmonary disease and higher values of natriuretic peptides. The addition of HCTZ to furosemide was associated to a greatest weight loss at 72/96h, better metrics of diuretic response and higher 24-h diuresis compared to placebo without significant differences according to sex (all P-values for interaction were not significant). Worsening renal function occurred more frequently in women (OR: 8.68; 95%CI: 3.41-24.63) than men (OR: 2.5; 95%CI: 0.99-4.87), P=.027. There were no differences in mortality or rehospitalizations at 30/90days. Conclusion Adding HCTZ to intravenous furosemide is an effective strategy to improve diuretic response in AHF with no difference according to sex, but worsening renal function was more frequent in women.

Utilidad pronóstica de la presión de pulso en pacientes con insuficiencia cardiaca con fracción de eyección preservada: Registro RICA / Prognostic utility of pulse pressure in patients with heart failure with preserved ejection fraction: The RICA Registry

Background and aims The prognostic role of pulse pressure (PP) in heart failure (HF) patients with preserved left ventricular ejection fraction (LVEF) is not well understood. Our aim was to evaluate it in acute and stable HF. Material and methods This work is a retrospective observational study of patients included in the RICA registry between 2008 and 2021. Blood pressure was collected on admission (decompensation) and 3 months later on an outpatient basis (stability). Patients were categorized according to whether the PP was greater or less than 50mmHg. All-cause mortality was assessed at 1year after admission. Results A total of 2291 patients were included, with mean age 80.1±7.7 years. 62.9% were women and 16.7% had a history of coronary heart disease. In the acute phase, there was no difference in mortality according to PP values, but in the stable phase PP<50mmHg was independently associated with all-cause mortality at 1-year follow-up (HR 1.57, 95% CI 1.21−2.05, p=0.001), after adjusting for age, sex, New York Heart Association functional class, previous HF, chronic kidney disease, valvular heart disease, cerebrovascular disease, score on the Barthel and Pfeiffer scales, hemoglobin and sodium levels. Conclusion Low stable-phase PP was associated with increased all-cause mortality in HF patients with preserved LVEF. However, PP was not useful as a prognostic marker of mortality in acute HF. Further studies are needed to assess the relationship of this variable with mortality in HF patients (AU)

Antecedentes y objetivo El papel pronóstico de la presión de pulso (PP) en pacientes con insuficiencia cardiaca (IC) con fracción de eyección de ventrículo izquierdo (FEVI) preservada no es bien conocido. Nuestro objetivo fue evaluarlo en fases de descompensación y de estabilidad. Material y métodos Estudio observacional retrospectivo de pacientes incluidos en registro RICA entre 2008 y 2021. La presión arterial se recogió al ingreso (descompensación) y a los 3 meses (estabilidad). Se calculó la PP y los pacientes se categorizaron según PP mayor/igual vs menor de 50mmHg. Se evaluó la mortalidad por todas las causas al año del ingreso. Resultados Se incluyeron 2.291 pacientes, con edad media 80,1±7,7 años. El 62,9% eran mujeres y un 16,7% tenían antecedentes de cardiopatía isquémica. En fase aguda, no hubo diferencias en la mortalidad según los valores de PP, pero en fase estable una PP<50mmHg se asoció de forma independiente con mortalidad por todas las causas al año de seguimiento (HR 1,57, IC 95% 1,21-2,05; p=0,001), una vez controlado por edad, sexo, NYHA, IC previa, enfermedad renal crónica, valvulopatía, enfermedad cerebrovascular, Barthel, Pfeiffer, hemoglobina y sodio. Conclusione Una PP baja en fase estable se asoció con mayor mortalidad por todas las causas en pacientes con IC con FEVI preservada. Sin embargo, la PP no demostró ser un factor pronóstico en fase de descompensación. Se necesitan más estudios que valoren la relación de esta variable con la mortalidad en los pacientes con IC (AU)

Valor pronóstico a corto plazo de la proteína C reactiva en ancianos con insuficiencia cardíaca aguda / The short-term prognostic value of C-reactive protein in elderly patients with acute heart failure

Introducción y objetivos: la proteína C reactiva (PCR) plasmática ha sido evaluada como marcador pronóstico en insuficiencia cardíaca aguda (ICA). Sin embargo, no está confirmado que posea validez pronóstica cuando la población de ICA analizada está constituida por pacientes de edad avanzada. Métodos: analizamos los valores plasmáticos de PCR en todos los pacientes ingresados en servicios de medicina interna por ICA de cualquier tipo. Evaluamos la asociación existente entre dichos valores, las características clínicas basales de los pacientes y las tasas de mortalidad y reingreso por cualquier causa a los 3 meses del alta. Para las comparaciones se estratificó a los pacientes en terciles de valor de PCR bajo, medio y alto (< 2,24mg/l, 2,25-11,8mg/l y>11,8mg/l, respectivamente). Resultados: se incluyó a 1.443 pacientes, con una mediana de edad de 80 años (rango intercuartílico 73-85); de ellos, 680 (47%) eran hombres, con una carga de comorbilidad moderada; el 60,1% presentaba fracción de eyección del ventrículo izquierdo preservada (> 50%). El análisis multivariante confirmó la existencia de una asociación independiente entre valores elevados de PCR al ingreso y la presencia de infección respiratoria, presión sistólica baja y función renal alterada. Tres meses después del ingreso índice, un total de 142 pacientes (9,8%) habían fallecido y 268 (18,6%) habían reingresado o habían muerto. Los valores de la PCR en el momento del ingreso no se correlacionaron con la tasa de mortalidad por cualquier causa a los 3 meses (p=0,79), ni con la tasa a los 3 meses de reingreso por cualquier causa (p=0,96) o con la combinación de ambos acontecimientos (p=0,96). Sin embargo, los valores altos de la PCR se asociaron a estancias hospitalarias más prolongadas (p<0,001). Conclusión: nuestro estudio no confirma la existencia de una asociación entre los valores de PCR plasmáticos presentes en el ingreso en los ancianos con ICA con un mayor riesgo de mortalidad o reingreso a los 3 meses

Introduction and objectives: plasma c-reactive protein (crp) has been tested as a prognostic marker in acute heart failure (ahf). Whether its measurement really provides significant prognostic information when applied to elderly patients with ahf episodes remains unclear. Methods: we measured the plasma crp values of patients admitted because of any type of ahf to internal medicine services. We evaluated the association of these values with the patients' baseline clinical characteristics and their 3-month posdischarge all-cause mortality or readmission rates. For comparison purposes, we divided the sample in tertiles of low, medium and high crp values (<2,24mg/l, 2,25-11,8mg/l and>11,8mg/l). Results: we included 1443 patients with a median age of 80 years (interquartile range 73-85); 680 (47%) were men, with a moderate comorbid burden. 60.1% had preserved left ventricular ejection fraction (> 50%). Multivariate analysis confirmed an independent association between higher crp values and the presence of respiratory infection, lower systolic blood pressure and deteriorated renal function upon admission. Three months after the index admission, a total of 142 patients (9.8%) had died, and 268 (18.6%) had either been readmitted or died. admission crp values did not correlate with 3-month all-cause mortality (P=0.79), 3-month all-cause readmission (P=0.96) or the combination of both events (P=0.96). However, higher crp values were associated with a longer length of stay (P<0.001). Conclusion: our study does not confirm an association between admission plasma crp values in elderly ahf patients and subsequent higher 3-month mortality or readmission risks

Impact of prealbumin on mortality and hospital readmission in patients with acute heart failure.

BACKGROUND: Prealbumin is a maker of nutritional status and inflammation of potential prognostic value in acute heart failure (HF). The aim of this study is to evaluate if low prealbumin levels on admission predict mortality and readmissions in patients with acute HF. METHOD: We conducted a prospective observational cohort study including 442 patients hospitalized for acute HF. Patients were classified in two groups according to prealbumin levels: "normal" prealbumin (>15mg) and "low" prealbumin (≤15mg/dL). End-points were mortality and readmissions (all-cause and HF-related) and the combined end-point of mortality/readmission at 180days. RESULTS: Out of 442 patients, 159 (36%) had low and 283 (64%) had normal prealbumin levels Mean age was 79.6 (73.9-84.2, p=0,405) years and 183 (41%, p=0,482) were males. After a median 180days of follow-up, 108 (24%, p=0,021) patients died and 170 (38%, p=0,067) were readmitted. Mortality was higher in the low prealbumin group. The combined end-point was more frequent in the low prealbumin group (57% vs. 50%, p=0.199). In the multivariate analysis the following variables were associated with mortality or readmission: older age, exacerbated chronic HF, higher comorbidity, low systolic blood pressure and hemoglobin values and higher pro brain natriuretic peptide levels. CONCLUSIONS: Low prealbumin is common (36%) in patients with acute heart failure and it is associated with a higher short-term mortality.
