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

Diferencias en función del sexo en el perfil clínico y pronóstico de pacientes con insuficiencia cardiaca. Resultados del Registro RICA / Gender related differences in clinical profile and outcome of patients with heart failure. Results of the RICA Registry

Antecedentes y objetivos. Analizar las características clínicas diferenciales en función del sexo en pacientes con insuficiencia cardiaca (IC) en cuanto a etiología, comorbilidad, desencadenantes, tratamiento, estancia hospitalaria y mortalidad global al año. Pacientes y método. Se utilizaron los datos del registro RICA, cohorte prospectiva multicéntrica de pacientes hospitalizados en servicios de Medicina Interna por IC con seguimiento de un año. Se analizaron las diferencias de género en cuanto a la etiología de la cardiopatía, comorbilidad, factor desencadenante, fracción de eyección de ventrículo izquierdo, situación funcional, estado mental, tratamiento, estancia y mortalidad al año. Resultados. Se incluyeron 1772 pacientes (47,2% varones). Las mujeres eran mayores que los varones (p<0,001), tenían mayor prevalencia de hipertensión, obesidad, enfermedad renal crónica, fibrilación auricular y fracción de eyección de ventrículo izquierdo preservada (p<0,001). Entre los varones predominaban los antecedentes de infarto de miocardio, enfermedad pulmonar obstructiva crónica, arteriopatía periférica (p<0,001) y anemia (p=0,02). En las mujeres predominó la etiología hipertensiva, seguida de la valvular. Los principales desencadenantes fueron la hipertensión y fibrilación auricular. El tratamiento con beta-bloqueantes, IECA y/o ARA II no difirió en función del sexo. Las mujeres tenían peor capacidad funcional (p<0,001) según el índice de Barthel. Tras ajustar por edad y otros factores pronósticos, la mortalidad al año fue menor entre las mujeres RR:0,69 (IC 95% 0,53-0,89; p=0,004). Conclusiones. La IC en la mujer se presenta a edad más avanzada y con diferente comorbilidad. Predomina la etiología hipertensiva y valvular, con fracción de eyección de ventrículo izquierdo preservada, y la mortalidad ajustada por la edad es menor que en el varón (AU)

History and objectives: To analyze the differential clinical characteristics according to gender of patients with heart failure in terms of etiology, comorbidity, triggers, treatment, hospital stay and overall mortality at one year. Patients and method: We employed data from the RICA registry, a multicenter prospective cohort of patients hospitalized in internal medicine departments for heart failure, with a follow up of one year. We analyzed the differences between the gender in terms of the etiology of the heart disease, comorbidity, triggers, left ventricle ejection fraction, functional state, mental condition, treatment, length of stay and mortality at 1 year. Results: A total of 1772 patients (47.2% men) were included. The women were older than the men (p<.001) and had a higher prevalence of hypertension, obesity, chronic kidney disease, atrial fibrillation and preserved left ventricle ejection fraction (p<.001). The men’s medical history had a predominance of myocardial infarction, chronic obstructive pulmonary disease, peripheral arteriopathy (p<.001) and anemia (p=.02). In the women, a hypertensive etiology was predominant, followed by valvular. The main triggers were hypertension and atrial fibrillation. Treatment with beta-blockers, ACEIs and/or ARBs did not differ by sex. The women had poorer functional capacity (p<.001), according to the Barthel index. After adjusting for age and other prognostic factors, the mortality at one year was lower among the women (RR: 0.69; 95% CI 0.53-0.89; p=.004). Conclusions: HF in women occurs at a later age and with different comorbidities. The hypertensive and valvular etiology is predominant, with preserved left ventricle ejection fraction, and the age-adjusted mortality is lower than in men (AU)
