Factores epidemiológicos asociados a la hospitalización por descompensación de la insuficiencia cardiaca / Epidemiological events related to decompensated heart failure

Objetivo: El presente estudio pretende conocer el perfil del paciente que ingresa por descompensación de insuficiencia cardíaca en un hospital de tercer nivel asistencial. Métodos: Se diseña un estudio observacional y retrospectivo en el que se registra de forma aleatoria los ingresos por este proceso en nuestro centro durante el año 2005. Resultados: El tamaño muestral es de 209 pacientes (media de edad: 78,6 ± 9,1; 52,4% varones), con un índice de comorbilidades del 87,55%. Casi un tercio de los pacientes no disponen de valoración de la función sistólica y entre los restantes, la gran mayoría (72,4%) presentan función sistólica conservada. La gran mayoría de las descompensaciones surgen en el seno de infecciones respiratorias. La cardiopatía isquémico-hipertensiva es el origen más frecuente de la cardiopatía con disfunción sistólica. Se registró una estancia hospitalaria media de 12,9 días con un índice de mortalidad del 9,56% resultando sus principales factores de riesgo estadíos funcionales avanzados en las escalas de la NYHA o de la Cruz Roja así como la presencia de demencia o ictus. Conclusiones: El presente estudio muestra un perfil del paciente hospitalizado por descompensación de insuficiencia cardíaca que difiere notablemente de aquel incluído en los grandes ensayos clínicos, lo que sin duda dificulta la aplicación de estrategias terapéuticas que han demostrado ser útiles en aquellos casos

Objective: The present study aimed to evaluate the profile of patients with decompensated heart failure hospitalized in a tertiary hospital. Methods: It was designed an observational and retrospective study where data from clinical records of patients suffering from heart failure along 2005 were registered randomly. Results: 209 patients were collected (average age: 78.6 ± 9.1; male:52.4%) with a comorbidity rate of 87.55%. Almost one third of them have not stimation of systolic function and among the others 72.4% have it preserved. Most of decompensated were due to respiratory infections. Ischemic-hipertensive cardiopathy was the most frequent aetiology ofsystolic disfunction. Average stay was 12.9 days with a mortality rate of 9.56%. Its main risk factors were advanced stages in NYHA od Red Cross scales, as so as dementia or ictus. Conclusions: The present study shows a patient hospitalized for decompensated heart failure roughly different from that one reported at clinical trials. It makes difficult to apply therapeutical interventions, previously well documented to be useful
