espanolObjetivo: Conocer la asociacion entre el tiempo de estancia hospitalaria en casos de insuficiencia cardiaca aguda con cuatro indices ecocardiograficos en los pacientes hospitalizados en la Unidad de Cuidados Coronarios del Hospital Guillermo Almenara. Los indices estudiados son la relacion velocidad de onda E por doppler pulsado del flujo mitral/ velocidad de onda e’ por doppler tisular en anillo mitral (E/e’), el diametro de la vena cava inferior, la presion sistolica de la arteria pulmonar y el indice de colapso de la vena cava inferior.Materiales y metodos: Se realizo un estudio cuantitativo, descriptivo, retrospectivo y correlacional con todos los pacientes hospitalizados por insuficiencia cardiaca aguda durante el ano 2015. La asociacion entre el tiempo de estancia hospitalaria y la relacion E/e’, el diametro de vena cava inferior y la presion sistolica de la arteria pulmonar se estudio con la prueba de Pearson. Se empleo odds ratio (OR) para establecer la relacion de la estancia hospitalaria con el indice de colapso de vena cava inferior. Resultados: Se incluyeron 65 pacientes con una media de edad de 67,8 anos y la mayoria era de sexo masculino (61,5 %). La media de la estancia hospitalaria fue 5,83 dias. El diagnostico previo de insuficiencia cardiaca mostro asociacion con una estancia hospitalaria mayor a 5 dias (prueba de la X2). No hubo asociacion entre la fraccion de eyeccion del ventriculo izquierdo y la estancia hospitalaria (OR de 1,016 [IC 95 % = 0,380 - 2,717]). Se encontro asociacion significativa entre el incremento en la relacion E/e’ (p = 0,002), el mayor diametro de vena cava inferior (p = 0,006) y el indice de colapso de vena cava inferior menor a 50 % (p EnglishObjective: To know the association between the length of hospital stay for acute heart failure and four echocardiographic indices among inpatients in the Coronary Care Unit of the Hospital Guillermo Almenara Irigoyen. The study indices were the ratio of mitral valve inflow velocity of pulsed-wave Doppler E and mitral annular tissue velocity of pulsed-wave Doppler e’ (E/e’), inferior vena cava diameter, inferior vena cava collapse rate and pulmonary artery systolic pressure.Materials and methods: A quantitative, descriptive, retrospective and correlational study was conducted with all patients hospitalized for acute heart failure during 2015. The association that the length of hospital stay has with the E/e’ ratio, inferior vena cava diameter and pulmonary artery systolic pressure was analyzed using Pearson’s correlation coefficient. The relationship between the length of hospital stay and the inferior vena cava collapse rate was determined using the OR. Results: The study population consisted of 65 patients whose mean age was 67.8 years and who were mainly males (61.5 %). The mean hospital stay was 5.83 days. The diagnosis of heart failure was associated with a hospital stay greater than 5 days (chi-square test). There was no association between left ventricular ejection fraction and hospital stay (OR = 1.016; 95 % CI = 0.380 – 2.717). A significant association was found between a longer hospital stay and the increase in the E/e’ ratio (p = 0.002), larger inferior vena cava diameters (p = 0.006) and inferior vena cava collapse rates less than 50 % (p
