ABSTRACT
Objetivo Medir e identificar las dimensiones y los determinantes de la calidad de vida relacionada con la salud (CVRS) en los enfermos con insuficiencia cardiaca crónica. Métodos Mediante un estudio transversal se midió la CVRS con los cuestionarios SF-36 y MLHFQ, en 544 enfermos con insuficiencia cardiaca crónica, clínicamente estables, de 97 médicos de atención primaria. Resultados La edad media de los enfermos es de 77,6 años (desviación estándar: 9,9), significativamente mayor en las mujeres. El 31,2% están en grado III-IV de la New York Heart Association (NYHA). El 88,6% tiene al menos otra enfermedad crónica. Las dimensiones físicas tienen peor puntuación que las emocionales en ambos cuestionarios. Tras ajustar por regresión múltiple, siete variables entran en alguno de los cinco modelos y explican entre un 22% y un 36% de la varianza. Conclusiones La CVRS en los pacientes con insuficiencia cardiaca crónica está alterada en todos los dominios. Ser mujer, estar en clase funcional de la NYHA III-IV, la presencia de otras afecciones tales como depresión o enfermedad osteoarticular, el ingreso hospitalario, el índice de masa corporal y la edad, se asocian con una peor percepción de la CVRS (AU)
Objective To measure and identify the dimensions and determinants of health-related quality of life (HRQoL) in patients with chronic heart failure. Methods We performed a cross-sectional study, in which HRQoL was measured with the short-form (SF)-36 and the Minnesota Living with Heart Failure Questionnaire (MLHFQ) in 544 clinically-stable patients with chronic heart failure managed by 97 primary care physicians. Results The mean age of the patients was 77.6 years (SD: 9.9) and was significantly higher in women. A total of 31.2% were in New York Heart Association (NYHA) grade III-IV and 88.6% had at least one chronic condition. In both questionnaires, physical dimensions scored worse than emotional dimensions. After adjustment was made for multiple regression, seven variables entered into one of the five models and explained between 22% and 36% of the variance. Conclusions HRQoL in patients with chronic heart failure is impaired across all domains. Being female and being in NYHA functional class III-IV, as well as other factors such as depression, osteoarticular disease, hospital admission, body mass index and age, were associated with poorer self-perceived HRQoL (AU)

INTRODUCTION AND OBJECTIVES: To evaluate the applicability, internal consistency and validity of the Minnesota Living with Heart Failure Questionnaire (MLHFQ) when used in primary care, compared with the Short Form-36 (SF-36) health survey. METHODS: The two questionnaires were administered to 589 patients with chronic heart failure who were registered with 97 primary care physicians. The applicability, internal consistency and validity of the MLHFQ were evaluated and comparisons were made with the SF-36. RESULTS: More than 90% of patients completed the questionnaires. The percentage of uncompleted items was low. Cronbach's alpha ranged from 0.79 to 0.94 for the various MLHFQ dimensions. Exploratory factorial analysis identified two factors that explained 65.8% of the variance. Moderate to good correlations were observed between similar dimensions of the MLHFQ and SF-36 (correlation coefficient -0.43 to -0.73). There were significant associations between scores on the MLHFQ and clinical measures of disease severity. CONCLUSIONS: When used in primary care, the MLHFQ had a high level of acceptability and good psychometric properties compared with the SF-36. Consequently, it would be useful for assessing health-related quality of life in patients with chronic heart failure.

Introducción y objetivos. Evaluar la aplicabilidad, la consistencia interna y la validez del Minnesota Living with Heart Failure Questionnaire (MLHFQ) en atención primaria, comparándolo con el Short-Form Health Survey (SF-36). Métodos. Se aplicaron ambos cuestionarios a 589 pacientes con insuficiencia cardiaca crónica documentada atendidos por médicos de atención primaria. Analizamos la factibilidad, la consistencia interna y la validez del MLHFQ comparado con el SF-36. Resultados. Respondió los cuestionarios más del 90% de la muestra. El porcentaje de ítems no respondido es bajo. El coeficiente alfa de Cronbach oscila entre 0,79 y 0,94 para las dimensiones del MLHFQ. Del análisis factorial exploratorio, se extraen dos factores que explican una varianza total del 65,8%. Los coeficientes de correlación entre dimensiones similares del MLHFQ y el SF-36 fueron de moderados a altos (0,43 a 0,73). Las puntuaciones del MLHFQ se asocian significativamente con variables clínicas de gravedad. Conclusiones. En atención primaria el MLHFQ, comparado con el SF-36, muestra buena aceptabilidad y buenas propiedades psicométricas que lo hacen útil para medir la calidad de vida relacionada con la salud en pacientes con insuficiencia cardiaca crónica (AU)
