Abstract
Background

Chronic obstructive pulmonary disease and heart failure (HF) are 2 diseases with high morbidity and mortality. The coexistence of these two diseases is estimated to be frequent, but has been poorly studied.

Aim

To study the prevalence of airflow limitation in a sample of patients diagnosed with HF in follow-up in an HF unit and to assess their characteristics and comorbidities.

Methods

This is a prospective observational study. The patients who visited the HF Unit of the Hospital Universitari Germans Trias i Pujol between January 2014 and June 2015 were included consecutively. Respiratory functional tests were performed and clinical data were obtained.

Results

118 patients were included in the study (age 67.2 years, 77.1% men). The prevalence of non-reversible airflow obstruction was 36.4%, with an underdiagnosis percentage of 67.4%. Patients with airflow limitation had an increase in comorbidities, but no worse prognosis.

Conclusion

The prevalence of airflow limitation in patients with HF is high, with a significant degree of underdiagnosis. It seems reasonable to recommend performing a screening spirometry in these patients.

Resumen
Introducción

La enfermedad pulmonar obstructiva crónica y la insuficiencia cardíaca (IC) son 2 enfermedades con una elevada morbimortalidad. La coexistencia de estas 2 enfermedades se estima que es frecuente, pero ha sido escasamente estudiada.

Objetivo

Estudiar la prevalencia de limitación al flujo aéreo en una muestra de pacientes diagnosticados de IC en seguimiento en una unidad de IC y valorar las características y comorbilidades de estos pacientes.

Métodos

Se trata de un estudio prospectivo observacional. Se incluyeron de forma consecutiva los pacientes visitados en la Unidad de Insuficiencia Cardíaca del Hospital Universitari Germans Trias i Pujol entre enero del 2014 y junio del 2015. Se realizaron pruebas funcionales respiratorias y se obtuvieron datos clínicos.

Resultados

Se incluyeron 118 pacientes en el estudio (edad 67,2 años; DE 12,1; el 77,1% hombres). La prevalencia de limitación al flujo aéreo fue del 36,4%, con un porcentaje de infradiagnóstico del 67,4%. Los pacientes con limitación al flujo aéreo presentaban un aumento de las comorbilidades y de la mortalidad.

Conclusión

La prevalencia de limitación al flujo aéreo en pacientes con IC es elevada, con un importante grado de infradiagnóstico. Sería recomendable la realización de una espirometría de cribado en estos pacientes.
