Consumo máximo de oxígeno durante la prueba de marcha de 6 minutos en la enfermedad pulmonar intersticial difusa y en la hipertensión pulmonar

Abstract

Resumen Introduccion La prueba de marcha de 6 minutos (PM6M) es ampliamente utilizada en la evaluacion de la enfermedad pulmonar intersticial difusa (EPID) y en la hipertension pulmonar (HP). Sin embargo, sus determinantes fisiologicos no han sido bien caracterizados. Objetivo Evaluar los cambios fisiologicos que ocurren durante la PM6M en la EPID y en la HP y compararlos con la prueba de esfuerzo cardiopulmonar (PECP). Material y metodos Se estudiaron 13 pacientes con EPID y 14 con HP mediante PM6M y PECP en cicloergometro. Durante la PM6M se registraron las variables respiratorias mediante telemetria. Resultados El consumo de oxigeno (VO2), la ventilacion y la frecuencia cardiaca mostraron una meseta desde el minuto 3 de la PM6M en ambas patologias. El valor de VO2 no difirio del valor pico en la PECP (14±2 y 15±2 ml/kg/min, respectivamente, en la EPID; 16±6 y 16±6 ml/kg/min, en la HP). En ambas patologias, disminuyo la saturacion arterial de oxigeno, aunque mas marcadamente en la EPID (−12±5%, p Conclusiones En la EPID y en la HP la PM6M se comporta como una prueba de esfuerzo maxima, con valores de VO2 similares a la PECP, poniendo de manifiesto limitacion de la capacidad de transporte de oxigeno. La monitorizacion mediante telemetria durante la PM6M puede ser util para la evaluacion clinica de los pacientes con EPID o con HP.
