Relación entre la distancia recorrida en el test de caminata, la disnea y la calidad de vida en pacientes con EPOC.

Chronic Obstructive Pulmonary Disease (COPD) is characterized by various signs and symptoms that limit the performance of activities of daily life and affect aerobic capacity, and could also influence healthrelated quality of life (HRQoL). The objective of the present study was to determine the relationship between aerobic capacity, dyspnea and quality of life in COPD patients who attend a pulmonary rehabilitation (PR) program. Descriptive study, with a cross-sectional correlational design in patients with COPD; with the ability to perform the six-minute walk test (6MWT) and answer the SGRQ and CRQ-SAS quality of life questionnaires. 36 patients, mean age 71.9 ± 7.1; mostly men with 83.3%. When correlating the 6MT and dyspnea, mMRC p-value = 0.00 and r = -0.586. In turn, a p-value <0.05 was obtained in the CRQ questionnaire; emotional, fatigue and total domains. The distance traveled on the (6MT) and dyspnea correlate with HRQL in the fatigue, choking and emotional domains of the CRQ questionnaire. No correlations were presented for the SGRQ questionnaire; however, the activities domain has a higher score. In conclusion, the domains of the CRQ questionnaire show a better correlation with the aerobic capacity of patients with COPD. [ABSTRACT FROM AUTHOR]
