Abstrakt: | BACKGROUND: Continuous monitoring of ... throughout the 6-min walk test (6MWT) unveiled that some patients with respiratory diseases may present values across the test lower than ... measured at the end of the test. Nevertheless, it remains unclear whether this approach improves the yield of walk-induced desaturation detection in predicting mortality and hospitalizations in patients with COPD. METHODS: Four hundred twenty-one subjects (51% males) with mild2very severe COPD underwent a 6MWT with continuous measurement of .... Exercise desaturation was defined as a fall in ... ≥ 4%. All-cause mortality was assessed up to 6 y of follow-up and the rate of hospitalizations in the year succeeding the 6MWT. RESULTS: One hundred forty-nine subjects (35.4%) died during a mean (interquartile) follow-up of 55.5 (30.2-64.1) months. Desaturation was observed in 299/421 (71.0%). ... along the test was < end ... (88 [82-92]% vs 90 [84293]%, P < .001). Desaturation detected only during (but not at the end of) the test was found in 81/421 (19.2%) participants. Multivariate Cox regression model adjusted for sex, body composition, FEV |
