Summary

Cut-off values indicating reduced functional status in 6-min walk test and 30-second sit-to-stand test in patients with atrial fibrillation will be determined in the study.

Description

The 6-min walk test (6MWT) is the most used field test for measuring functional status in cardiopulmonary patients. However, to be able to objectively interpret 6MWT of a patient with specific chronic condition, the distance walked in 6MWT should be compared to either a healthy control group or a cut-off value that was specifically determined for that population. Such cut-off values are present for 6MWT in several cardiopulmonary diseases including COPD (350 m), heart failure (200 m) and pulmonary hypertension (400 m) for identifying patients with high mortality, poor prognosis and/or poor functional status, but there is no cut-off value determined for atrial fibrillation (AF). New York Heart Association (NYHA) functional classification is another measure that is widely used for classifying the functional status of patients with various cardiac diseases including AF. While NYHA class 1 indicates preserved functional status, NYHA class 2, 3 and 4 indicate the different degrees of reduction in functional status. Primary aim of this study is to determine a cut-off value in 6MWT for discriminating between the AF patients with preserved and reduced functional status according to NYHA functional classification. In addition, a cut-off value for 30-second sit-to-stand test will be determined in these patients as well, since sit-to-stand tests have gained a lot of interest in the recent literature for practically evaluating functional status in various cardiopulmonary conditions.
