Study summary

Cut-off values indicating higher symptom burden and impairment in health status in 6-min walk test and 30-second sit-to-stand test in patients with atrial fibrillation will be determined in the study.

Read the detailed description

The 6-min walk test (6MWT) is the most used field test for measuring functional impairment 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 health status, but there is no cut-off value determined for atrial fibrillation (AF). The European Heart Rhythm Association (EHRA) score is a practical measure for assessing symptom burden and functional impairment caused by AF-related symptoms. While EHRA class 1 indicates asymptomatic patients, EHRA class 2, 3 and 4 indicates higher severities of symptom burden and functional impairment. Primary aim of this study is to determine a cut-off value in 6MWT for discriminating between the asymptomatic and symptomatic AF patients according to EHRA 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.

What researchers measure

Primary outcomes

  1. The European Heart Rhythm Association (EHRA) score

    Functional impairment and symptom burden of the patients will be determined according to The European Heart Rhythm Association (EHRA) score. While EHRA class 1 indicates asymptomatic patients, EHRA class 2, 3 and 4 indicates higher severities of symptom burden and functional impairment, respectively.

    Time frame: At baseline

  2. 6-min walk distance

    Distance walked in six minutes will be recorded. Test will be conducted according to the guideline of American Thoracic Society (ATS).

    Time frame: At baseline

  3. Number of repetitions in 30-second sit-to-stand test

    Participants will be asked to perform sit-to-stand maneuver as fast as possible for 30 seconds and the number of completed repetitions will be recorded.

    Time frame: At baseline

Secondary outcomes

  1. Forced Vital Capacity (FVC)

    FVC will be measured using basic spirometry according to the guideline of European Respiratory Society (ERS)

    Time frame: At baseline

  2. Forced Expiratory Volume in 1 second (FEV1)

    FEV1 will be measured using basic spirometry according to the guideline of European Respiratory Society (ERS)

    Time frame: At baseline

  3. Peak Expiratory Flow (PEF)

    PEF will be measured using basic spirometry according to the guideline of European Respiratory Society (ERS)

    Time frame: At baseline

  4. Maximum inspiratory pressure (MIP)

    MIP will be measured using electronic mouth pressure meter according to the guideline of European Respiratory Society (ERS)

    Time frame: At baseline

  5. Maximum expiratory pressure (MEP)

    MEP will be measured using electronic mouth pressure meter according to the guideline of European Respiratory Society (ERS)

    Time frame: At baseline

  6. Short Form-36

    Short Form-36 questionnaire will be used to measure quality of life.

    Time frame: At baseline

  7. International Physical Activity Questionnaire - Short Form

    International Physical Activity Questionnaire - Short Form will be used to measure physical activity level

    Time frame: At baseline
