The aim of this study was to investigate the relationship between arterial stiffness and pulmonary and extrapulmonary features in patients with ankylosing spondylitis.
Diagnosis of ankylosing spondylitis according to ASAS diagnostic criteria
Being aged 18-65
Stable medication use for at least 3 months
Voluntary participation in the study
Having uncontrolled cardiopulmonary disease
Being pregnant
Having undergone recent surgery
Presence of malignancy
Patients followed up with a diagnosis of ankylosing spondylitis will be included.
Case-only
Cross-sectional
Not listed
Arterial stiffness
It will be evaluated with brachial pulse waves.
Respiratory muscle strength
Maximal inspiratory pressure (MIP) and maximal expiratory pressure (MEP) will be measured using a portable mouth pressure device.
Respiratory muscle endurance
This will be evaluated with increased workload testing.
Exercise capacity
Exercise capacity will be assessed with 6 minute walk test.
Physical activity
Physical activity level will be evaluated using International Physical Activity Questionnaire-Short form
Forced vital capacity
Forced vital capacity (FVC) will be assessed using spirometry.
Forced expiratory volume in one second
Forced expiratory volume in one second (FEV1) will be assessed using spirometry.
Forced expiratory volume in one second/forced vital capacity ratio
Forced expiratory volume in one second/forced vital capacity ratio will be assessed using spirometry.
