Seasonal Physical Activity in Patients With Heart Failure With Cardiac Implantable Electronic Devices (CIED)

May 5, 2026 updated by: Gamze Nur AHISKALI, Erol Olcok Corum Training and Research Hospital

The Effect of Seasonal Variation on Physical Activity in Patients With Heart Failure With Cardiac Implantable Electronic Devices

The aim of this observational study is to determine the effect of seasonal changes on physical activity levels in heart failure patients with cardiac implantable electronic devices.

Patients with heart failure who have a cardiac implantable electronic device will be evaluated throughout the year.

Design Details

Cohorts and Interventions

Group / Cohort
Intervention / Treatment
Patients with Heart Failure with Cardiac Implantable Electronic Devices
Seasonal variations in physical activity will be objectively investigated in heart failure patients with implantable cardiac electronic devices.

What is the study measuring?

Primary Outcome Measures

Outcome Measure
Measure Description
Time Frame
Participant's objective physical activity level
Time Frame: Every three months for one year (Patients will be evaluated in all four seasons: spring, summer, autumn, and winter)
Objective measurement of physical activity will be assessed using an accelerometer (Garmin Vivosmart 5). The accelerometer will be placed on the patient's non-dominant wrist for one week, 5 days a week during weekdays and 2 days a week on weekends. The accelerometer can be used day and night, while sleeping or showering, and has enough battery life to collect activity data throughout the day.
Every three months for one year (Patients will be evaluated in all four seasons: spring, summer, autumn, and winter)
Participant's subjective physical activity level
Time Frame: Every three months for one year (Patients will be evaluated in all four seasons: spring, summer, autumn, and winter)
Additionally, physical activity will be assessed using International Pyhsical Activity Questionnaire Short Form (IPAQ). The questionnaire examines physical activity in four different groups: vigorous physical activity, moderate physical activity, walking, and sitting. In the results evaluation, the data is converted to metabolic rate (MET) values and calculated accordingly.
Every three months for one year (Patients will be evaluated in all four seasons: spring, summer, autumn, and winter)

Secondary Outcome Measures

Outcome Measure
Measure Description
Time Frame
Participant's functional capacity
Time Frame: Every three months for one year (Patients will be evaluated in all four seasons: spring, summer, autumn, and winter)
The maximal symptom-limited Cardiopulmonary Exercise Test (CPET), the gold standard method for assessing functional capacity, will be used.
Every three months for one year (Patients will be evaluated in all four seasons: spring, summer, autumn, and winter)
Participant's motivation for physical activity
Time Frame: Every three months for one year (Patients will be evaluated in all four seasons: spring, summer, autumn, and winter)
This 16-item scale includes individual, environmental, and irrational dimensions that influence participation motivation. The total score changes between 16 and 80. Higher scores indicate higher motivation for participating in physical activity.
Every three months for one year (Patients will be evaluated in all four seasons: spring, summer, autumn, and winter)
