Arrhythmia, Atrial Fibrillation
Conditions
Brief summary
The aim is to evaluate if internet- delivered CBT, based on behavioral activation and exposure principles, improves wellbeing and QoL in symptomatic AF patients.The study will include 30 patients with symptomatic AF despite optimal medical treatment in accordance with current guidelines.
Detailed description
Atrial fibrillation (AF) is the most common cardiac arrhythmia (irregular heartbeat) affecting 3% of the population. AF is associated with poor quality of life (QoL) and large costs for society. In a considerable proportion of patients, AF symptoms (e.g., palpitations, fatigue, and chest pain) are not alleviated by current medical or interventional treatments. Psychological factors can worsen AF symptoms, and anxiety and depression are common among AF patients. Symptom preoccupation and avoidance of social and physical activities are likely to play important roles in the development of anxiety, depression, disability and healthcare utilization. The aim is to evaluate if CBT, based on behavioral activation and exposure principles, improves wellbeing and QoL in symptomatic AF patients. Method: Pilot study with a pre-post-design and no control group. The internet-delivered CBT-program will last for 10 weeks and include weekly therapist support, consisting of online messages and telephone calls.
Interventions
The CBT treatment lasts for 10 weeks and includes the following: Education on the role of anxiety on cardiac function and the effects of symptom preoccupation and avoidance QoL and depression in AF, creating a vicious cycle; exposure to physical sensations that are similar to AF symptoms (e.g.,palpitations due to physical activity or stress) to reduce fear of these symptoms; exposure to situations or activities previously avoided and abolishment of behaviors that fruitlessly aim to prevent triggering of AF episodes or to control symptoms; and behavioral activation aiming to increase social and physical activity and reduce depressive symptoms. Therapist support is provided at least once weekly through the platform developed for the purpose. Therapists are trained CBT-psychologists.

Design outcomes
Primary
| Measure | Time frame | Description |
|---|---|---|
| Change in The Atrial Fibrillation Quality of Life (AFEQT) | From baseline to 12 weeks | The AFEQT is an atrial fibrillation-specific measure that taps into the QoL-domains: symptoms, daily activities, treatment concern, and treatment satisfaction. |
Secondary
| Measure | Time frame | Description |
|---|---|---|
| Symptom checklist (SCL) | From baseline to 12 weeks. | Change in AF related symptoms: |
| Atrial Fibrillation Severity Scale | From baseline to 12 weeks. | Change in symptomatic burden |
| Cardiac Anxiety Questionnaire | From baseline to 12 weeks. | Change in symptom preoccupation: |
| GAD-7 | From baseline to 12 weeks. | Change in anxiety |
| WHODAS 2.0 (12-item version) • | From baseline to 12 weeks. | Change in general quality of life |
| Perceived stress scale | From baseline to 12 weeks. | Change in stress reactivity |
| Change in healthcare consumption and work loss: TIC-P | From baseline to 12 weeks. | The Trimbos and Institute of Medical Technology Assessment Cost Questionnaire for Psychiatry assesses societal cost during the last month. These costs include the participant's health care consumption (direct medical costs), time spent in other health promoting activities (direct non-medical costs), and sick leave, unemployment, and reduced work capacity at work and in the domestic realm (indirect non-medical costs). |
| Change in symtomatic burden: Holter ECG. | From baseline to 12 weeks. | The patient will undergo a 24 h ECG assessment in order to measure objectively symptomatic burden (number and duration of symptomatic AF episodes and symptomatic non-AF episodes) |
| Change in symptomatic burden: Holter ECG. | From baseline to 9 months. | The patient will undergo a 24 h ECG assessment in order to measure objectively symptomatic burden (number and duration of symptomatic AF episodes and symptomatic non-AF episodes) |
| PHQ-9 | From baseline to 12 weeks. | Change in depression: |
