Guided Internet-delivered cognitive behavioural therapy in patients with non-cardiac chest pain: -a pilot randomized controlled study

• Background: Patients with recurrent episodes of non-cardiac chest pain (NCCP) suffer from cardiac anxiety as they misinterpret the pain as being cardiac-related and avoid physical activity that they think could threaten their life. This could lead to increased healthcare utilization and costs. These patients might benefit from help and support to evaluate the perception and management of their chest pain. Objective: To test the feasibility of a short guided Internet-delivered cognitive behavioural intervention and the effects on chest pain, cardiac anxiety, fear of body sensations and depressive symptoms in patients with NCCP compared to usual care.Methods: A pilot randomized controlled study was conducted. Fifteen patients, 9 men and 6 women between the age of 22 and 76 (median age of 66 years, q1-q3 57-73) were randomly assigned to either intervention (n=7) or control (n=8) group. Patients had recurrent NCCP and suffered from cardiac anxiety or fear of body sensations. The intervention consisted of a 4-session guided Internet-delivered cognitive behavioural therapy program containing psychoeducation, exposure to physical activity, and relaxation. The control group received usual care. All patients completed a web-based questionnaire on socio-demographic variables, chest pain frequency, cardiac anxiety, fear of body sensations, and depressive symptoms. Results: Five out of the 7 patients in the intervention group completed all sessions as planned and two completed only parts of the program. The program was perceived as user-friendly with comprehensible language, adequate and varied content, and manageable homework assignments. The patients were engaged in the program for about 45-60 minutes per day and about 22 minutes’ therapist time was required to guide, support and give feedback to each patient throughout the program. Participating in the program empowered and motivated many of the patients to be active and complete the program. In general, patients in both the intervention and control groups improved with regard to chest pain frequency, cardiac anxiety, fear of body sensations, and depressive symptoms, but there were no significant differences between the groups. Conclusions: A short guided Internet-delivered cognitive behavioural therapy program was feasible. Patients in both the intervention and control groups improved with regard to chest pain frequency, cardiac anxiety, fear of body sensations, and depressive symptoms, but no significant differences were found between the groups. Patients should be followed-up for longer periods to measure the long-term effects of the intervention.
