Anxiety, Atrial Fibrillation
Conditions
Brief summary
This is an investigation of a mindfulness and interoceptive exposure intervention in patients with atrial fibrillation, to decrease anxiety sensitivity, symptom burden, and atrial fibrillation recurrence.
Detailed description
Patients with atrial fibrillation (AF) have a poorer quality of life and have elevated rates of anxiety. Higher anxiety and somatization has been associated with more severe AF symptoms. Increased anxiety symptoms have also been associated with increased medical visits for AF management. Some studies show that anxiety may increase the risk of AF recurrence following medical intervention, including increasing AF recurrence after circumferential pulmonary vein ablation. Growing evidence suggests a pressing need to treat anxiety and improve quality of life among AF patients, yet few data exist about how to accomplish this. Mindfulness-based behavioral treatments offer promise in this regard. Interoceptive Exposure (IE) is an evidence-based cognitive behavioral intervention to address intolerance of anxiety-related physical sensations, commonly seen in panic disorder and other anxiety disorders. It involves systematically and repeatedly inducing feared physical sensations to promote increased tolerance and reduced distress associated with these symptoms. Mindfulness is defined as paying attention to the present moment in an open and nonjudgmental way. Mindfulness-based behavioral interventions have been successfully applied in various psychiatric and medical patient populations, including cardiac patients. Two meta-analyses suggest that mindfulness-based interventions are moderately effective for reducing distress related to physical or psychosomatic illnesses. The investigators of this study hypothesize that a mindfulness and IE intervention will decrease anxiety, AF symptoms and AF recurrence, and will improve quality of life among patients with AF. This is a pilot, prospective trial of a mindfulness and IE intervention in patients with AF. The mindfulness and IE intervention will be delivered in four to five, manualized, individual sessions.
Interventions
BEHAVIORALMindfulness and Interoceptive Exposure
The Mindfulness and Interoceptive Exposure intervention will be delivered in 4-5 manualized, individualized therapy sessions, of 1.5 hours - 2 hours each. The intervention is comprised of four established cognitive-behavioral strategies: psychoeducation, mindfulness, interoceptive exposure and skills generalization.
