Study summary

This study will compare the effectiveness that Cognitive Behavioral Therapy has on decreasing the amount of anxiety, as well as the number of inappropriate firings that a patient with an ICD may experience.

Read the detailed description

This study is an interventional study of patients with ICDs followed in the Cleveland Clinic Device Clinic. Patients with ICDs experience some level of anxiety which can impact the number of shocks that they receive from their Device. 100 of these patients will be randomized into one of 2 groups; those receiving three sessions of Cognitive Behavioral Therapy (CBT) and those receiving usual care. We hypothesize that if these ICD patients receive short term (CBT) they will experience less anxiety and have a lower rate of device firings than the patients that did not receive CBT. Furthermore, we will study mechanistic pathways involved in the reduction of anxiety in ICD patients. We will extract initial heart rate variability (HRV) data from device interrogation. We hypothesize that the CBT intervention arm will have a higher normalization of HRV. Patients will repeat questionnaires at 3, 6 and 12 months.

What researchers measure

Primary outcomes

  1. Patients in the CBT intervention arm will have a higher reduction in anxiety and experience better quality of life compared to usual care at 3 months.

    Time frame: Patients in the CBT arm will have (3) 45min. sessions scheduled over a 3 month period.

Secondary outcomes

  1. Patients in the CBT intervention arm will have a lower rate of firings (shocks).

    Time frame: Patients in both arms will have their ICD's interrogated at 3, 6 and 9 months.
