| Abstract: | Psychosocial risks are significant in the management of patients with cardiovascular disease and implantable cardioverter defibrillators (ICDs). This randomized, controlled, clinical study evaluated the efficacy of adapted yoga (vs. usual care) in reducing psychosocial risks (e.g. anxiety and depression symptoms) and to improve the quality of life in ICD recipients. Forty four participants were administered nine validated measures on psychosocial risk factors, such as shock anxiety, at week one and week eight of the eight-week intervention. The patients in the intervention group participated in a weekly adapted yoga class for eighty minutes for eight weeks with assigned home practices. Clinical measures were collected during the study and at a six-month follow-up. Between-group analyses using pre- and post-treatment reports indicated that the yoga group experienced a decrease in overall shock anxiety, while the control group experienced an increase; the yoga group reduced their specific shock anxiety related to living with the device and increased their overall self compassion and mindfulness (equanimity) regarding emotions, whereas the control group increased their specific shock anxiety and decreased their overall self compassion and mindfulness. Exploratory analyses utilizing a linear model of the observed antitachycardia pacing (ATP) events revealed the expected number of ATP events in the yoga group to be significantly lower than the control group. Additionally, the expected number of ATP events increased more rapidly as a function of the initial ATP events for the control group than it did for the intervention group. This study demonstrated robust psychological benefits from a program of adapted yoga compared to usual care for ICD recipients who are at risk for developing elevated levels of psychological stress accompanied by increased risk for morbidity and mortality. Marked improvements were reported in total shock anxiety, self-compassion, sense of equanimity, and decreased likelihood of ATPs. The findings support the continuation of research in mind-body interventions to better understand the role of complementary medicine to address ICD-specific psychosocial stress and its contributory role in cardiovascular outcomes.
