Spontaneous coronary artery dissection (SCAD) can occur as an atypical cause of myocardial infarction. Preliminary evidence suggests that SCAD patients experience high rates of post-event psychological distress. It is unknown whether psychosocial interventions may reduce the distress burden. Seven SCAD patients (mean age = 53.3 years) completed a CBT-based support group. All seven participants completed measures for anxiety, depression, and cardiac-related quality of life at baseline and post-intervention, and five participants completed measures at 3-month follow-up. Six of 7 participants scored above the clinical threshold on a measure of anxiety at baseline and posttreatment. At follow-up, 3 of 5 participants scored below the clinical threshold. For depression, 3 of 7 reported elevated depressive symptoms at baseline. By follow-up, 1 of 5 endorsed elevated depressive symptoms. This is the first known psychosocial intervention study of patients with SCAD. Anxiety symptoms improved for most patients by follow-up with some patients having improved depressive symptoms. Although the sample size is limited, this pilot study suggests a potential benefit of group psychosocial interventions for SCAD survivors.
