Spontaneous coronary artery dissection (SCAD) is an increasingly recognized cause of myocardial infarction; however, the role of cardiac rehabilitation (CR) for patients with SCAD has not been well defined. To further understand CR in patients with SCAD, we studied a large cohort of patients with confirmed SCAD enrolled in the Mayo Clinic SCAD Registry from January 2010 to December 2014 (n = 354). Demographics, clinical characteristics, mental health status, and details about CR participation and experience were collected through medical record review and questionnaires. Participants at time of SCAD were 46 ± 10 years old; 96% were women. Most (76%) attended ≥1 CR sessions, averaging 18 ± 12 sessions. Most reported CR-related physical and emotional benefits (82% and 75%, respectively). Of the CR nonparticipants, 57 of 85 reported not participating because CR was not recommended by their health care provider. Other reasons included inadequate transportation (10 of 85), no insurance coverage (7 of 85), cost (2 of 85), no energy (2 of 85), being too ill (2 of 85), and miscellaneous comments (5 of 85). In conclusion, 3 of 4 of patients with SCAD participated in CR, most of whom reported benefit. Lack of recommendation for CR by a health care provider was the primary reason patients did not participate.
