The First Dedicated Cardiac Rehabilitation Program for Patients With Spontaneous Coronary Artery Dissection: Description and Initial Results

Abstract Background Spontaneous coronary artery dissection (SCAD) is an important cause of myocardial infarction in women, but the role of rehabilitation after SCAD is unclear. Methods We designed a dedicated SCAD cardiac rehabilitation (SCAD-CR) program for our SCAD survivors at Vancouver General Hospital. This program encompasses a multidisciplinary approach including exercise rehabilitation, psychosocial counselling, dietary and cardiovascular disease education, and peer group support. Exercise and educational classes were scheduled weekly with a targeted participation of 6 months. Psychosocial counselling, mindful living sessions, social worker and psychiatry evaluations, and peer-group support were offered. Results We report our first consecutive cohort of 70 SCAD women who joined SCAD-CR from November 2011 to April 2015. The average age was 52.3 ± 8.4 years. Mean participation duration was 12.4 ± 10.5 weeks; 28 completed 6 months, 48 completed ≥ 1 month. At entry, 44 (62.9%) had recurrent chest pains and average metabolic equivalents on exercise treadmill test was 10.1 ± 3.3. At program exit, the proportion with recurrent chest pains was lower (37.1%) and average metabolic equivalents was higher 11.5 ± 3.5 (both P P  = 0.046). Twenty (28.6%) social worker referrals and 19 (27.1%) psychiatry referrals were made. Mean follow-up was 3.8 ± 2.9 years from the presenting SCAD event, and the major cardiac adverse event rate was 4.3%, lower than our non-SCAD-CR cohort (n = 145; 26.2%; P Conclusions This is the first dedicated SCAD-CR program to address the unique exercise and psychosocial needs of SCAD survivors. Our program appears safe and beneficial in improving chest pain, exercise capacity, psychosocial well-being and cardiovascular events.
