Fear of recurrence and its association with mental health outcomes after spontaneous coronary artery dissection (SCAD)

Abstract Background Spontaneous coronary artery dissection (SCAD) is a rare cause of acute myocardial infarction, predominantly affecting younger women with few traditional cardiac risk factors. The condition is characterised by relatively high rates of recurrence. Recent qualitative studies demonstrate that SCAD survivors often experience fears about the future, particularly relating to SCAD recurrence and death. Research in psycho-oncology demonstrates that experiencing fear of cancer recurrence predicts worse outcomes for mental health and quality of life, an association that is also likely in cardiac patients. To date, no quantitative research has investigated fear of recurrence and its association with mental health in SCAD survivors. Purpose The aim of this study was to investigate the prevalence of fears relating to SCAD recurrence and the association of fear of recurrence with mental health outcomes. Methods 293 SCAD survivors completed an online questionnaire assessing the psychosocial impacts of SCAD. Participants rated whether they experienced these impacts ‘not at all’, ‘a small amount, ‘a moderate amount’ or ‘a large amount’ within the first six months of their SCAD. Items related to fears about the future, recurrence, and death were extracted for analysis. Participants also completed measures of anxiety (Generalised Anxiety Disorder-7), depression (Patient Health Questionnaire-9), distress (Cardiac Distress Inventory - Short Form), and mental health related quality of life (Short Form 12, mental health component). Results In the six months following their SCAD, 97.6% of survivors experienced some level of worry about having another SCAD, 95.6% were concerned about triggering another SCAD, 95.6% experienced fear of the future, and 82.6% experienced fear of dying. Reports of experiencing ‘a large amount’ of fear in these areas were 54.6%, 45.1%, 42.7%, and 30.4% respectively. The amount of worry reported about having another SCAD was significantly associated with increased levels of anxiety, depression, and cardiac distress, and reduced mental health quality of life. Conclusions Almost all SCAD survivors reported fears, worries, and concerns related to recurrence. Worry about SCAD recurrence was significantly associated with important mental health outcomes. Cardiac health professionals should monitor fears of recurrence in their patients, as a large amount of worry may be indicative of poor mental health, and referral to psychology services may be appropriate.Rates of fears of SCAD recurrence
