CARDIOLOGY FOCUS: CARDIAC PSYCHOLOGY
Meeting of Hearts & Minds – The Practice of Cardiac Psychology Written by Jonathan Gallagher, Senior Psycholgist, Beaumont Hospital, Dublin - Dr Elizabeth O'Brien, Senior Clinical Psychologist, St Vincent's University Hospital and Dr Sinead Mulhern, Principal Clinical Levine et al Psychologist, Mater Hospital PSYCHOLOGICAL FACTORS & CARDIOVASCULAR DISEASE (CVD) A cardiac event such as a heart attack can be a psychologically devastating experience, with profound and enduring consequences. Frequently its onset is sudden, distressing and potentially life-threatening. Even if this is not the case, mere knowledge of this new disease status can trigger strong and frequently long-term emotional reactions as well as prompting significant lifestyle changes.

Perhaps unsurprisingly, psychological distress is highly prevalent in patients with cardiovascular disease (CVD). Anxiety, depression and insomnia disorder affect approximately one-third of people with CVD, and up to one in four cardiac patients experience clinically significant levels of posttraumatic stress (PTSD)1-4. Furthermore, psychological distress is linked to increased future cardiac events and mortality, poorer quality of life, increased suicide risk, greater healthcare costs and poorer long-term psychological adjustment5. Unfortunately, there is also evidence that during the COVID-19 pandemic psychological distress has increased in cardiac patients and this has been exacerbated by social isolation, treatment nonadherence, physical inactivity, and an increase in unhealthy lifestyle behaviours6,7. COMMON PSYCHOLOGICAL RESPONSES TO CVD
Dr Sinead Mulhern
In the initial aftermath of a cardiac event, the focus is understandably on the patient’s physical recovery, and many people feel relief or even gratitude for having survived. However, once a person begins to feel better physically, the emotional distress they have been holding at bay can surface. It may feel safer for this to emerge after things appear to have stabilised medically. Although this can be a normal part of the recovery process it can be quite frightening if the person hasn’t experienced this kind of emotional vulnerability previously.
