Prevalence of Symptoms of Anxiety Disorders and Depression in Cardiac Rehabilitation Patients in an Academic Hospital: a Case Study.

The relationship between body and mind is increasingly recognized in the occurrence and prognosis of cardiac disease. Based on reports detailing the potential (and the influence of certain risk factors) of developing depression and anxiety following cardiovascular disease, or a cardiac event, most notably acute coronary syndrome (ACS), we investigated whether such symptoms also existed in patient cases found at the cardiac rehabilitation unit of an academic hospital of Eastern Ontario. We examined data from charts during a 6-year period (2012-2017). The Hospital Anxiety and Depression Scale cumulated data within a retrospective cross-sectional study, was used to estimate the prevalence of anxious and depressive symptoms that might reflect the presence of psychological distress. Overall, our sample included 1178 patient files, 81.3% of which were diagnosed with ACS and 69.6% were male. 63.1% of the patients were between 60 and 79 years old at the time of diagnosis. Most patients were Caucasian (81.1%), married (60.3%), and living with their family (74.3%), and 49.7% were recorded as overweight or obese. We found that 29.3% of patients reported symptoms of psychological distress. Regression analyses revealed strong negative correlations between the proportion of symptoms of psychological distress and factors like age and functional capacity as measured by metabolic equivalents. Significant associations were also established between symptoms of psychological distress and factors such as obesity, sedentary lifestyle, smoking, and sex (female). This study was undertaken as part of a business case to implement a new cardiac rehabilitation programme in an academic hospital of Eastern Ontario and illustrate to the managers and decision-makers, the important factors to consider and to target when developing a stepped-care program for patients in cardiac rehabilitation in order to prevent psychological distress and how such a program was relevant to their institution.

Traumatic Stress, Attachment Style, and Health Outcomes in Cardiac Rehabilitation Patients.

OBJECTIVE: Research on psychosocial risk factors in cardiovascular disease (CVD) has identified traumatic stress and attachment style as independent risk factors for the development of CVD and poor prognosis for those with established CVD. Exploring the interrelationships between these variables will inform psychosocial risk factor modeling and potential avenues for intervention. Therefore, the hypothesis that attachment style is related to health outcomes among CR patients and that traumatic stress mediates this relationship was tested. METHODS: Patients in a cardiac rehabilitation program (n = 201) completed validated self-report measures of traumatic stress and attachment style at baseline (program intake). Health outcomes were assessed at baseline and 3 months, including anxiety, depression, quality of life, fasting blood glucose, glycated hemoglobin (HbA1c), and cholesterol (HDL ratio). Multivariate structural equation modeling was used to fit the data. RESULTS: Of the 201 participants, 42 (21%) had trauma scores indicating the probable presence of posttraumatic stress disorder. Via greater levels of traumatic stress, greater attachment anxiety at baseline was indirectly related to greater anxiety, depression, fasting blood glucose, and HbA1c, and poorer physical and mental quality of life. There were no significant indirect effects on HDL ratios. CONCLUSION: Greater attachment anxiety predicted greater traumatic stress; this, in turn, predicted poorer health outcomes. Screening and treatment for these constructs in CVD patients is warranted.

Post-Traumatic Stress Disorder among Cardiac Patients: Prevalence, Risk Factors, and Considerations for Assessment and Treatment.

There is increasing awareness of the impact of post-traumatic stress disorder (PTSD) on physical health, particularly cardiovascular disease. We review the literature on the role of trauma in the development of cardiovascular risk factors and disease, aftermath of a cardiac event, and risk for recurrence in cardiac patients. We explore possible mechanisms to explain these relationships, as well as appropriate assessment and treatment strategies for this population. Our main conclusion is that screening and referral for appropriate treatments are important given the high prevalence rates of PTSD in cardiac populations and the associated impact on morbidity and mortality.
