Utilization of Mental Health Care, Treatment Patterns, and Course of Psychosocial Functioning in Northern German Coronary Artery Disease Patients with Depressive and/or Anxiety Disorders

Quality of health care for patients with coronary heart disease and comorbid mental disorders: a prospective cohort study

BACKGROUND

Coronary heart disease (CHD) is often associated with mental disorders (MDs). Comorbid MDs reduce the quality of life and increase cardiac morbidity and mortality. Nevertheless, there is little and inconsistent research on the management of MDs in CHD patients. To bridge this gap, this study aims to gain insight into the long-term course of MD-related health care for patients with CHD, in order to identify opportunities for care improvement.

METHODS

In this prospective cohort study, we investigated whether CHD patients with or without expert-rated MD at baseline (N = 364) received different MD-related health care from either their general practitioner (GP) or cardiologist at follow-up, M = 2.7 [2.0-4.0] years later. In the follow-up assessment, N = 131 CHD patients participated and received questionnaires capturing sociodemographic, mental health, and MD-related health care characteristics. Descriptive statistics, t-tests and chi-squared tests were used for analyses.

RESULTS

We found significant differences in MD-related health care. CHD patients with MD were more likely to be examined psychologically/psychiatrically (MD 55.9%, non-MD 16.7%, p = < .001) and diagnosed with MD (MD 55.9%, non-MD 13.5%, p = .020) by their GP or cardiologist. Recommendations for and responses to requests for psychotherapy were more likely in MD patients compared to non-MD patients (MD 38.7%, non-MD 11.8%, p = .012 and MD 38.5%, non-MD 11.8%, p = .031, respectively). No significant differences were found concerning physicians' active demand for patients' mental health, referral to a specialist for additional diagnostics, provision of information about the diagnosed MD and further treatment options, response to the patients' request for psychopharmacotherapy, help received in finding psychotherapy or psychopharmacotherapy, and actual receipt of these treatments.

CONCLUSIONS

The results indicate differences in MD-related health care of CHD patients with and without comorbid MD. However, they still highlight the need to further encourage primary care physicians treating CHD to adequately address MDs, provide further diagnostics, support, and information to affected patients. To address this, physicians may benefit from awareness training on the association between CHD and MDs and on appropriate communication with MD patients.

Depression and coronary heart disease: mechanisms, interventions, and treatments

Coronary heart disease (CHD), a cardiovascular condition that poses a significant threat to human health and life, has imposed a substantial economic burden on the world. However, in contrast to conventional risk factors, depression emerges as a novel and independent risk factor for CHD. This condition impacts the onset and progression of CHD and elevates the risk of adverse cardiovascular prognostic events in those already affected by CHD. As a result, depression has garnered increasing global attention. Despite this growing awareness, the specific mechanisms through which depression contributes to the development of CHD remain unclear. Existing research suggests that depression primarily influences the inflammatory response, Hypothalamic-pituitary-adrenocortical axis (HPA) and Autonomic Nervous System (ANS) dysfunction, platelet activation, endothelial dysfunction, lipid metabolism disorders, and genetics, all of which play pivotal roles in CHD development. Furthermore, the effectiveness and safety of antidepressant treatment in CHD patients with comorbid depression and its potential impact on the prognosis of CHD patients have become subjects of controversy. Further investigation is warranted to address these unresolved questions.

Claims data analysis of the health care utilization for patients with coronary heart disease and mental comorbidity

OBJECTIVE

Mental disorders (MD) are a common comorbidity in patients with coronary heart disease (CHD) and have a significant impact on morbidity and mortality. The aim of this study was to determine to what extent mental disorders are diagnosed as comorbidity in patients with CHD and whether adequate therapeutic measures are taken.

METHODS

Claims data from 4435 Cologne citizens with diagnosed CHD and a hospital stay due to CHD in 2015 were examined through a longitudinal analysis. The data were analyzed descriptively with regard to mental disorders, investigating diagnostic examinations performed, prescriptions for psychotropic drugs, and utilization of psychotherapy. We differentiated between pre-existing MD, existing in the year before the CHD-related hospital stay, and incident MD with new onset during or within six months after hospitalization.

RESULTS

Psychodiagnostic examinations for mental disorders occurred very rarely during cardiological hospitalization (0.04%) and psychiatric/psychosomatic consultation sessions rarely (5%). The longitudinal analysis showed a high rate of pre-existing MDs (56%, n = 2490) and a new diagnosis of mental disorders in 7% (n = 302) of the patients. Within one year after inpatient treatment for CHD, psychotropic medication was prescribed in 64-67% of patients with newly diagnosed affective or neurotic, adjustment/somatoform disorder and 10-13% received outpatient psychotherapy.

CONCLUSION

The results indicate low rates of inpatient diagnostic examinations and low rates of adequate treatment of mental disorders in patients from Cologne with CHD and new onset mental disorders. The rate of prescriptions of psychopharmacotherapy after hospitalization due to CHD exceeds that of the utilization of outpatient psychotherapy.
