Comorbidity of depression and anxiety leads to a poor prognosis following angina pectoris patients: a prospective study

BACKGROUND

Depression and anxiety are two common mood problems among patients with cardiovascular disease (CVD) and are associated with poor cardiac prognoses. The comorbidity of depression and anxiety is considered to be a more severe psychological status than non-comorbid mood disorders. However, little is known about the relationship between depression or anxiety and noncardiac readmission. We conducted a prospective study on the prognostic impact of depression, anxiety, and the comorbidity of the two among angina pectoris (AP) patients.

METHOD

In this prospective study, 443 patients with AP were included in the analysis. Follow-up assessments were performed 1 year, and 2 years after patient discharges. Clinical outcomes of interest included noncardiac readmission, major adverse cardiovascular events (MACEs), and composite events. Depression and anxiety symptom scores derived from the patient health questionnaire-9 (PHQ-9) and generalised anxiety disorder-7 (GAD-7) questionnaire were used to assess mood symptoms at baseline. Participants with symptom scores of ≥10 on both the depression and anxiety questionnaires formed the clinical comorbidity subgroup. We used multivariable Cox proportional hazards models to evaluate the impact of individual mood symptom and comorbidity on clinical outcomes.

RESULTS

Among all the AP patients, 172 (38. 9%) were determined to have depression symptoms, 127 (28.7%) patients had anxiety symptoms and 71 (16.0%) patients suffered from their comorbidity. After controlling covariates, we found that patients who endured clinical depression (hazard ratio [HR] = 2.38, 95% confidence interval [CI] 1.06-5.33, p = 0.035) and anxiety ([HR] 2.85, 95% [CI] 1.10-7.45, p = 0.032) had a high risk of noncardiac readmission. Compared to participants with no mood symptoms, those with clinical comorbidity of depression and anxiety presented a greater risk of noncardiac readmission ([HR] 2.91, 95% [CI] 1.03-8.18, p = 0.043) MACEs ([HR] 2.38, 95% [CI] 1.11-5.10, p = 0.025) and composite event ([HR] 2.52, 95% [CI] 1.35-4.69, p = 0.004).

CONCLUSION

Depression and anxiety were found to have predictive value for noncardiac readmission among patients with AP. Furthermore, prognoses were found to be worse for patients with comorbidity of depression and anxiety than those with single mood symptom. Additional attention needs to be focused on the initial identification and long-term monitoring of mood symptom comorbidity.

[Aspects of liaison psychiatry care of patients in a university pain clinic]

BACKGROUND

Owing to a rise of psychosomatic comorbidities, the treatment of psychological disorders, which may negatively impact prognosis and therapy, is increasingly becoming a focus of attention for pain outpatient clinics.

AIM

This study investigates and discusses the advantages of liaison psychiatric care in a university pain clinic.

METHODS

In this retrospective study, we investigated all patients who presented to an anaesthesiologically led pain clinic between January and June 2014. The psychiatric history was taken by the liaison psychiatrist of the pain clinic.

RESULTS

In the period investigated, 485 patients were treated as outpatients. A psychiatric diagnosis was present 351 patients (72.4%). The distribution of the diagnoses was comparable with that of a consultation service. Adaptation and affective disorders dominated. The patients were preferentially treated with new generation antidepressants.

CONCLUSION

The constant presence of a liaison psychiatrist allows for timely, specialised care of pain patients in terms of a multimodal therapeutic approach.
