Abstract

Background: Evidence suggests that coronary heart disease (CHD) is associated with increased anxiety and a high incidence of comorbid anxiety and depression. However, the association between percutaneous coronary intervention (PCI) and comorbid anxiety and depression has not been previously investigated. This study aims to determine the relationship between PCI and anxiety and depression symptoms in CHD patients in terms of the occurrence, prone factors, and long-term outcomes of CHD.

Methods: One hundred seventy CHD patients who underwent PCI treatment between September 2013 and February 2014 at the Second Hospital of Hebei Medical University were randomly selected. All patients independently completed the Hospital Anxiety and Depression Scale (HADS) and a preoperative questionnaire; they also provided details regarding their PCI-related concerns one day before PCI, as well as one day and one, three, six, and 12 months after PCI.

Results: PCI treatment was significantly associated with the symptoms of anxiety, depression, affective disorders, and comorbid anxiety and depression (χ(2) = 90.18, 54.45, 101.59, 64.83; p < 0.01) at each follow-up time point. Moreover, PCI treatment was linearly correlated with each of these psychological issues (p < 0.01).

Conclusion: The prevalence of anxiety, depression, and comorbid anxiety and depression symptoms significantly increases one day before and after PCI treatment; however, the incidence of these psychological issues significantly decreases with time following PCI. A low level of education, apprehension with regard to nursing quality, potential cardiac dysfunction, surgery sequelae, and surgery failure are also associated with a high prevalence of anxiety and depression symptoms.

Keywords: Anxiety and depression symptoms; Coronary artery disease; Percutaneous coronary intervention.
