An interventional study on the application of heart-collateral-based enlightenment words intervention in anxiety and depression of patients after percutaneous coronary intervention

Objective: To study the effect of heart-collateral-based enlightenment words intervention on anxiety and depression in patients following percutaneous coronary intervention (PCI).

Methods: In this class experimental study, one hundred patients who were hospitalized after PCI from May 2020 to October 2021, were included in this interventional study. They were divided into the test group (n = 50) and the control group (n = 50) based on the random number table. The heart-collateral-based enlightenment words intervention was used in the test group versus routine nursing in the control group. Data was collected using a self-rating anxiety scale (SAS), self-rating depression scale (SDS), and an independently developed satisfaction questionnaire. Psychological indicators and satisfaction were compared between the two groups before and after the intervention.

Results: After 3 months of intervention, the test group scored significantly lower in SDS and SAS than the control group (SDS score: [55.06 ± 8.63] vs. [62.90 ± 9.52]; SAS score: [46.83 ± 10.24] vs. [56.02 ± 8.92]) (P < 0.05 for both SDS and SAS difference). The satisfaction rate of the test group vs. control group was 96% vs. 82% after the intervention, with a statistically significant difference (P < 0.05).

Conclusion: Heart-collateral-based enlightenment words intervention can effectively alleviate anxiety and depression in patients after PCI and increase their satisfaction with nursing services. To develop the theory and guide clinical practice, future research in different treatment area with larger sample size should be conducted.
