[Involvement characteristics and influencing factors of anxiety and depression in patients after percutaneous coronary intervention].

OBJECTIVE

To explore the involvement characteristics and influencing factors of anxiety and depression in patients after percutaneous coronary intervention (PCI).

METHODS

A total of 396 patients undergoing PCI were investigated between January 2009 and December 2010. All of them completed the Hospital Anxiety and Depression Scale (HADS) before discharge and at 12 months post-PCI. We evaluated the involvement characteristics and used Logistic regression to analyze the influencing factors of mood changes.

RESULTS

The relevant factors of post-PCI anxiety were gender (P = 0.003), age (P = 0.004) and acute myocardial infarction (P = 0.009) while depression was associated with acute myocardial infarction (P < 0.001). A 12-month follow-up study showed that anxiety remained stable in 76.3% of patients while depression in 79.5%. Multi-factor analysis showed that factors of presence of adverse cardiovascular events (OR: 1.323, 95%CI: 1.026 - 1.705, P = 0.031), Seattle angina score (OR: 0.870, 95%CI: 0.772 - 0.981, P = 0.023) and anxiety scores at pre-discharge (OR: 1.228, 95%CI: 1.053 - 1.432, P = 0.009) were correlated with the deterioration degree of depression. And the factor associated with the deterioration of depression was the scores before discharge (OR: 1.287, 95%CI: 1.072 ∼ 1.545, P = 0.007).

CONCLUSION

The levels of anxiety and depression remain stable in the majority of PCI patients at Month 12 post-PCI. Perioperative communication and effective control of postoperative cardiovascular events may ease a patient's negative emotions and improve their living quality.
