Objective To investigate the effects of acceptance and commitment therapy (ACT) intervention on the incidence of cardiovascular adverse events and psychological state in patients after percutaneous coronary intervention (PCI).

Methods A total of 80 patients after PCI were selected and randomly divided into control group and intervention group using a random number table method, with 40 cases in each group. The control group received routine nursing measures, while the intervention group received an ACT intervention program in addition to routine nursing. The incidence of cardiovascular adverse events after intervention was statistically analyzed in both groups. The scores of the coronary heart disease Self-efficacy Scale (CSES), Self-rating Anxiety Scale (SAS), Self-rating Depression Scale (SDS), and Acceptance and Action Questionnaire-Ⅱ (AAQ-Ⅱ) were compared between the two groups.

Results After intervention, the incidence of adverse cardiovascular events in the intervention group (5.00%) was significantly lower than that in the control group (12.50%). The CSES score in the intervention group was significantly higher than that in the control group (45.53±3.81) versus (39.23±3.62), the SAS score was lower than that in the control group (46.09±3.62) versus (54.63±2.45), the SDS score was lower than that in the control group (49.53±2.87) versus (52.24±2.45), and the AAQ-Ⅱ score was lower than that in the control group (21.43±1.96) versus (31.45±4.25) (P < 0.05).

Conclusion ACT intervention can effectively improve the self-efficacy and psychological flexibility of patients after PCI, alleviate anxiety and depression, and significantly reduce the incidence of cardiovascular adverse events.
