Abstract: Objective: To explore the correlation between post-traumatic growth and psychological resilience and rumination in patients with coronary heart disease undergoing percutaneous coronary intervention (PCI). Methods: A total of 205 patients with coronary heart disease treated by PCI were selected as the study subject.The self-made general information questionnaire was used to collect their general information,and the scores of PTGI,CD-RISC and C-ERRI were collected.Pearson correlation analysis was used to analyze the correlation between general information,CD-RISC score,C-ERRI score and PTGI score of patients with coronary heart disease treated by PCI. Results: There was a positive correlation between educational level and psychological resilience (P<0.01).Marital status was negatively correlated with growth trauma (P<0.01).Residence was positively correlated with psychological resilience (P<0.01).There was a positive correlation between family monthly per capita economic income and psychological resilience (P<0.05).Growth trauma was positively correlated with psychological resilience and ruminative contemplation (P<0.01).There was a positive correlation between resilience and ruminant contemplation (P<0.01).When PTG and psychological resilience had an impact on ruminant meditation,the SPC was 0.182 and 0.187,respectively,both of which were >0,and the path showed significance at the level of 0.05 (Z=2.283,2.340,P<0.05).It showed that PTG and psychological resilience had a positive effect on rumination. Conclusions: The post-traumatic growth of patients with coronary heart disease treated by PCI is positively correlated with psychological resilience and ruminant contemplation.At the same time,the education level,marital status,residence,and monthly per capita economic income of the family will all have an impact on the post-traumatic growth,psychological resilience and ruminant contemplation of patients.
