| ObjectiveBased on the ecosystem theory and the life crisis and personal growth model,to investigate the current situation and influencing factors of family care,coronary self-blame attribution and post-traumatic growth in patients with acute myocardial infarction in tertiary hospitals,to analyse their interrelationships,and to explore the interaction mechanisms of family care,coronary self-blame attribution and post-traumatic growth in patients with acute myocardial infarction,so as to provide a basis for improving disease prognosis and quality of life for patients with acute myocardial infarction.Research reference.MethodBetween March and October 2022,we selected patients with acute myocardial infarction from two tertiary care hospitals in Inner Mongolia Autonomous Region and conducted questionnaires using the Basic Information Questionnaire,the Family Care Scale,the Coronary Heart Disease Self-Reference Attribution Scale and the Post-Traumatic Growth Scale.The raw data were entered via Excel spreadsheets and statistical analysis was carried out using SPSS 22.0 and AMOS 26.0 statistical analysis programs.A one-way ANOVA study was conducted using (?)±S descriptive statistics to investigate the effects of family care scores,coronary heart disease self-blame attribution scores and post-traumatic growth in patients with acute myocardial infarction,and multiple linear regression analysis to investigate the three The study was conducted using multiple linear regression analysis to investigate the association between these three factors in order to obtain more accurate results.Using the AMOS structural equation modelling study,we found that family care had an important mediating effect on self-blame attributions in patients with acute myocardial infarction,thereby facilitating their growth.Result1.The total score of family care for patients with acute myocardial infarction in the three hospitals was(4.72±2.53),with an overall mean score of(0.94±0.63),and the scores for each dimension were,from highest to lowest,cooperative(1.00±0.52),mature(0.95±0.72),intimate(0.94±0.73),cooperative(0.91±0.76)and emotional(0.91±0.70)score.The total attribution score for coronary heart disease in patients with acute myocardial infarction was(26.39±9.29),with a mean entry score of(2.39±0.84),and the highest to lowest scores for each dimension were behavioural self-blame(14.40±5.12)and personality self-blame(11.98±4.72).The total score for post-traumatic growth in patients with acute myocardial infarction was(56.87±17.35),the mean score of the entries was(2.84±0.86),and the scores for each dimension from highest to lowest were relationship with others(17.23±5.24),personal strength(11.36±3.96),life perception(10.96±3.73),new possibilities(8.70±(2.98)points,and self-transformation(8.60±2.90)points.2.ANOVA analysis showed statistically significant differences in family care scores for acute myocardial infarction patients on monthly income,primary caregiver,and mode of payment for medical care(P < 0.05),statistically significant differences in attributions of coronary heart disease self-blame for acute myocardial infarction patients on gender and presence of religion(P < 0.05),and statistically significant differences in post-traumatic growth for acute myocardial infarction patients on age,ethnicity,monthly income,There were statistically significant differences in age,ethnicity,monthly income,presence of religious beliefs,marital status,and education level(P < 0.05).3.Multiple linear regression analysis showed that monthly income,primary caregiver and mode of payment for medical care were influential factors for family care in patients with acute myocardial infarction(P < 0.01),gender and the presence of religious beliefs were influential factors for attribution of self-blame for coronary heart disease in patients with acute myocardial infarction(P < 0.01),and age,ethnicity,marital status and literacy were influential factors(P < 0.01).4.Pearson’s correlation analysis showed that the total family care score of patients with acute myocardial infarction was negatively correlated with their total coronary self-blame attribution score(r =-0.625,P < 0.01),the total family care score of patients with acute myocardial infarction was positively correlated with their total post-traumatic growth score(r= 0.640,P < 0.01),and the total coronary self-blame attribution score of patients with acute myocardial infarction was negatively correlated with their total post-traumatic growth score(r=-0.625,P < 0.01).There was a negative correlation(r =-0.668,P < 0.01).5.Structural equation modelling showed that family care for patients with acute myocardial infarction directly and positively predicted patients’ level of post-traumatic growth with an effect value of 8.002(95% CI: 2.703-11.336,p<0.01),family care for patients with acute myocardial infarction negatively predicted patients’ level of coronary heart disease self-blame attribution with an effect value of 6.339(95% CI: 3.503 to 13.927,P < 0.01),and the total effect of acute myocardial infarction patients on their level of post-traumatic growth was 14.341(95% CI: 10.492 to 20.386,P < 0.01),with the mediating effect accounting for44.20% of the total effect.Conclusions1.Family care for patients with acute myocardial infarction in tertiary care hospitals was at an intermediate level,with the highest scores for the cooperation dimension.Coronary heart disease self-blame attribution in patients with acute myocardial infarction in tertiary care hospitals was at an above-average level,with the lowest scoring dimension being the character self-blame dimension.Post-traumatic growth in patients with acute myocardial infarction in tertiary care hospitals was at an intermediate level,with the highest scoring dimension being the relationship with others dimension.2.Post-traumatic growth of acute myocardial infarction patients was positively correlated with their family care,negatively correlated with coronary self-blame attribution,and negatively correlated with family care and coronary self-blame attribution in acute myocardial infarction patients.The higher the degree of perceived family care and the lower the degree of coronary self-blame attribution in acute myocardial infarction patients,the higher their level of post-traumatic growth.3.Perceived family care and post-traumatic growth of acute myocardial infarction patients both negatively predicted the level of coronary self-blame attribution,and perceived family care of acute myocardial infarction patients directly positively predicted their level of post-traumatic growth,and also negatively predicted their level of post-traumatic growth through coronary self-blame attribution,which partially mediated the relationship between family care and post-traumatic growth of acute myocardial infarction patients.4.Patients with acute myocardial infarction perceive that high levels of family care and low levels of coronary self-blame attributions have a positive effect on improving post-traumatic growth,and healthcare professionals should increase the support of relatives around patients with acute myocardial infarction to reduce patients’ self-blame in the face of illness,thereby enhancing post-traumatic growth in patients with acute myocardial infarction,promoting patients’ self-adjustment to illness,and reducing patients’ adverse effects in the face of stressful events.This will enhance the level of post-traumatic growth of patients with acute myocardial infarction,promote disease self-adjustment and reduce the adverse effects of stressful events. |
