Correlation Analysis Of Factors Affecting Self-management Ability Of Coronary Heart Disease Patients After PCI

Objective:To study the status quo of self-management ability of coronary heart disease patients after PCI in changchun and further analyze the related factors affecting the self-management ability of coronary heart disease patients after PCI.Methods:From November 2018 to November 2019,a total of 319 patients with coronary heart disease diagnosed by coronary angiography and undergoing PCI were included in the study.Data were collected by questionnaire,including:general information questionnaire,coronary heart disease self-management behavior scale,social support rating scale(SSRS),coronary heart disease self-efficacy scale(CSES)and post-traumatic growth scale(PTGI).SPSS 23.0software package,macro program and Systat 13.0 were used to process the data.Descriptive statistics,double-tail t test,chi-square test,analysis of variance,Pearson correlation analysis,multiple regression analysis and ridge regression analysis were used to analyze the data,and P<0.05 was considered as a significant difference.Ridge Regression macro program in SPSS23.0 was used for Ridge trace drawing,and Systat 13.0 was used for Ridge Regressionparameter analysis and mapping.Results:In this study,the score of self-management ability of patients after PCI was(69.35±6.32),and the score index was 66.1%,which was at a low level.The social support score was(43.62±6.24),lower than the domestic norm.The score of self-efficacy was(35.52±9.36),and the score index was 53.8%,which was a low level.The post-traumatic growth score was(59.26±6.27),and the total score?57 was the positive standard for post-traumatic growth.In this study,188 patients had a total score?57,and the positive detection rate was 58.9%,indicating that nearly half of the patients in this study had poor positive psychologicaltransformation.The results of single factor analysis show that:(1)Social support:there was a significant difference in monthly income among the totalgroup of self-management behaviors of coronary heart disease patients after PCI.In addition,monthly income,educational level,residential type,history of involvement and whether or not the first episode had an impact on different dimensions(P<0.05).(2)Self-efficacy:monthly income,history of intervention and first-episode status couldaffect the total score of self-efficacy of patients(P<0.05).The degree of education can affect the maintenance dimension of symptoms(P<0.05).The score of functional maintenancedimension was affected by the history of intervention and whether it was the first disease(P<0.05).(3)Post traumatic growth:monthly income,history of intervention,and whether or not a starter had an impact on the total score of post traumatic growth(P<0.05).There was a significant difference in the scores of mental change dimension between different genders(P<0.05).There were significant differences in the appreciation of life among patients withdifferent economic incomes(P<0.05).For the post-traumatic growth of patients,the history of intervention and whether they were the first episode all affected the new dimension ofpossibility and the dimension of appreciation of life(P<0.05).(4)Self-management ability:monthly income,history of intervention,first episode,socialsupport,self-efficacy score and post-traumatic growth score of coronary heart disease patients after PCI showed statistically significant differences(P<0.05).In addition,gender,age,education level,monthly income,first episode status,history of intervention,social support status,self-efficacy score and post-traumatic growth score all had influences on different dimensions of self-management behavior(P<0.05).The results of multi-factor analysis show that:The self-management ability of coronary heart disease patients after PCI was positively correlated with social support,self-efficacy and post-traumatic growth.Among them,symptom management dimension is negatively correlated with self-management ability.The results of ridge regression analysis show that,among the above 6 variables,only the level of social support and self-efficacy are the significant influencing factors of self-management ability.The ridge regression model was well fitted,and the fitting model R~2=0.92.Theequation of ridge regression model is y=0.46*X2+0.52*X3+28.85.Conclusion:(1)The self-management ability of patients after PCI in this region is at a low level,social support is lower than the domestic norm,and self-efficacy is at a low level.Nearly half of the patients have the phenomenon of adverse positive psychological transformation.(2)Social support and self-efficacy are the main influencing factors of patients'self-management ability after PCI.
