Abstract: ObjectiveTo investigate the status of social support, level of hope, negative emotion and compliance behavior of patients with coronary heart disease(CHD) after percutaneous coronary intervention(PCI), and further explore the relationship between social support, and level of hope, negative emotion and compliance behavior.MethodsA total of 93 CHD patients treated with PCI were selected using simple random sampling method.The patients were investigated, which included the general information, social support rating scale(SSRs), Herth hope index(HHI), self-rating anxiety scale(SAS), self-rating depression scales(SDS) and compliance behavior.The correlation between social support, and level of hope, negative emotion and compliance behavior of CHD patients treated with PCI was analyzed.ResultsThe scores of social support scale, level of hope, anxiety, depression and compliance behavior in CHD patients treated with PCI were(41.15±6.48) points, (35.75±5.84) points, (45.25±5.64) points, (48.35±6.12) points and(4.38±0.87) points, respectively.The results of univariate analysis showed that the differences of the scores of social support rating scale among different levels of family monthly income CHD patients treated with PCI were statistically significant(P < 0.05).The results of Pearson correlation analysis showed that the social support rating score and each dimension score were negatively correlated with the scores of anxiety and depression(P < 0.01), and positively correlated with the scores of level of hope and each dimension and compliance behavior score(P < 0.05 to P < 0.01).The results of multiple linear regression analysis indicated that the level of hope, anxiety, depression and compliance behavior could affect the social support of CHD patients treated with PCI(P < 0.05 to P < 0.01).ConclusionsThe social support, level of hope and compliance behavior of CHD patients treated with PCI are at a moderate level.The anxiety and depression in part of patients also occur, and the level of hope, anxiety, depression and compliance behaviors are associated with social support.
