Influence On Coronary Risk Factor By A Comprehensive Health Education Intervention Programme In Patients After Percutaneous Coronary Intervention

Objective: The objective of the present study was to determine whether a long-term comprehensive health intervention programme with a dedicated medical director, along with an interdisciplinary team approach, including hospital and community could favourably influence coronary risk factors(CRF) in patients after percutaneous coronary intervention and improvement Secondary prevention interventions for patients after PCI.Methods: Concurrent randomized control trials were conducted in this study. A consecutive series of eligible patients was recruited from three hospitals in Tai yuan city, shan xi province, China after their first percutaneous coronary intervention between November 1 and November 30, 2006. After obtaining informed consent, a total of 127 patients after PCI were included and randomised to a comprehensive intervention programme(IP) or to usual care(UC). Both groups were given the same comprehensive medication. At baseline all participants were asked to offer their demographic, medication status and underwent risk factor assessment (physical and laboratory examination). After a period of 6 months and 12 months of intervention, all participants were invited to undertaken the same factor assessment as baseline successively. 2007 AHA/ACC PCI Secondary Prevention Guidelines and relative recommendations of WHO were selected as the criterion of evaluation. Independent sample t-tests, wilcoxon rank sum test, Chi-square test were used to evaluate differences in basic demographic, medical characteristics and coronary risk factors between the two study groups. univariate analyses, The [chi]2 statistic and Mantel-Haenszel were used to identify intervention, medical characteristics associated with effectiveness rates of CRF controlled of 6 months later and 12months later. Logistic regression was computed to evaluated the effectiveness of intervention in coronary risk reduction. Level of significance for all tests is P=0.05 (two-tailed).Results: There were no differences between the two groups in baseline sociodemographic, medical characteristics or risk factors, suggesting that there was no systematic bias attributable to differences in the intervals to the follow-up interviews. In the univariate analyses, IP and medication after 6 months were associated with effectiveness rates of controlling LDL-C, BMI, WC, physical activity. When all the relative variables were entered into a logistic regression analysis, IP emerged as significant in increasing the likelihood of managing LDL-C, BMI, WC, physical activity. IP after 12 months was associated with effectiveness rates of controlling all seven CRFs. When all the relative variables were entered into a logistic regression analysis, IP emerged as significant in increasing the likelihood of standard managing all seven CRFs except FB.Conclusion: compared with usual care, comprehensive health intervention seems a more effective way to improved CRFs modification after PCI. This programme provide a method of prevention to decrease the rate of restenosis and further cardiovascular events.
