Objective  To analyze value of health education under the guidance of multidisciplinary team for patients with type 2 diabetes mellitus (T2DM) complicated with coronary artery disease after percutaneous coronary intervention (PCI).

  Methods  A total of 82 patients with T2DM and coronary heart disease who underwent PCI were divided into control group and observation group according to the random number table method, with 41 cases in each group, given routine health education or health education under the guidance of multidisciplinary team, respectively. The compliance behaviors, self-efficacy, disease cognition degree and blood glucose control were compared between the two groups after intervention.

  Results  Before intervention, there were no significant differences between the two groups in terms of dimension scores of compliance behaviors, self-efficacy scale and dimension scores of disease cognition (P>0.05), and the scores of above in the two groups were increased after 6 months of intervention (P < 0.05), and the observation group was higher than the control group (P < 0.05). Before intervention, there was no significant difference in blood glucose level between the two groups (P>0.05). After 6 months of intervention, the overall blood glucose levels in the two groups were decreased (P < 0.05), and the observation group was higher than the control group (P < 0.05).

  Conclusion  Health education under the guidance of multidisciplinary team for T2DM patients with coronary heart disease after PCI can improve the compliance degree, strengthen self-efficacy and promote the disease cognition, thus optimizing blood glucose control.
