ObjectiveTo understand the current status of medication compliance in patients with coronary heart disease after percutaneous coronary intervention(PCI), and to analyze the mediating effect of mindfulness psychological trait on health literacy and medication compliance.

MethodsThe convenience sampling method was used to select 212 patients with coronary heart disease after PCI as the research objects.The general situation questionnaire, five-factor mindfulness scale, health literacy of patients with chronic diseases and Morisky medication compliance scale were used to conduct questionnaire survey.Pearson analysis was used to analyze the correlation between mindfulness psychological trait, health literacy and medication compliance, and a structural equation model was established to test the mediating effect.

ResultsThe total score of mindfulness psychological trait of patients with coronary heart disease after PCI was (96.76±10.64) points, the total score of health literacy was (87.55±9.47) points, and the total score of medication compliance was (6.24±0.72) points.Pearson analysis results showed that the total scores of mindfulness psychological trait and 4 dimensions were positively correlated with the total scores of health literacy and 3 dimensions (P < 0.05 to P < 0.01);the total scores of mindfulness psychological trait and the 4 dimensions were positively correlated with the total scores of medication compliance (P < 0.01);the total score of health literacy and the 4 dimensions were positively correlated with the total score of medication compliance (P < 0.01).The results of the structural equation model showed that the mindfulness psychological trait had a partial mediating effect between health literacy and medication compliance, and the mediating effect accounted for 35.38% of the total effect.

ConclusionsThe scores of mindfulness psychological trait, health literacy, and medication compliance in patients with coronary heart disease after PCI are all at a moderate level.There is a close positive correlation between medication compliance and health literacy and mindfulness psychological trait in patients.Mindfulness psycholegical trait has 35.38% mediating effect between health literacy and medication compliance.
