Abstract: Objective To investigate the correlation between health promotion behavior and health belief of patients with coronary heart disease （CHD） after percutaneous coronary intervention （PCI）. Methods All patients who underwent PCI in Hainan Provincial Hospital of Traditional Chinese Medicine from June 2015 to June 2016 were enrolled. The health promotion behavior and health beliefs of patients after PCI were investigated by general situation questionnaire,the improved health promoting lifestyle scale Ⅱ （HPLP Ⅱ） and health belief scale. Factors influencing health promotion behavior and health beliefs and their correlation were analyzed. Results A total of 104 patients who underwent PCI were investigated, including 70 males and 34 females, with an average age of （55.72 ± 13.69） years. The average duration of disease was （78.64 ± 31.57） months and average body mass index （BMI）was（27.67 ± 3.46）. The multiple stepwise regression model showed that gender and education level were main factors influencing the health beliefs of patients after PCI （β=7.165, 4.856,P<0.05 or P<0.01）; the education level, per capita monthly income of families, and BMI were main factors influencing the health-promoting behaviors of patients after PCI （β=5.114, 3.625, 8.160; P<0.05 for all）. The health promotion behavior was positively correlated with health beliefs in patients with CHD after PCI （r=0.216）; perceived severity score was negatively correlated with self-actualization and physical exercise scores （r =-0.213, -0.236）; perceived health benefit score was positively correlated with the overall scores of health promotion behavior and self-actualization, nutrition and stress management （r=0.238, 0.246, 0.279）; the healthy motivation was positively correlated with total score of health promotion behavior and the score of each dimension （r=0.358, 0.374, 0.326, 0.204, 0.304, 0.318, 0.301）. Conclusion Health beliefs was correlated with health promotion behaviors of patients with CHD after PCI; the greater the perceived benefit of health behavior and the stronger the motivation to maintain the health, the higher the level of health promotion behavior.
