Objective To explore the effect of integrated nursing of of doctors and nurses in patients with coronary heart disease（CHD） after percutaneous coronary intervention（PCI）. Methods A total of 90 patients with CHD treated with PCI in a hospital in Liaoning Province from June 2018 to June 2019 were randomly divided into integrated groupand control group

with 45 cases in each group. The patients in the control group were given routine nursing after operation

and the patients in the integration group were treated with integrated nursing care after operation

and were followed up for 1 year. The self-management ability

blood pressure

blood glucose and blood lipid levels

quality of life

drug compliance rate 1 year after operation

stent stenosis and major adverse cardiac events were compared between the two groups before and after nursing intervention. Results After nursing intervention

the scores of all dimensions and total scores of coronary self-management scale（CSMS） in the integrated group were higher than those before nursing intervention and also higher than those in the control group

and the differences were statistically significant（P<0.05）. One year after operation

the drug compliance rate of hypoglycemic drugs in the integration group was significantly higher than that in the control group

and the differences were statistically significant（P <0.05）. After nursing intervention

the levels of systolic blood pressure

diastolic blood pressure and total cholesterol in the integration group were lower than those before intervention and also lower than those in the control group

and the differences were statistically significant（P<0.05）. After nursing intervention

the scores of physiological function

role physical

vitality

social function

emotional function

mental health and general health of Shot Form 36（SF-36） in the integrated group were significantly higher than those before nursing intervention and also higher than those in the control group

and the differences were statistically significant（P<0.05）. After nursing intervention

the score of body pain of SF-36 scale in the two groups was lower than that before nursing intervention

and that in the integration group was lower than that in the control group

and the difference was statistically significant（P<0.05）. One year after operation

the recurrence rate of angina pectoris in the control group was significantly higher than that in the integrated group（P<0.05）. Conclusion Integrated nursing care of doctors and nurses can effectively establish selfnursing awareness of patients with CHD after PCI

improve their disease self-management ability

and help to reduce the risk of postoperative adverse cardiovascular events.
