Abstract: In order to explore the effect of continuous nursing in interventional therapy (PCI) for patients with coronary heart disease (CHD),80 CHD patients who underwent PCI between January 2024 and April 2024 were selected as the study subjects.Patients were randomly divided into observation group (conventional nursing combined with continuous nursing mode) and control group (conventional nursing mode) with 40 cases in each group.The quality of life score,negative emotion score and complication rate of patients before and after nursing were compared.The results showed that the quality of life score after nursing in the observation group was significantly higher than that in the control group,and the difference between groups was statistically significant (P<0.05).The negative emotion score of the observation group after nursing was significantly lower than that of the control group,and the difference between groups was statistically significant (P<0.05).The incidence of adverse reactions after nursing in the observation group was significantly lower than that in the control group,and the difference between groups was statistically significant (P<0.05).For CHD patients undergoing PCI,continuous nursing has shown positive effects on improving quality of life,alleviating negative emotions,and reducing the incidence of complications.
