Abstract：Objective To investigate the application effect of evidence-based nursing in patients with dilated cardiomyopathy.Methods A total of 76 patients with dilated cardiomyopathy who were admitted to the hospital from June 2017 to June 2019 were selected as the research subjects,and they were divided into control group (38 cases) and observation group (38 cases) according to random number table.The control group received routine nursing,and the observation group took evidence-based nursing.The cardiac function,mastery degree of disease and quality of life were compared between the two groups.Results After intervention,the left ventricular ejection fraction (LVEF) and 6-minute walking test in two groups were higher than those before intervention,and the above indexes in observation group were higher than those in control group,the differences were statistically significant (P<0.05);after intervention,the score of each dimension of mastery degree of disease knowledge questionnaire in observation group was higher than that in control group,and the differences were statistically significant (P<0.05);after intervention,the physical,psychological,independence,social relationship,environment,spiritual/faith scores in the two groups were higher than those before intervention,and the above scores in observation group were higher than those in control group,the differences were statistically significant (P<0.05).Conclusion Evidence-based nursing for patients with dilated cardiomyopathy can increase LVEF and walking distance,thus improving the cardiac function;and it can increase the mastery degree of disease knowledge and the level of quality of life,which has better clinical intervention effects.
