Objective To explore the effect of evidence-based nursing health education on the rehabilitation effect and quality of life in patients underwent cardiac valve replacement

so as to provide reference for clinical treatment. Methods Eighty patients who underwent heart valve replacement in the First Affiliated Hospital of Nanyang Medical College from April 2019 to May 2020 were selected as the study subjects. The patients were assigned to the control group and observation group by random number table

with 40 cases in each group. The patients in the control group received routine nursing intervention

and the patients in the observation group evidence-based nursing health education in addition to the nursing in the control group. Postoperative ICU stay（time from ICU admission to transfer to the general ward after surgery） and total length of hospital stay（time from admission to discharge） were compared between the two groups. The 36-Item Short Form Health Survey（SF-36） was used to assess the quality of life of patients in the 2 groups before and at 1 month of intervention. Results The postoperative ICU stay and total length of hospital stay in the observation group were significantly shorter than those in the control group（P<0.05）. Before the intervention

there was no significant difference in mental health

emotional function

social function

energy

physical pain

general health

role of physiology

and physical function scores in the SF-36 between the 2 groups（P >0.05）. After the intervention

the scores of mental health

emotional function

social function

energy

physical pain

general health

role of physiology and physical function in the SF-36 in the two groups were significantly higher than those before the intervention

with the observation group significantly higher than the control group（P<0.05）. Conclusion The use of evidence-based nursing health education in postoperative care for patients underwent heart valve replacement can promote the recovery of patients’ conditions

and improve their quality of life

with marked effects. These advantages justify a wider application of this nursing clinically.
