Objective To explore the application effect of blood pressure management based on the health belief model in patients with moyamoya disease after cerebral vascular reconstruction surgery.

Methods From February to July 2024, 210 patients with moyamoya disease who underwent cerebral vascular reconstruction surgery in our hospital were selected as study subjects. They were randomly divided into control group and intervention group, with 105 cases in each group. The control group received routine nursing care, while the intervention group applied blood pressure management based on the health belief model on the basis of routine nursing care. The postoperative cerebral hyperperfusion syndrome and blood pressure control status of the two groups were compared, and the Health Belief Scale and the Mishel Uncertainty in Illness Scale were used to evaluate the effects before and after intervention.

Results A total of 203 patients completed the study, including 100 cases in the control group and 103 cases in the intervention group. There were statistically significant differences in the incidence of cerebral hyperperfusion syndrome and the proportion of patients with blood pressure higher than baseline data between the two groups (P < 0.05). After the intervention, there were statistically significant differences in the postoperative cerebral hyperperfusion syndrome status and blood pressure control status between the two groups (P < 0.05). After intervention, there were statistically significant differences in the scores of susceptibility and health motivation dimensions as well as the total score in the Health Belief Scale between the intervention group and the control group (P < 0.05). After the intervention, there were statistically significant differences in the scores of ambiguity and unpredictability dimensions as well as the total score in the Mishel Uncertainty in Illness Scale between the intervention group and the control group (P < 0.05).

Conclusion Blood pressure management based on the health belief model can effectively control blood pressure, reduce the incidence of cerebral hyperperfusion, improve health beliefs, and reduce the sense of uncertainty about the disease.
