ObjectiveTo explore the effect of interactive virtual scenario training in patients with heart failure after myocardial infarction. MethodsEighty patients with heart failure after myocardial infarction were selected as research subjects and randomly divided into a control group or an observation group, with 40 cases in each group. The control group underwent regular aerobic exercise, based on which the observation group underwent interactive virtual scenario training, and both groups were intervened for 8 weeks. The two groups were compared in the cardiac function, 6 minutes walking test (6MWT) distance, self-care ability, and sleep quality before and after the intervention. ResultsAfter 8 weeks of intervention, the left ventricular ejection fraction, left ventricular end-diastolic volume, left atrial diameter, 6MWT distance, and Barthel index in the observation group were higher/longer than those in the control group, and the ratio of the peak mitral blood flow velocity in the early diastole to peak mitral blood flow velocity in the late diastole and Pittsburgh sleep quality index in the observation group were lower than those in the control group (all P＜0.05). ConclusionInteractive virtual scenario training can improve cardiac function, walking ability, self-care ability, and sleep quality in patients with heart failure after myocardial infarction, which is worthy of clinical promotion and application.
