Cardiovascular disease is the leading cause of death in China and the world. Emergency coronary
intervention can save the life of patients with myocardial infarction, and rehabilitation after intervention is a
complicated and long-term process. The rehabilitation effect of acute myocardial infarction has been verified by
many research institutes. At present, the domestic cardiac rehabilitation is mainly in-hospital rehabilitation and
family community rehabilitation. Cumbersome procedures, fixed rehabilitation time and often conflict with
working hours, lack of family support, inconvenient transportation, high costs and other reasons lead to low
rehabilitation participation rate and unsatisfactory compliance. Most patients with myocardial infarction only
receive simple rehabilitation instructions before discharge, such as gradually increasing the amount of activity,
changing bad eating habits, quitting smoking and drinking, etc. The content is not specific. Sports training in
lifestyle interventions is considered to be an effective method for preventing and treating cardiovascular diseases.
Based on the above background, the research content of this article is animal experiments to analyze the cardiac
movement rehabilitation of athletes with acute myocardial infarction. This article proposes the hypothesis that
pre-infarction exercise combined with post-infarction exercise may improve rat left ventricular remodeling and
prognosis. In order to verify this hypothesis, experimental simulations were carried out in this paper, and the
results showed that compared with the rats in the Sed-MI group, the left ventricular weight and the right
ventricular weight of the MIE-Sh group increased slightly (P> 0.05), but the heart weight. The weight ratio
increased significantly (P <0.05). However, rats in the HIE-MI group significantly increased left ventricular
weight, right ventricular weight, and heart-weight-to-weight ratio. It is confirmed that the combination of
pre-myocardial infarction and post-infarction exercise is better than pre-infarction exercise or post-infarction
exercise in improving left ventricular remodeling and prognosis.
