The invention relates to the field of medical diagnosis, in particular to a system for predicting the mortality risk after myocardial infarction. The system comprises an admission controller, a serumcreatinine detection component, a blood sugar detection component, a sample information receiving function module, an assignment module, a risk calculating module and a report system main interface, wherein the risk calculating module receives assigned values from the assignment module, and calculates according to a total score of the assigned values to obtain the mortality risk after the myocardial infarction. The system is easy to operate, and an assessment result is intuitively displayed; after adoption of the system provided by the invention, reasonable risk detection can be accurately andrapidly performed among a female cardiovascular disease population and individualized precise treatment strategies are guided, so that the system has an important clinical application value.
