The invention provides a myocardial infarction early warning method, device and equipment and a storage medium. The myocardial infarction early warning equipment comprises a processor and a memory connected with the processor; the processor is used for obtaining real-time data, related to heart health, of a target object collected by a wearable device; the memory is used for storing historical diagnosis and treatment data of the target object and a pre-trained first prediction model; the processor is further used for inputting the historical diagnosis and treatment data and the real-time datainto the pre-trained first prediction model to obtain a first score of the myocardial infarction risk of the target object; and performing myocardial infarction early warning according to the first score of the myocardial infarction risk. The myocardial infarction early warning equipment is high in practicability and early warning accuracy.
