The invention provides a carotid artery calcification index evaluation method, and relates to the technical field of medical treatment. According to the carotid artery calcification index evaluation method, a medical service platform, a patient terminal, an expert terminal and a medical institution system are included, and the patient terminal, the expert terminal and the medical institution system all establish data communication with the medical service platform; the medical service platform collects symptom features related to carotid artery calcification from the expert terminal and the medical institution system which establish communication, classifies the symptom features according to the types of the symptom features, and corresponds to the numerical value of the frequency after symptom classification according to the occurrence frequency of the symptom. By constructing a framework of a medical service platform, a patient terminal, an expert terminal and a medical institution system, convenience is provided for daily examination of people, people can judge the current state of the body carotid artery according to the finally obtained carotid artery calcification index by depending on the method, the operation process is very simple, special examination is not needed, and the efficiency is high. And the safety of the carotid artery can be ensured.
