The invention provides a construction method of a coronary heart disease screening model, which comprises the following steps: performing myocardial acting analysis on cardiac ultrasonic section images of a group of objects to obtain myocardial acting parameters; taking the basic examination information of the group of objects and the myocardial acting parameters as input of a neural network model to obtain a coronary heart disease screening model; and correcting the coronary heart disease screening model by taking the diagnosis result of the group of objects as a standard. According to the method, myocardial acting analysis with the accuracy superior to that of spot tracking is adopted, obtained myocardial acting parameters are fused with basic examination information, an intelligent coronary heart disease screening model is constructed through a neural network, and correction is further carried out according to a diagnosis result of coronary artery angiography. The constructed coronary heart disease screeni
