The invention discloses a blood vessel quantization parameter prediction method and device, electronic equipment and a storage medium. Comprising the steps of obtaining medical image data, extracting a blood vessel center line based on the medical image data, and determining a to-be-predicted node based on the blood vessel center line; determining initialization data corresponding to different types of to-be-predicted nodes, wherein the initialization data comprises boundary condition data at a plurality of to-be-predicted moments, initial parameter data and one or more items of attribute information of the to-be-predicted nodes; inputting the initialization data of the to-be-predicted nodes into a pre-trained graph neural network prediction model to obtain a parameter prediction result of each to-be-predicted node at at least one to-be-predicted moment within a preset prediction time period; and determining the fractional flow reserve of the to-be-predicted node at the to-be-predicted moment based on the par
