Hemodynamic parameter determination method and device, electronic equipment and storage medium

The invention provides a haemodynamic parameter determination method and device, electronic equipment and a storage medium, and the method comprises the steps: growing a blood vessel model of a myocardial blood vessel three-dimensional model in combination with a myocardial model in the myocardial blood vessel three-dimensional model to obtain a blood vessel tree model; limiting the blood vessel inlet flow of each blood vessel section in the blood vessel tree model through a flow control equation, and determining the blood vessel resting flow of each first tail end blood vessel section in the blood vessel tree model; cutting redundant blood vessel segments in the blood vessel tree model to obtain a cut blood vessel tree model; based on the blood vessel resting flow of each first tail end blood vessel section, determining the blood vessel inlet flow of the cut blood vessel tree model and the blood vessel outlet parameter of each second tail end blood vessel section; and determining hemodynamic parameters of th
