1. A computer-implemented method for monitoring hemodynamic risk of a patient, the method comprising:
acquiring a patient-specific model of blood flow through at least a portion of a patient's vasculature;
obtaining a current patient-specific parameter of the patient;
determining a current hemodynamic characteristic of the patient based on the patient-specific model and the current patient-specific parameter of the patient;
obtaining a maximum allowable hemodynamic characteristic of the patient;
comparing the current hemodynamic characteristic with the maximum allowable hemodynamic characteristic;
determining, based on the comparing, whether the current hemodynamic characteristic includes an abnormal value; and
in response to determining that the current hemodynamic characteristic includes an abnormal value, producing a warning indicative of the abnormal value.
