Virtual Stress Test Based on Electronic Patient Data

A computer-implemented method of performing a virtual stress test for a patient, the method comprising:

• obtaining a geometric representation of an arterial segment of the patient, the arterial segment comprising an inflow boundary and two or more outflow boundaries;
• receiving metabolic requirement information of the patient;
• determining a threshold according to the metabolic requirement information;
• obtaining a first inflow rate respective of the inflow boundary;
• calculating first outflow rates at the two or more outflow boundaries according to the first inflow rate;
• calculating a first flow field in the arterial segment according to the geometric representation, the first inflow rate, and the first outflow rates;
• determining a first pressure drop in the arterial segment based on the first flow field;
• obtaining a second inflow rate respective of the inflow boundary, the second inflow rate different from the first inflow rate;
• calculating second outflow rates at the two or more outflow boundaries according to the second inflow rate;
• calculating a second flow field in the arterial segment according to the geometric representation, the second inflow rate, and the second outflow rates;
• determining a second pressure drop in the arterial segment based on the second flow field;
• calculating, based on the first pressure drop and the second pressure drop, a range of pressure drops for a range of inflow rates;
• comparing the range of pressure drops to the threshold;
• and
• displaying a result of the comparison.
