Methods are provided for estimating key reliably and accurately predicting cardiac output using a limited set of non-invasively monitored physiologic inputs, and a calibrated one-dimensional arterial tree model, a database of synthetic data generated from such a model, and an artificial intelligence module. Systems for estimating CO based on non-invasively measured physiologic inputs also are provided that may be implemented without the need for extensive real-time computing resources.

A computer-implemented method includes obtaining, via a processing system comprising one or more processors, a three-dimensional (3D) coronary tree segmented from computed tomography (CT) cardiac scan data of a subject, wherein the 3D coronary tree is labeled. The computer-implemented method also includes obtaining, via the processing system, a standardized two-dimensional (2D) coronary base schematic representation of a generic coronary tree. The computer-implemented method further includes modifying, via the processing system, the standardized 2D coronary base schematic representation of the generic coronary tree based on the 3D coronary tree to generate a standardized 2D coronary personalized schematic representation of a coronary tree of the subject.
