Abstract: A method for determining an index for assessing a cardiac function of a subject, includes performing, by elastography, first and second liver stiffness measurements to obtain first and second values of a liver stiffness parameter of the subject, the first and second values being associated with first and second times; determining, by a processing circuit, the index of the cardiac function based on the first and second values, and outputting, via a graphical user interface of a device, the determined index of the cardiac function of the subject. The first value corresponds to a value of the liver stiffness parameter before or immediately after performing a predetermined cardiac stimulation that modifies a cardiovascular system of the subject and the second value corresponds to a value of the liver stiffness parameter obtained after performing the first liver stiffness measurement.
