Claim 15:
16. A system configured to evaluate a patient for potential interventional cardiac therapy, comprising:
an MRI workstation in communication with an MRI scanner, wherein the MRI workstation and/or a remote module in communication with the MRI workstation is configured with at least one processor and/or server configured to:
direct the MRI scanner to transmit strain encoded pulse sequences of long and short axis planes of a heart of a human patient;
obtain MRI images of the heart of the human patient;
electronically contour tissue in the obtained MRI images to delineate circumferential and longitudinal segments of the heart;

determine a plurality of strain measurements from the obtained MRI images, the plurality of strain measurements comprising respective strain measurements for a first number of defined circumferential segments and respective strain measurements for a second number of defined longitudinal segments, wherein the first number and the second number are summed to provide an overall number of segments; and
calculate a risk score based on how many of the defined longitudinal and circumferential segments have a respective strain measurement that is equal to or less than −17% associated with healthy/normal contractility at peak contraction, divided by the overall number of segments, wherein the −17% defined threshold strain measurement is a universal norm for both genders and all ages, and wherein the risk score is provided in a numerical range with a first end of the numerical range associated with a healthy (normal) heart and a second end of the numerical range corresponding to heart failure thereby providing a measure of current status of cardiac health.
