Claim 0:
1. A method of monitoring and/or assessing cardiac health, comprising:
directing an MRI scanner to transmit a plurality of strain encoded pulse sequences for different long and short axis views of a heart of a human patient;
obtaining MRI images of the heart of the human patient;
electronically calculating a plurality of strain measurements from the obtained MRI images, the plurality of strain measurements comprising a first number of defined longitudinal left ventricular segments comprising basal, mid and apical sets of strain measurements, and a second number of defined circumferential left ventricular segments comprising two-chamber, three-chamber and four-chamber long axis sets of strain measurements, wherein the first number of defined longitudinal left ventricular segments and the second number of defined circumferential left ventricular segments are added together to provide an overall number of defined left ventricular segments; and
programmatically calculating a risk score, wherein the risk score is calculated based on a number of the first number of defined longitudinal left ventricular segments summed with a number of the second number of defined circumferential left ventricular segments that have a respective strain measurement value equal to or below −17% associated with peak strain of normal muscle contractibility across both genders and across different ages, divided by the overall number of the defined left ventricular segments, and wherein the risk score is provided to a patient report 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.
