Method and system for determining strain relaxation of left ventricular diastolic function

A device, comprising:

• one or more memories;
• and
• one or more processors, communicatively coupled to the one or more memories, configured to:
• obtain, from an imaging modality, a plurality of cardiac images of a subject;
• determine, from the plurality of cardiac images of the subject, a first time associated with a systolic strain peak, a second time associated a post-systolic strain peak, and an early diastolic strain peak;
• compute a strain rate index (SRI) value using the first time associated with the systolic strain peak, the second time associated with the post-systolic strain peak, and the early diastolic strain peak,
• the SRI being computed based upon a difference between the first time associated with the systolic strain peak and the second time associated with the post-systolic strain peak divided by the early diastolic strain peak;
• determine a level of risk of cardiac failure using the SRI value;
• determine a treatment plan for the subject based on the level of risk of cardiac failure;
• and
• provide information associated with the level of risk of cardiac failure and the treatment plan for review by a medical professional.

A non-transitory computer readable medium storing instructions comprising:

• one or more instructions that, when executed by one or more processors, cause the one or more processors to be configured to:
• obtain, from an imaging modality, a plurality of cardiac images of a subject;
• determine, from the plurality of cardiac images of the subject, a first time associated with a systolic strain peak, a second time associated with a post-systolic strain peak, and an early diastolic strain peak;
• compute a strain rate index (SRI) value using information associated with the first time associated with the systolic strain peak, second time associated with the post-systolic strain peak, and the early diastolic strain peak,
• the SRI being computed based upon a difference between the first time associated with the systolic strain peak and the second time associated with the post-systolic strain peak divided by the early diastolic strain peak;
• determine a level of risk of cardiac failure using the SRI value;
• determine a treatment plan for the subject based on the level of risk of cardiac failure;
• and
• provide information associated with the level of risk of cardiac failure and the treatment plan for review by a medical professional.
