Global Ventricular Cardiac Diastolic Function Evaluation System and Associated Methods

A method for evaluating cardiac diastolic function, the method comprising:

• determining a first volume change rate during an initial diastolic flow period of a volumetric flow in a cardiac function;
• determining a second volume change rate during an intermediate diastolic flow period following the initial diastolic flow period;
• formulating a diastolic index from a combination of the first and second volume change rates;
• and
• comparing the diastolic index for each of a plurality of hearts.

A method for evaluating cardiac diastolic function, the method comprising:

• measuring a first volumetric flow of blood through a first heart, wherein the first heart includes a first predetermined condition;
• determining initial and intermediate volume change rates during a diastolic flow period of the first volumetric flow, the intermediate volume change rate following the initial volume change rate;
• formulating a first diastolic index from a combination of the initial and intermediate volume change rates of the first volumetric flow;
• quantifying at least one preselected feature of the first volumetric flow;
• weighting the at least one volumetric flow feature with the diastolic index;
• measuring a second volumetric flow of blood through a second heart, wherein the second heart includes a second predetermined condition;
• determining initial and intermediate volume change rates during a diastolic flow period of the second volumetric flow, the intermediate volume change rate following the initial volume change rate;
• formulating a second diastolic index from a combination of the initial and intermediate volume change rates of the second volumetric flow;
• quantifying the at least one preselected feature selected for the first volumetric flow for the second volumetric flow;
• weighting the at least one volumetric flow feature of the second volumetric flow with the second diastolic index;
• and
• comparing the at least one weighted feature between each of the first and second volumetric flows.
