Abstract

A circulatory-organ evaluating apparatus for evaluating a circulatory organ of a living subject, including a display device, and a control device which controls the display device to simultaneously and graphically display a blood pressure, an augmentation index, and pulse-wave-velocity-related information of the subject.

Claims

1. A circulatory-organ evaluating apparatus for evaluating a circulatory organ of a living subject, comprising:

a display device; and

a control device which controls the display device to simultaneously and graphically display a blood pressure, an augmentation index, and pulse-wave-velocity-related information of the subject.

2. A circulatory-organ evaluating apparatus recited in claim 1, wherein the display device displays a multi-dimensional graph representing at least the blood pressure, the augmentation index, and the pulse-wave-velocity-related information of the subject.

3. A circulatory-organ evaluating apparatus recited in claim 2, wherein the multi-dimensional graph includes a standard figure representing a standard blood pressure, a standard augmentation index, and standard pulse-wave-velocity-related information.

4. A circulatory-organ evaluating apparatus recited in claim 2, wherein the multi-dimensional graph represents respective time-wise changes of the blood pressure, the augmentation index, and the pulse-wave-velocity-related information of the subject.

5. A circulatory-organ evaluating apparatus according to claim 4, further comprising a memory device which stores at least one past set of evaluation information including at least a blood pressure, an augmentation index, and pulse-wave-velocity-related information that were measured from the subject in at least one past measuring operation, wherein the control device controls, based on the set of evaluation information stored in the memory device, the display device to display the multi-dimensional graph representing the respective time-wise changes of the blood pressure, the augmentation index, and the pulse-wave-velocity-related information of the subject.

6. A circulatory-organ evaluating apparatus according to claim 1, further comprising an input device which is operable by an operator to input identification information identifying the subject.

7. A circulatory-organ evaluating apparatus according to claim 1, further comprising:

a blood-pressure measuring device which measures the blood pressure of the subject;

an augmentation-index determining device which determines the augmentation index of the subject; and

a pulse-wave-velocity-related-information obtaining device which obtains the pulse-wave-velocity-related information of the subject.
