A circulatory dynamics measurement apparatus, comprising: a pressure application member configured to compress a predetermined region of a body of a measured subject; a pressure detection unit configured to detect a compression pressure of the pressure application member; a pressure control unit configured to change the compression pressure of the pressure application member; a storage unit configured to store a pulse wave value, which is an amplitude value of a pulse wave generated at the predetermined region based on the compression pressure, and a compression pressure (P1, P2 or P3), which is detected by the pressure detection unit, in association with each other as the pressure control unit changes the compression pressure; a calculation unit (17, 18; 30) configured to calculate a non-blood pressure circulatory dynamics index and at least either one of a systolic blood pressure and a diastolic blood pressure and using the compression pressure and the pulse wave value that are associated with each other; and a display unit configured to show a graph including an axis indicating blood pressure and an axis indicating a non-blood pressure circulatory dynamics index, wherein the display unit shows in a plotting area of the graph a position defined by the calculated blood pressure and the calculated non-blood pressure circulatory dynamics index, wherein the non-blood pressure circulatory dynamics index includes at least a blood vessel hardness index, and the calculation unit (17, 18; 30) is configured to calculate the blood vessel hardness index based on an envelope formed by a cumulatively added pulse wave value (X1+X2+X3) generated by cumulatively adding the pulse wave values (X1, X2, X3) and by the compression pressure (P1, P2 or P3) associated with the pulse wave value (X1, X2, or X3). a pressure application member configured to compress a predetermined region of a body of a measured subject; a pressure detection unit configured to detect a compression pressure of the pressure application member; a pressure control unit configured to change the compression pressure of the pressure application member; a storage unit configured to store a pulse wave value, which is an amplitude value of a pulse wave generated at the predetermined region based on the compression pressure, and a compression pressure (P1, P2 or P3), which is detected by the pressure detection unit, in association with each other as the pressure control unit changes the compression pressure; a calculation unit (17, 18; 30) configured to calculate a non-blood pressure circulatory dynamics index and at least either one of a systolic blood pressure and a diastolic blood pressure and using the compression pressure and the pulse wave value that are associated with each other; and a display unit configured to show a graph including an axis indicating blood pressure and an axis indicating a non-blood pressure circulatory dynamics index, wherein the display unit shows in a plotting area of the graph a position defined by the calculated blood pressure and the calculated non-blood pressure circulatory dynamics index, wherein the non-blood pressure circulatory dynamics index includes at least a blood vessel hardness index, and the calculation unit (17, 18; 30) is configured to calculate the blood vessel hardness index based on an envelope formed by a cumulatively added pulse wave value (X1+X2+X3) generated by cumulatively adding the pulse wave values (X1, X2, X3) and by the compression pressure (P1, P2 or P3) associated with the pulse wave value (X1, X2, or X3).
