System for determining a coronary pulse wave velocity, comprising: - an interface for receiving a signal of proximal blood pressure in a coronary artery and for receiving a signal of distal blood pressure in said coronary artery; - a processing device, configured to: - on the basis of a received signal of proximal pressure, identify a time Tfmp of the start of a rising edge and a time Tfdp of the start of a falling edge; - calculate the duration T between the identified times Tfdp and Tfmp; - on the basis of a received signal of distal pressure, identify a time Tfdd of the start of the falling edge; - after having subtracted said calculated duration T from the time Tfdd of the start of the falling edge of the signal of distal pressure, identify a time Tfmd of the start of the rising edge of the signal of distal pressure; - collect the value of the distance between the place of measurement of the proximal pressure and the place of measurement of the distal pressure; - calculate the duration separating the start of the respective identified rising edges of the signal of proximal pressure and of the signal of distal pressure; - calculate the coronary pulse wave velocity depending on said duration separating the rising edges and said collected distance value. - an interface for receiving a signal of proximal blood pressure in a coronary artery and for receiving a signal of distal blood pressure in said coronary artery; - a processing device, configured to: - on the basis of a received signal of proximal pressure, identify a time Tfmp of the start of a rising edge and a time Tfdp of the start of a falling edge; - calculate the duration T between the identified times Tfdp and Tfmp; - on the basis of a received signal of distal pressure, identify a time Tfdd of the start of the falling edge; - after having subtracted said calculated duration T from the time Tfdd of the start of the falling edge of the signal of distal pressure, identify a time Tfmd of the start of the rising edge of the signal of distal pressure; - collect the value of the distance between the place of measurement of the proximal pressure and the place of measurement of the distal pressure; - calculate the duration separating the start of the respective identified rising edges of the signal of proximal pressure and of the signal of distal pressure; - calculate the coronary pulse wave velocity depending on said duration separating the rising edges and said collected distance value. - on the basis of a received signal of proximal pressure, identify a time Tfmp of the start of a rising edge and a time Tfdp of the start of a falling edge; - calculate the duration T between the identified times Tfdp and Tfmp; - on the basis of a received signal of distal pressure, identify a time Tfdd of the start of the falling edge; - after having subtracted said calculated duration T from the time Tfdd of the start of the falling edge of the signal of distal pressure, identify a time Tfmd of the start of the rising edge of the signal of distal pressure; - collect the value of the distance between the place of measurement of the proximal pressure and the place of measurement of the distal pressure; - calculate the duration separating the start of the respective identified rising edges of the signal of proximal pressure and of the signal of distal pressure; - calculate the coronary pulse wave velocity depending on said duration separating the rising edges and said collected distance value.
