The invention relates to a coronary stent based hemorheological monitoring device and a coronary stent based hemorheological monitoring method. The device is characterized by comprising a coronary stent, an integrated circuit and external processing equipment; the coronary stent serves as an antenna, and the integrated circuit is fixed to a blood vessel of the coronary stent; the integrated circuit comprises an energy supply module, a hemorheological detection module, a memory, a data processor and a first radio-frequency transceiving module, and the energy supply module is used for supplying power to the integrated circuit; the hemorheological detection module transmits detected hemorheological signals to the data processor through the memory, and then the data processor converts the hemorheological signals into digital signals and transmits the digital signals to the external processing equipment through the coronary stent by the aid of the first radio-frequency transceiving module.
