Summary

To study the effect of myocardial microcirculation disturbance on coronary flow reserve fraction, compare the evaluation value of IMR, FFR and QCA on myocardial ischemia, and discuss the correlation among them.

Conditions

  • Myocardial Ischemia

Interventions

COMBINATION_PRODUCT

FFR

FFR measurement: Pressure guid wire(radianalyzer Xpress 12711) is produced in Switzerland. After the pressure of the aorta and the pressure guide wire is balanced, Send the pressure guide wire to the distal part of the lesion(more than 20 mm away from the lesion) . Adenosine is injected into the vein,then,record the FFR index 3 times and take the average value as the final measurement index.
