Abstract: Objective To explore the clinical significance of blood flow reserve fraction in the treatment of coronary stent implantation.Methods A total of 46 patients with positive coronary angiography were included.Criteria for positive coronary angiography:coronary angiography confirmed at least a coronary artery stenosis was more than or equal to 50%.According to the results,the patients were divided into the control group(24 cases) and observation group(22 cases).Results 1.There was no significant difference in baseline level(P>0.05);2.The operation time,number of stents and the contrast agent dosage of the observation group were (63.20±9.92)min,(0.50±0.65) and (182.94±39.30)mL,which were significantly less than those of the control group,the differences were statistically significant(operation time t=2.69,P=0.01;number of stents t=2.56,P=0.02;contrast agent dosage t=6.98,P=0.00).There was no significant difference between the control group and the observation group in angina pectoris and MACE attack.Conclusion Blood flow reserve score is an important guiding parameter for PCI treatment of coronary artery stenosis.
