Application Of Intravascular Ultrasound And Fractional Flow Reserve On Diagnosis And Treatment Of Coronary Heatr Disease

Objective:The aim of this study is to investigate whether there is adifference between intravascular ultrasound (IVUS) and fractional flowreserve(FFR) on diagnosis and treatment of intermediate coronary heartdisease.Methods:55patients with coronary heart disease adminitted to SecondHospital of Jilin University from April2011to September2011were enrolledin this study.They were divided into two groups,one was IVUS guiding groupand the other was FFR guiding group.Six months later,we compared theprognosis of these two groups.Results: The number of stents used per patient was0.43±0.50in IVUSgroup and0.43±0.50in FFR group (p=0.025).Six month later,1patient died inthe FFR group,while no patient died in the IVUS group.Both in the IVUSgroup and FFR group no patient got myocardial infarction or need repeatrevascularization. The6-month event rate was0%(0patient) in the IVUSgroup and4%(1patients) in the FFR group (P=0.45).18(60%) patients in theIVUS group were free from angina at six month,as compared with22(88%)patients in the FFR group.Conclusion:1.On the base of that measurement of FFR in intermediate coronary heartdisease undergoing PCI does not increase the rate of MACE,it can reduces thenumber of stents and the rate of angina.2.FFR could be the important basis to decide weather intermediatecoronary heart disease should accept PCI.
