Abstract:: Abstract: Objective To explore the application of dual-source CT derived fractional flow reserve (FFR) for percutaneous coronary intervention (PCI) in patients with coronary heart disease. Methods A retrospective study was conducted on 68 coronary heart disease patients admitted from January 2022 to June 2022. Whether PCI was carried out was dependent on coronary angiography in control group (n=34) and dual-source CT derived FFR in research group (n=34). The two groups were compared for general data, length of diseased blood vessels, number of stents, hospitalization expenses and incidence of adverse reactions. Results The differences in age, smoking history, diabetes, hypercholesterolemia and angina pectoris between two groups were trivial (P>0.05). After treatment, research group had less number of stents, lower hospitalization costs, and shorter diseased blood vessels than control group (P<0.05). The 6-month follow-up showed that the total incidences of adverse reactions in research group and control group were 17.65% and 58.82% (P<0.05). Conclusion Using dual-source CT derived FFR to guide PCI can reduce the number of stents and hospitalization costs, and lower the incidence of cardiovascular adverse reactions.
