Abstract

Objectives Coronary computed tomography angiography (CCTA) has been proven accurate for diagnosing coronary artery disease (CAD). However, its ability in correctly triaging CAD remained unknown.

Methods Patients without known CAD underwent CCTA from January 2008 to Febuary 2010. Only those patients who had CCTA before coronary angiography (CAG) were included. The patients who underwent only one CAG during this period were served as the control. The rate of percutaneous coronary intervention (PCI), coronary artery bypass graft (CABG), medical therapy and normal CAG were calculated and compared.

Results During the hospitalisation, CAG was performed in 622 pts (179 female and 443 male) in the control group, which resulted in 353 (56.75%) cases of PCI, 18 (2.89%) cases of CABG, 138 (22.19%) cases of medication and 113 (18.17%) cases of normal CAG. After CCTA, CAG was performed in 132 cases (38 female and 94 male), which led to 81 (61.36%) cases of PCI, 9 (6.82%) cases of CABG, 31 (23.48%) cases of medication and 11 (8.33%) cases of normal CAG. In comparison with control, CCTA resulted in fewer normal CAG and more CABG (P < 0.05).

Conclusions CCTA has significantly improved the patients triage by avoiding unnecessary intervention and referring more to CABG.
