Introduction: To date, there are few reports on computed tomography angiography (CTA) in combination with stress myocardial perfusion imaging (SMPI) in the diagnosis of coronary slow flow (CSF). Methods: A total of 62 patients with suspected CSF who were scheduled to undergo CTA, SMPI and coronary angiography (CAG) from June 2019 to June 2021 were selected. With the results of CAG as the gold standard, the value of CTA plus SMPI in the diagnosis of CSF was analyzed. Results: Of the 62 patients, 52 (83.87%) were diagnosed with CSF by CAG. The results of the Kappa consistency test showed that SMPI alone, CTA alone and SMPI plus CTA had 0.565, 0.396 and 0.881 consistency, respectively, with CAG in the diagnosis of CSF. The sensitivity, specificity, accuracy, positive predictive value and negative predictive value of SMPI plus CTA in the diagnosis of CSF were 98.08% (51/52), 90.00% (9/10), 96.47% (60/62), 98.08% (51/52), and 90.00% (9/10), respectively, all higher than those of SMPI or CTA alone (P<0.05). The areas under the receiver operating characteristic curves of SMPI alone, CTA alone and SMPI plus CTA in the diagnosis of CSF were 0.754, 0.771 and 0.940, respectively. Conclusion: CTA and SMPI have high diagnostic values for CSF, and the results of their combination have high consistency with those of CAG.
