Abstract：Objective To discuss the diagnostic value of load myocardial nuclein perfusion imaging combining coronary computed tomographic angiography (CTA) to coronary slow flow (CSF). Methods The patients (n=237, male 159, female 78, aged from 38 to 69 and average age=52.4±11.3) with angina pectoris undergone joint examinations of CTA combining load myocardial nuclein perfusion imaging and meanwhile coronary angiography (CAG) within a month were retrospectively analyzed from Jan. 2008 to Jan. 2014. Taking CAG as a golden standard of CSF diagnosis, and comparing it with the joint examination of load myocardial nuclein perfusion imaging combining CTA, the diagnostic value of the joint examination to CSF was reviewed. Results The sensitivity of the joint examination in diagnosing CSF was 65.6%, specificity, 97.1%, omission diagnostic rate, 34.4%, misdiagnosis rate, 2.9%, total coincidence rate, 92.8%, positive likelihood ratio (PLR), 22.62, negative likelihood ratio (NLR), 0.35, positive predictive value, 77.8%, and negative predictive value, 94.8%. The consistency of 2 diagnostic methods was tested by using Kappa test and the result showed that Kappa value was 0.67 (P<0.001, consistency being higher). Conclusion The joint examination of load myocardial nuclein perfusion imaging combining CTA has higher diagnostic value in CSF patients, which provides a reliable non-invasive examination approach for diagnosing CSF in clinic.
