In this study, patients were retrospectively included, univariate and multivariate analysis of factors affecting their diagnosis inconsistencies was performed, and a new diagnostic model was constructed by logistic regression.
The evaluation of coronary function is becoming more and more important in the guidelines, in which coronary flow reserve (FFR) is the gold standard for diagnosis, but its measurement process requires the application of adenosine, vasodilator, etc. Some patients cannot be measured because of asthma and low blood pressure. A new instantaneous wave-free ratio (iFR), contrastive flow reserve fraction (cFFR) and quantitative flow fraction (QFR) have been developed for the evaluation of coronary function. However, in some patients, the new coronary function evaluation methods were inconsistent with FFR. In this study, patients were retrospectively included, univariate and multivariate analysis of factors affecting their diagnosis inconsistencies was performed, and a new diagnostic model was constructed by logistic regression.

Patients who met the inclusion criteria and those who did not meet the exclusion criteria were admitted to the Department of Cardiovascular Medicine of Peking University Third Hospital from January 1, 2019 to November 31, 2023.
Exclusion Criteria:
In this single-center cross-sectional study, we included patients with non-acute myocardial infarction who were admitted to the Department of Cardiology at Peking University Third Hospital for FFR testing from January 2019 to December 2021.
