Introduction: CSF is an angiographic finding characterized by delayed filling of the distal vessels with no visible stenosis in epicardial coronary arteries. The aim of this study was to specify repolarization changes in the ECG of patients with CSF hospitalized with patients ACS diagnosis. Method: In this cross-sectional study, ۳۷ patients hospitalized with ACS diagnosis undergoing angiography and having CSF evidence according to TIMI flow rate entered the study. The files of ۳۷ subjects with normal coronary were studied as the control group. The patients were analyzes using the changes in ST-T segment, as well as QT, QTc and TPe values with the results analyzed using SPSS۲۱. Results: According to the multivariate logistic regression model, two factors of male sex (OR = ۱۴.۳۲۴, P = ۰.۰۰۱) and history of diabetes mellitus (OR = ۶.۲۶۵, P = ۰.۰۲۹) were the predictors of incidence of CSF. Nevertheless, none of QT, QTc, TPe factors, or the ratio of TPe to QT was associated with the occurrence of CSF. Conclusion: The predictive and related factors to CSF incidence were male gender and history of diabetes mellitus. Accordingly, the incidence of CSF is not associated with the increase in electrocardiographic variations such as ST-T changes, T inversion, left ventricular hypertrophy (LVH) as well as changes in QT, QTc, and TPe criteria. In other words, the occurrence of electrocardiographic changes is not associated with the existence of CSF.
