Background: We aimed to determine the association of upright T wave in lead V1 and stenosis of coronary artery branches in patients who underwent coronary angiography at our center and had normal electrocardiogram. Methods: We retrospectively reviewed the clinical and coronary angiography data of patients who had normal electrocardiogram. Presence of coronary artery disease was compared between patients with and without upright T wave in lead V1 as well as other clinical and angiographic parameters. Results: Data of a total of 100 patients with upright T wave in lead V1 was compared with 100 patients with completely normal electrocardiograms. Frequency of males and CAD patients were higher in the upright T wave group. However, the groups did not differ statistically about the cardiovascular risk factors. Based on the multivariable regression model and after adjustment for confounding factors (i.e. gender, dyslipidemia and smoking), presence of upright T wave in the V1 lead could predict the presence of coronary artery disease (Odds ratio=3.30, 95% CI:1.736.29; P<0.001). Conclusion: We suggest that the use of electrocardiogram, particularly the presence of upright T wave in lead V1 could help to early diagnosis and treatment of CAD in patient’s chest pain.
