There is a known relationship between frontal-QRS-T (F-QRS-T) angle and coronary artery disease (CAD). This study examined the relationship between F-QRS-T angle changes and CAD severity in patients with stable CAD. A total of 202 patients were included in the study after the implementation of exclusion criteria among 894 patients, who were admitted to the outpatient clinic with stable angina pectoris between September 2018 and September 2019. The F-QRS-T angle calculated on the 12-lead electrocardiograms (ECGs) of the patients (taken in the outpatient clinic), and the CAD severity calculated using the Gensini score in patients undergoing coronary angiography were compared. Of the patients included in the study, 38.6% were female and 61.4% were male. The mean age was calculated as 60.16±11.27 years, and 52% of the patients had hypertension. There was no difference between the groups in terms of demographic and clinical values. In a comparison of CAD severity and F-QRS-T angles, the F-QRS-T angle was seen to be statistically significantly higher in the severe CAD group [91°° (102/79)] compared to the group with mild CAD [53°° (64/38)]. In the multivariate logistic regression analysis, there was a significant association between the F-QRS-T angle (odds ratio=1.09, 95% confidence interval=1.06–1.11, p<0.001) and CAD severity. It seems that CAD severity in patients who were non-diabetic and had stable angina pectoris is associated with the F-QRS-T angle.

Thrombolysis in Myocardial Infarction Frame Count (TFC) is an index that provides a quantitative evaluation of coronary microvascular dysfunction. In this study, we aimed to examine the effect of C...

Objectives: The frontal QRS-T (f-QRST) angle is a measure of depolarization and repolarization heterogeneity and may be a predictor of poor ventricular health. We aimed to investigate whether the f-QRST angle indicates myocardial damage and predicts newly diagnosed true hypertension (HT) in patients with white coat hypertension. Methods: We measured the f-QRST angle of 63 subjects with WHC and 105 patients with newly diagnosed HT. Laboratory tests and ABPM were followed up in all patients. The f-QRST angle was calculated on the surface ECGs. Results: Of the patients in the study, 38.9% were female and 61.1% were male. The mean age was calculated as 59 ± 11 years. A comparison between both groups with the f-QRST angles was seen to be statistically significantly higher in the true HT group. The results of the receiving operating characteristic curve showed that the AUC value of the f-QRST angle was 0.94 (95% confidence interval, 0.91–0.97), the cutoff value was 60.5°, the sensitivity was 89.5%, and the specificity was 81%. Conclusion: In our study, the f-QRST angle was found to be lower in patients with WHC than in true hypertensive patients. We think that ECG, which is a simple test, can be used to distinguish between true HT and WHC.
