| BackgroundFrontal and spatial QRS-T angles reflect ventricular repolarization heterogeneity and may be associated with coronary artery disease severity. This study aimed to evaluate their relationship with SYNTAX and Gensini scores in non-ST elevation myocardial infarction (NSTMI) patients.MethodsA total of 1188 patients with NSTMI were retrospectively analyzed. Frontal and spatial QRS-T angles were calculated from 12-lead digital ECGs using the Rautaharju method. Correlation, univariate and multivariate linear regression, ROC, and logistic regression analyses were performed to assess their associations with SYNTAX and Gensini scores.ResultsThe spatial QRS-T angle was independently associated with SYNTAX and Gensini scores in multivariate linear regression, whereas the frontal QRS-T angle showed no significant association. Patients with SYNTAX score >32 had significantly higher spatial QRS-T angles. ROC analysis demonstrated that spatial QRS-T angle >105.2° predicted high SYNTAX scores with an AUC of 0.80. Logistic regression confirmed the spatial angle as an independent predictor of high SYNTAX score (OR: 1.04, 95% CI: 1.02--1.06; p<0.001).ConclusionThe spatial QRS-T angle, but not the frontal angle, is a significant independent predictor of severe coronary artery disease in NSTMI patients. It may serve as a simple, non-invasive ECG marker for identifying patients with high atherosclerotic burden. |
