| Background: Few studies have investigated P-wave and T-wave axes, most of which focus on mortality. The frontal TP angle (fT-Pa) is a novel ECG-derived parameter of ventricular repolarization. We aimed to evaluate the association between fT-Pa and SYNTAX-1 (SS-1) and SYNTAX-2 (SS-2) scores in patients with acute non-ST-segment elevation myocardial infarction (ANSTEMI).Methods: This retrospective study included 158 ANSTEMI patients undergoing coronary angiography. The study population was stratified based on SS-1 (≤ 22 vs.> 22) and SS-2 (≤ 26.2 vs.> 26.2). The fT-Pa was calculated by subtracting the P-wave axis from the T-wave axis, both obtained from the ECG device's built-in software, and compared between groups.Results: fT-Pa showed significant correlations with age (r= 0.242, P= 0.003), SS-2 (r= 0.229, P= 0.005), and T-wave axis (r=--0.626, P< 0.001). Both age and fT-Pa were significantly correlated with and predictive of SS-2 (β= 0.679; OR, 0.700 [95% CI, 0.584 to 0.816]; P< 0.001 for age) and (β= 0.147; OR, 0.048 [95% CI, 0.012 to 0.085; P= 0.010 for fT-Pa). ROC curve analysis identified an fT-Pa cutoff of 36.5 (64% sensitivity, 68% specificity; AUC, 0.674; P< 0.001) for predicting SS-2> 26.2, and a cutoff of 39.5 (70% sensitivity, 62% specificity; AUC, 0.692; P= 0.010) for predicting SS-1> 22.Conclusions: fT-Pa showed a stronger correlation and association with SS-2 than with SS-1. This parameter may serve as a simple, reproducible tool for predicting coronary artery disease complexity, even in patients with normal T-wave and P-wave axis ranges. |
