- Abstract
Aim: Early risk stratification based on Gensini score plays a crucial role to identify the need for early invasive strategy in patients with NSTEMI. The predictive role of frontal QRS-T angle [f (QRS-T)] on the atherosclerotic burden of coronary artery disease is less clear in NSTEMI patients compared to STEMI patients. In this study, we aimed to investigate the relationship between f (QRS-T) and Gensini score in NSTEMI patients. Material and Method: Total of 248 patients with the diagnosis of NSTEMI transferred to coronary care unit were included in the study. f (QRS-T) was calculated as the absolute value of the difference between the frontal plane QRS and T axes based on automatic report of ECG machine. Gensini score was computed using an Gensini score calculator by well-experienced two cardiologists. The study population was divided into two groups based on the low (=45), and high Gensini score (>45). Results: Left ventricular ejection fraction was significantly lower in the group with high Gensini score (46.1±8 vs. 53.3±7; p<0.001). When the angiographic views was examined and revascularization strategies were compared, it was detected that responsible lesion was seen in LAD most frequently (p<0.001) and revascularization was performed most frequently for LAD (P<0.001). The f (QRS-T) angle, the primary endpoint of the study, were significantly higher in the group with high Gensini score (54±47 vs. 84±54; p<0.001). We determined that f (QRS-T) angle is an independent indicator for high Gensini score, based on the univariate and multivariate logistic regression analysis. Based on Receiver-operating characteristic (ROC) analysis, finding f (QRS-T) angle higher than 61.5°'in NSTEMI patients predicts patients with high Gensini score (>45) with% 70 sensitivity and% 61 specificity. Conclusion: In NSTEMI patients, f (QRS-T) has been found to be a useful decision-making tool to predict Gensini score to assess early invasive strategy.
