There are no enough data regarding the association of fragmented QRS (fQRS) on electrocardiography (ECG) with angiographically detected coronary artery disease (CAD) severity in patients with stable CAD. We aimed to investigate the relationship of fQRS with CAD severity and total atherosclerotic burden that is defined by Gensini score in stable CAD patients undergoing elective coronary angiography.
Materials and Methods: 132 stable CAD patients who underwent elective coronary angiography were included into the study. Patients were divided into two groups regarding presence or absence of fQRS on ECG. The groups were compared regarding angiographically detected Gensini score.
Results: 38 patients had fQRS on ECG and 94 patients did not have fQRS on ECG. The groups were similar regarding demographic characteristics. Patients with fQRS on ECG had statistically significantly higher Gensini score compared to patients without fQRS. (39.8±24.6 vs. 21.2±15.3, p< 0.001).
Conclusion: Presence of fQRS on ECG is a predictor of CAD severity and total atherosclerotic burden detected by Gensini score. As a simple and easily accessible parameter, fQRS may be useful to predict CAD severity in stable CAD patients undergoing elective coronary angiography.
