    Objective: Cardiac syndrome x (CSX) is defined as typical exertional angina, one or more abnormal cardiac stress test(s), and normal coronary arteries after exclusion of spontaneous or inducible epicardial coronary spasm. The aim of this study was to investigate cardiovascular adverse events risks in patients with CSX. For this purpose, spatial QRS-T angle that is predictor of these risks was evaluated in patients with CSX and control subjects. Methods: In a retrospective study, a total of 179 subjects (95 patients with CSX, 84 control) were examined. Control subjects had a normal coronary computed tomography. Spatial QRS-T angle value was calculated and compared in patients with CSX and control group, p values <0.05 were considered as statistically significant. Results: There was a statistically significant difference between the groups in terms of spatial QRS-T angle values [control group spatial QRS-T angle value median 35 (12.5 - 60), CSX group spatial QRS-T angle value median 51 (27 - 115), p<0.001]. Conclusion: According to our results, spatial QRS-T angle value was elevated in patients with CSX than in normal population. Furthermore, these results may indirectly suggest that the risk of adverse cardiac events may be increased in patients with CSX.
