    Background: Early systolic lengthening is a echocardiographic strain parameter previ- ously used to determine the lesion severity in patients with stable coronary artery dis- ease. In the present study, we aimed to evaluate the relationship between early systolic lengthening and anatomic SYNTAX score in troponin (−) and (+) groups among patients with non-ST-elevation acute coronary syndrome (ACS). Methods: A total of 95 patients diagnosed with non-ST-elevation ACS were included in the prospective, non-randomized, single-center study. The patients were categorized into 2 groups as troponin (+) and troponin (−). The patients were evaluated in terms of echocardiographic, clinical, and angiographic parameters. Results: The baseline characteristics, including age (58 ± 13 vs. 60 ± 10 respectively, P = .340), a history of hypertension (67.1% vs. 64%, respectively, P = .479), diabetes (28.6% vs. 32%, respectively, P = .467), global longitudinal strain (−14.37 ± 5.11 vs. −16.42 ± 3.93, respectively, P = .095), left ventricular ejection fraction (58.71 ± 8.73 vs. 57.20 ± 8.70, respectively, P = .263), and E/e’ (8.44 ± 2.13 vs. 8.33 ± 1.99, respectively, P = .785), were similar between troponin (+) and troponin (−) groups. Left ventricle end-systolic diam- eter (3.2 ± 0.78; 3.50 ± 0.74 vs. 3.2 ± 0.78, respectively, P = .031), left ventricle end-systolic volume (55.57 ± 32.17 vs. 38.28 ± 13.63, respectively, P = .013), left ventricle end-diastolic volume (115.31 ± 49.54 vs. 91.23 ± 20.57, respectively, P = .042), the rate of early systolic lengthening (65.7% vs. 28%, respectively, P = .001), the duration of early systolic lengthen- ing (24.02 ± 31 ms vs. 15.56 ± 30.19 ms, respectively, P = .009), and the SYNTAX score (16 ± 11 vs. 10 ± 10, respectively, P = .023) were higher in the troponin (+) group. Furthermore, a significant correlation was found between early systolic lengthening and SYNTAX score (r = 0.43, P < .001). Conclusion: The rate and duration of early systolic lengthening were higher in patients in the troponin (+) group. Early systolic lengthening is related to SYNTAX score in patients with non-ST-elevation ACS.
