Özet

Background: Early systolic lengthening is a echocardiographic strain parameter previously used to determine the lesion severity in patients with stable coronary artery disease. 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 diameter (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 lengthening (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.
