Abstract

Background: Chronic coronary syndrome (CCS) remains a global leading cause of death, with high incidence and asymptomatic progression. 2D speckle-tracking echocardiography (2D-STE) has emerged as a valuable tool for detecting impaired regional myocardial function in coronary artery disease patients, offering reliable quantification of myocardial deformation in CCS. Objectives:. Evaluation of cardiac speckle-tracking echocardiographic indices in chronic coronary syndrome. Materials and methods: A cross-sectional study was conducted on 40 patients who underwent speckle tracking echocardiography and coronary angiography for diagnostic confirmation, following a timeline from December 2023 to January 2025. Results: This study was conducted on 40 patients with an average age of 67.97 ± 10.38 years, of which the group aged over 70 accounted for 45%, with a similar male-to-female ratio. GLS-avg showed a significant difference between the group with stenosis <70% (-18.69 ± 1.88) and the group with stenosis ≥70% (-12.91 ± 4.58) (p<0.001). The GLS-avg value for normal coronary arteries was -18.69 ± 1.88; for single-vessel disease, it was -14.65 ± 4.33; for two-vessel disease, -13.13 ± 4.81; and for three-vessel disease, -11.28 ± 4.46. The study also found no difference in GLS between the groups with and without regional wall motion abnormalities. Conclusions: Two-dimensional speckle-tracking echocardiography is a valuable tool for predicting coronary artery disease in patients with stable angina.
