Abstract
Purpose: Evaluation of left ventricular functional changes using pericardial layer assessment through speckle tracking echocardiography (STE) in patients with chronic coronary syndrome.
Subjects and methods: 92 patients with chronic coronary syndrome, including 58 males and 34 females, with an average age of 68.43 ± 10.36 years, consented to participate in the study. All had ultrasound to STE a Philips echocardiogram machine, recording 2-chamber, 3-chamber and 4-chamber cross-sections. Then analyzed offline using STE software, analyzing strain peaks according to the epicardial layer and endocardium layer. Evaluate myocardial movement disorders and compare with the results of coronary angiography using DSA.
Results: The epicardial LS and GLS indexes were lower than those in the endocardium, p < 0.001. GLS of the epicardium -11.07 ± 2.78 was lower than the endocardium -12.84 ± 3.34; p < 0.001. If considering the significant coronary stenosis (> 50%), the diagnosis of LAD stenosis, STE-epi has Se 87.0% and Sp 60.0%; κ = 0.43; the diagnosis of LCx stenosis, STE-epi has Se 79.2% and Sp 77.9%; κ = 0.50; the diagnosis of RCA stenosis, STE-epi has Se 84.7% and Sp 54.3%, κ = 0.39.
Conclusion: For patients with chronic coronary syndrome, pericardial layer speckle tracking echocardiography imaging provides better diagnostic accuracy for regional wall motion abnormalities compared to the endocardial layer.
