Evaluation of the effect of coronary artery lesions on left ventricular myocardial movement in early systolic stage with two-dimensional speckle tracking imaging echocardiography / 中国医学影像技术

ABSTRACT

Objective: To explore the feasibility of two-dimensional speckle tracking imaging echocardiography (2D-STE) in evaluation of the impact of coronary artery lesions on left ventricular myocardial movement in early systolic stage. Methods: A total of 179 patients with suspected coronary heart disease who underwent coronary angiography were collected, and left ventricular heart sarcomeres of all patients were divided into control group (no stenosis), mild group (stenosis ≤ 50%), moderate group (50%
